Scarlet: what kind of insect is this? The main types, harm, methods of struggle. Mealybug on indoor plants Mealybug on citrus fruits how to fight

All lovers of greenery in the house need to know what a mealybug looks like, how to fight on indoor plants with it, as well as the main methods of preventing pest infestation. These creatures look like aphids. Their size ranges from 3 to 7 mm. From above, pests seem to be sprinkled with flour. This substance protects them from drying out, since they do not have an external solid chitinous apparatus. Recognizing the presence of mealybugs is not difficult, as they form a specific cotton-like coating on the leaves. In these fluffy masses, the females of these pests can lay up to 500-600 eggs. This contributes to the very rapid spread of these creatures on neighboring colors.

If the degree of infection is low, it is quite possible to get by with folk remedies, which have a milder effect and are completely harmless to humans and pets. If the first signs of leaf damage were not detected in a timely manner, it is necessary to use more effective and efficient chemicals and agricultural practices to combat these creatures. In some cases, it is advisable to use all possible methods at once to more quickly eliminate pests from the leaves of indoor plants.

How to start the fight against mealybugs?

Usually the activation of these pests occurs in the spring and autumn time. The maturation of mealybug larvae largely depends on the temperature regime and the relative humidity of the air. This pest multiplies most rapidly at 25°C. For a long time, worms on indoor plants live in relatively small populations. In this case, they do not cause significant harm. While creating favorable conditions the numbers of these pests can increase rapidly. More often, mealybugs infect weakened plants that have not received necessary care or suffered from an excess of nitrogen that disrupts metabolism. On healthy young indoor flowers, these pests usually do not settle, as the plants have their own defense mechanisms that repel these insects.

In order to quickly get rid of the mealybug, you need to carefully examine the affected flower and, if possible, remove all the leaves and shoots that are most strongly covered with these creatures. It is necessary to isolate the infected plant from others. Among other things, you need to take the old soft toothbrush and, moistening it in a soapy solution, carefully remove insects from those shoots that cannot be removed. Moistened cotton swabs can also be used to combat plaque on indoor plants, but this is less convenient. If possible, you need to rinse the plant with running water after removing the existing foci of pest settlement. Such a procedure will reduce their number and increase the effect of the use of folk and chemical remedies designed to combat these creatures.

If the indoor flower has pronounced signs of damage by this pest, it is necessary to act in a directed way using special means. Currently, many chemicals have been developed that allow you to quickly eliminate these small insects.

The most commonly used include the following:

  • Actellik;
  • Aktar;
  • Bankol;
  • Inta-Vir;
  • Vertimek;
  • Karbofos;
  • Tanrek;
  • Confidor Extra;
  • Fitoverm.

The cost of such funds, depending on their variety, can range from 10 to 120 rubles. With a strong infection of the plant, it is not easy to quickly get rid of the mealybug, since the flower is weakened and may even die soon. It is necessary to select an insecticide on an individual basis, since these pests have the ability to acquire resistance to drugs of this type. With a strong infection, it is better to start applying immediately. Aktar. It is a very powerful insecticide with a systemic effect.

If it was not possible to purchase this product in a flower shop, then to eliminate pests that have severely affected the plant, it is best to use Inta-Vir or Confidor. These drugs have a powerful effect, but at the same time they are relatively safe for humans. With severe damage to the plant, you can use Karbofos and Vertimek. These products have a high degree of toxicity, so they should be used very carefully. It is best to carry out procedures outdoors. This will minimize the risk to humans and animals.

If the defeat of the mealybug is mild, drugs can be used Aktara or Fitoverm. They are slower acting, but are considered safe. Any insecticide, regardless of their class, must be applied strictly following the instructions. To enhance their action after treatment, the houseplant should be covered with a transparent bag and left for several hours. It is very important for this period to protect it from direct sunlight so that the flower does not die due to an increase in temperature inside such an impromptu greenhouse. With a strong infection, it is best to treat the plant with insecticides at least 3-4 times. The interval between procedures should be at least 5-7 days. It is very important that the air temperature during the treatment of plants from the mealybug was at least + 22 ... + 24 ° C. If it fluctuates within + 11 ... + 20 ° C, this will significantly affect the effectiveness of insecticides.

Folk remedies for the fight against mealybugs

Many modern people are afraid to use special chemicals to eliminate pests from indoor plants. Folk remedies in this matter are less effective, but they do not have a toxin effect and cannot harm people living in the house. Such recipes can be successfully applied with a slight damage to plants by a mealybug.

The simplest, but at the same time quite in an efficient way Soap solution is considered to eliminate these pests. This product can be easily made at home. For its preparation, you can take cosmetic, tar and even laundry soap. Suitable and means intended for washing dishes. The soap solution should be thick. The more foam, the better. They need to process not only all the leaves and shoots of the infected plant, but also the windowsill, pallet and pot. This will increase the effectiveness of this folk remedy.

After treatment, it is necessary to leave the soapy solution on the plant for 2-3 hours, then rinse gently. To enhance the effect, you can add a few spoons to this remedy. ammonia. However, when processing such a remedy, it must be washed off after 15-20 minutes. It is worth noting that this folk recipe getting rid of the mealybug is not suitable for all types of plants. It is believed that in some cases, soap can block the stomata present on the stem and leaves, which causes the death of the flower due to disruption of the photosynthesis process. Among other things, solutions containing alcohol should not be used if the plant has tender leaves. This will cause burns.

Garlic is often used to eliminate mealybugs. The poisonous substances contained in it can scare away this pest. To prepare this remedy, you need to take 1 tsp. chopped garlic cloves to a pulp and pour them with 1 glass of water. It is necessary to insist the remedy for 1-2 days, and always in a sealed container. This remedy should be used to wash the leaves every 7-8 days.

To get rid of the mealybug, you can also use onion peel. To prepare the composition, you need to take about 20 g of a carefully crushed plant component and pour 1 liter warm water. You need to insist on the remedy for at least a day, and then use it to spray infected indoor flowers. Usually 2-3 treatments are enough to get rid of the mealybug.

In addition, quite often, a strong infusion of dry tobacco is used to combat this pest. To prepare such a remedy, you need to take about 80 g of shag and pour 1 liter of warm water. The agent must be set aside for a day, then carefully strain and dilute with water until the initial amount of liquid is obtained. This infusion can be used both for spraying and for washing. This product is great for removing white coating on leaves and stems.

How to prevent mealybugs from infecting plants?

However, the most best method the fight against this pest is to prevent its occurrence. If you got into the house new flower, it must be quarantined separately from the rest for at least 1 month. It is imperative to conduct a periodic inspection of all indoor plants, paying particular attention to back side leaf and axils. If worms were detected on the plant at an early stage, this guarantees good effect even when using folk remedies in the fight against them.

Among other things, it must be borne in mind that frequent airing of the room, washing and spraying the leaves with special cleaning solutions can reduce the risk of these pests. In addition, it is desirable to carry out periodic treatment of plants with insecticides. This will prevent an increase in the number of pests if they still hit the flower. For prevention, you can use folk remedies, for example, garlic or onion tincture, which will reduce the risk of the spread of mealybugs.

There are many insects that feed on plants. Mealybug is no exception, it is little creature lives only at the expense of the donor plant, and as soon as it dies, the insect looks for another source of food. Previously, the worm was used to create red paint, but now this type of insect is not used for such purposes.

Description of the insect

As for the development of these insects, they go through only 3 stages: the first stage is being in the eggs; the second is the transformation into a larva and the third is the appearance of an adult. But there are exceptions because some species of worm are viviparous.

Properties and states of the egg

Before the female lays eggs, she leaves the donor plant, that is, the place where she fed. She goes into hiding in order to protect her offspring. The female is engaged in the fact that he releases fibrous weaving and creates a cocoon out of it, it is in this cocoon that the eggs are placed.

Mealybugs are usually very easy to see, most of them can be from below and in the axils of foliage, on petioles and stems. In these places, discharges resembling cotton wool are visible, they contain eggs. Therefore, the plants attacked by the mealybug seem to be covered with cotton wool or fluff. Further, larvae hatch from the eggs, they crawl through the culture and suck the juice.

What plants most often affects and what is dangerous?

Citrus bugs attack citrus crops (grapefruit, citron, tangerine, orange, calamondin). In females, the body is up to 4 mm, it is light pink, covered with a whitish coating. Females lay eggs after 15 days of their lives. Live 3 months. Males are beige, have transparent wings, live 2-4 days.

Grapes are attacked by grapevine. The female has a wide oval body, it is pinkish or yellowish, has a white coating that resembles a powder. Males are quite rare.

Orchids are exotic plants that are very demanding on the conditions of detention. But apart from the hassle of organizing proper lighting, watering and fertilizing flower growers have to deal with diseases and pests that often affect this flower. If a mealybug wound up on an orchid, how ...

These cultures are affected by the bristly bug. In the female, the body is 3.5 mm, has an orange or pinkish tint, and is covered with bloom. And there is also a seaside worm. The female has a body up to 3-4 mm, it is pinkish-gray, with a snow-white coating. Males are smaller and have wings. The larvae are tiny, yellowish in color, they move quickly, they have no plaque.

As a result of the appearance of the mealybug, the flowers stop growing; shoots are deformed; foliage, ovaries, fruits fall off; branches dry up. During their activity, the females secrete honeydew, and then a sooty fungus appears on it.

How to deal with mealybugs on indoor plants?

To destroy the pest from biological preparations, lepidocide is used.

Effective chemicals

Next, spray with a solution of green soap, rubbing 10-15 g in 1 liter of water. Do this spraying 3 times at weekly intervals. You can use tobacco infusion, garlic juice, onion juice or cyclamen decoction instead of soap. You can treat the plant with alcohol or tincture of calendula. Place mandarin or orange peels in water, leave for 1-2 days, and then sprinkle the culture with infusion.

Grate 1 teaspoon of soap, pour in hot water. Then add water so that the result is 1 liter, pour another 1 tbsp. a spoonful of alcohol or 2 tbsp. spoons of vodka. Cover the soil in a pot with something, and then soak a cotton wool in a solution of alcohol, collect all the pests, change the cotton wool from time to time. The next day, rinse the culture with warm water. And after 3-4 days, repeat the treatment.

Mash 25-70 g of garlic, pour in 1 liter of boiling water, leave for 6 hours, and then wipe the indoor culture with a brush soaked in the infusion. Do it in the evening. Next, cover the plant from the sun for 2 days.

Pour in 2 tbsp. tablespoons of olive oil in 1 liter of water. Wipe the entire plant with a dampened cotton swab.

Collect the horsetail herb, dry it, chop it, pour 4 teaspoons of the herb into 0.5 liters of boiling water. Leave for 20 minutes. Strain the infusion, spray and water the culture with it.

Mealybug on an orchid: treatment

Orchids are mainly attacked by citrus and bristly mealybugs. The females of the bristly mealybug are reddish and covered with a whitish coating. Long hairs are visible behind their bodies. Males are greyish, they have transparent wings.

Healthy well-groomed orchids secrete substances that repel a variety of insects, including mealybugs. Therefore, a mealybug appears on an orchid if the plant is sick.

Mealybug, how to deal with houseplants?

Then grate dark laundry soap, pour it into the settled water and mix. Next, carefully wipe the leaves and stems of the orchid with the resulting foam. At the end, process the culture blue vitriol or other fungicide. It is required that fungicides do not fall on the ground.

Violet disease control methods

Mealybug on violets appears for the following reasons:

  • movement of pests from newly acquired crops to old ones;
  • use of pest-infested land;
  • excessive fertilization with nitrogen;
  • lack of moisture.

Pour the flowerpots with boiling water or a bleach solution. Treat all the cultures standing nearby on the windowsill. In addition, wipe the shelves and window sills with bleach and alcohol. All this is required to be done by wearing disposable gloves, it is better to burn them then, and then wash your hands with soap and water. Spray plants with Aktellik, pouring 2 ml into 1 liter of water. Then do it again a week later.

You can water the earth in a flowerpot with Aktara's solution by adding 1.4 g to 2 liters clean water. Then sprinkle the violet itself. Then wait 1 month and repeat everything again. Or apply Phosphamide, it enters the culture in solution, and after that the insects sucking juices are poisoned and die. Wear a respirator to work with pesticides.

Pest prevention at home

Regularly carefully inspect the indoor flower. The mealybug is afraid high humidity and loves dry soil.

Properly care for the plant, cut off the yellowed and dried foliage. Rinse the plant regularly in the shower to wash the dust off the leaves.

Mealybug(felt) is an insect from the family of Hemiptera, belonging to the superfamily of worms.

Felters reach a wide variety of sizes, from small (3-6 millimeters) to medium (7-8 millimeters). In males, the body is much more developed than in females. The female usually has an elongated oval-shaped body, covered with powdered wax. At the time of laying eggs, the female hides in a cotton-like or saucer-shaped egg sac.

Science knows almost 500 species of felters that can lay eggs. This number of insects capable of producing offspring occupies ¼ of the fauna in the whole world. Among them, there are many individuals that can harm not only plants, but also humans.

It is customary to refer to worms as those insects that are in the suborder of coccids and unite more than one family. These include parnoglandular, giant, mealybugs, lamellar and felt. All these representatives of the suborder are the closest relatives of the scale insects. These insects are considered pests of many plants. Worms can strike different types citrus, palms and grapes. They pose a great danger to houseplants. Among them are an orchid, palm tree, dracaena, money tree, fuchsia, monstera, varieties of ficus and cactus, phalaenopsis orchid, violet and others. Felters can settle on various parts of the plant, ranging from stems and leaves, and ending with ovaries and fruits. If these insects "settle" on indoor plants, then the flowers will begin to grow and develop much more slowly.

Indoor flowers are the decoration of any apartment. They make the home more comfortable, as if they “revive” it. Some varieties of indoor plants bloom for a long time. These representatives of indoor fauna include orchids that bloom for more than 6 months a year.

More detailed information you can find out what other varieties of worms are in the next section of the article.

Varieties of mealybugs

There are more than 2200 varieties of mealybugs that inhabit Europe. People called these harmful insects "hairy lice."

The female adult insect and her larvae can suck the juice from young foliage, shoots and flowers of house plants. Varieties of citrus mealybugs can harm the root system. Adults and small individuals can move quite quickly.

Insects of the same species may have two different genital organs at once (sexual dimorphism). Males have the first pair of wings, well-developed limbs, and two tail filaments on the abdomen. Males do not have a mouth, as adult males do not feed on anything. In some species, the legs are poorly developed or absent.

Female felters usually have a mouth with which they suck the juice from plants. Many females are capable of laying eggs, and some are viviparous. The egg clutches of the female are placed in a white outer pouch that resembles cotton wool. Many species are capable of producing large offspring (2-4 generations per year). They can move quite quickly along the flower, which serves as food for them. Before laying eggs, some species of females leave their "familiar" place for a new one, looking for another shelter.

The larva of the first age is called a tramp. She can move very quickly through a room flower, which is of great interest to an insect. The wind can also be a carrier of harmful insects. When the larva of the mealybug sticks to the flower, its mobility noticeably weakens. As a result of molting, moving to the next age, the larval insect begins to look for a new habitat.

Worms live all over the world. But most of them are in tropical countries. Most often, they affect fruit (all types of citrus), technical (oil, spinning, medicinal, sugar and starch) and ornamental crops growing in squares, parks, gardens, greenhouses, recreation areas and on window sills.

The most famous greenhouse lamellar insects are:

  • grooved Australian;
  • bristly;
  • bamboo;
  • grape;
  • seaside;
  • root;
  • citrus.

Let's take a closer look at some of them.

  1. Seaside felter. This type of worm is the most common. Males and females have some differences. The body size of males is much smaller than that of females. Males can fly and move from one plant to another without damaging it. Females, on the other hand, are noticeably larger than males. Their body can reach about 4 millimeters in length. The legs of the females are strongly developed, and the body has a white or white-pink coating. During their lives, female individuals of this species can lay eggs in a kind of egg sacs. Females try to hide them in every possible way in the most inaccessible places of flowers, such as the axils of foliage, among shoots, as well as in the bark of some varieties of ornamental plants. 30 days after the larvae hatch, they begin to fully suck the juice from the flower. This leads to the destruction of the fruit or ornamental plant.
  2. Bristly. These individuals outwardly resemble seaside mealybugs, but have some differences. Firstly, they are much smaller - only 3 millimeters per dyne. And secondly, the females of these species are viviparous, not laying eggs. Individuals of bristle bugs mainly live in numerous groups and hide in hard-to-reach places in the plant. They can be shoots, bulbs and even roots.
  3. Grape. The appearance of this insect resembles the first two species. The female grape felters are oviparous. settles this species colonies similar to the first two species. The settlement of insects causes severe harm to a houseplant, drinking all the juice from it. The foliage on the flowers begins to turn yellow, and the shoots dry out. In place of the mucous secretions of insects, a fungus is formed.
  4. Citrus. Adult females of this species grow up to 4 millimeters in length. Their body is usually light pink, which has a coating. These pests can infect citrus fruits such as lime, orange, lemon, tangerine, grapefruit, pomelo and others.
  5. Root. The females of the root mealybug are white in color and reach up to 2 millimeters in length. hallmark of this species is that its representatives live in the roots and aerial parts of plants. Pests feed on roots and foliage, as well as sprouts or flowers. The ideal conditions for the life of these insects are dry and loosened earth. As a result of this “neighborhood”, many types of cacti that grow in this particular soil are regularly attacked by felt.

Plants and soil must be properly cared for. Do not add a lot of fertilizer, because this can lead to the reproduction of mealybugs. You should pay attention not only to the leaves and shoots, but also to the flower buds. Since the latter are saturated with nitrogen fertilizers many times.

Favorable temperature for the reproduction of insects is + 25-27 ° С. In a short time, a huge number of larvae appear from the clutch of eggs. Uninfected indoor flowers have good immunity. They are able to produce a special protective substance that repels mealy aphids. But these protective mechanisms in the plant work only in the warm season. In winter, metabolic processes fade away. This is because the days are getting shorter. Plants don't get enough light. Due to the centralized heating system, dry air is generated in the room.

For this reason, many indoor flowers become lethargic and weakened. Dry air contributes to the appearance of various pests on a weak plant.

Why is an insect dangerous for humans and plants?

Why is this insect dangerous for plants and people? This question can be found on various forums on the World Wide Web. In this section, we will look into this issue in more detail.

If you do not fight the worms and do not get rid of them in time, then the plant may die. Some species of females do not need males to reproduce. A separate subspecies of females produces offspring without laying eggs. Females can already produce actually full-fledged larvae, which may well immediately live and develop independently.

Most often, this insect affects the foliage and shoots of garden, home and office plants. Many varieties of citrus, orchids, gerberas, fuchsias, asparagus, cacti, oleanders and palms are at risk. The grape plant, palm tree, phalaenopsis and hibiscus can also be severely affected. The flower can die from the poison that the worms secrete. The orchid is more susceptible to the action of toxic substances. The infected plant changes color, and the foliage on the flower falls off. On a sick orchid, both the bud and the blossoming flower suffer. Due to the active reproduction of pests, young shoots of this beautiful flower are deformed. In violets, the root system becomes infected.

Felt is able to secrete a lot of sweet liquid that attracts ants. They find a home near the affected plants to protect hairy lice from other insects.

Like other members of the insect order, worms are carriers various diseases and viral infections. They can harm greenhouse, ornamental and agricultural crops. It is for this reason that insect pests are dangerous to humans.

Adult females are almost motionless, but they are still quite capable of infecting neighboring plants. Since many larvae can be carried by the wind, nearby fields and lands are at risk.

To prevent plants from suffering, you need to know how to deal with pests and get rid of them once and for all. What you need to do can be found in the next section.

How to fight at home?

How to deal with mealybugs at home? This question is very relevant not only for the owners of indoor plants, but also for many summer residents.

First of all, harmful insects must be eradicated correctly. Some believe that just getting rid of the affected flower is enough for the worms to disappear. But this is far from true. Most effective method Pest control is insecticide control. Only in this case it is necessary to approach the destruction of insects very competently.

Worms are not as tenacious as it might seem at first glance. Therefore, the plant can be treated with almost all insecticides. It is only necessary to ensure that the poisonous drug gets on harmful insects. In just 1 week, larvae emerge from the eggs. For this reason, it is necessary to start the fight twice - against adults and their offspring. The procedure should be carried out for two weeks in a row.

The main problem is that in the bags in which the females lay their eggs, reliable protection is created against the penetration of various poisons. There are no drugs that can simultaneously dissolve clutches with eggs and cope with harmful adults. For this reason, it is necessary to exterminate insects with the help of systemic preparations. They are well absorbed by plants, so insecticides can penetrate deep into the flowers. After drinking flower juice, insects receive a lethal dose of poison.

If the plants are not very affected by felters, then it will not be difficult to defeat the insects. For these purposes, it is necessary to stock up on a brush with soft bristles or a cotton swab, which is moistened in soapy water. Then it is necessary to clean the plant from insect pests and their whitish waste products. After that, three stages of spraying are carried out. soapy water taking a break every 8-10 days. For these purposes, you can use green soap, tobacco or garlic infusion, as well as a decoction of cyclamen. It is very good to treat the plant with alcohol or with tincture of pharmacy calendula.

If harmful insects hit the phalaenopsis orchid from the inside, then this greatly complicates the situation. You should not try to climb into the axil of the plant on your own, as these manipulations can damage an important organ of the flower. For an effective fight, you can use ordinary tweezers. If it is necessary to remove insects from young foliage, then it must be very carefully unfolded, and then cut off from the stem. The indoor plant will not suffer at all from this “operation”, but rather the opposite.

As "orderlies" of the forest, nature has created some types of insects that feed on mealybugs. Natural healers can be the gummy fly, the common goldhead, or the larvae and adults of Cryptolemus. With this biological method of struggle, microbiological preparations are used - lepidocides. Most often they are used in greenhouses or greenhouses. Australian ladybugs act as liquidators of harmful insects.

About what else by chemical means you can get rid of the "hordes" of worms, you can read in the next section.

By chemical means

Except biological methods pest control of indoor plants, there are also special chemicals. The range of drugs is very extensive.

Many gardeners and amateurs are well informed about such chemicals, which will be discussed in this article. In any case, let's dwell on this issue in more detail.

What drugs can be used:

  • Duntop;
  • Mospilan;
  • Aktar;
  • Confidor-maxi.

All preparations are prepared as follows. Every gram chemical agent diluted with 1 liter of liquid and watered with the resulting solution decorative or cultivated plants. Do not deprive attention of those specimens on which there are no "settlements" of the mealybug yet. If a decorative culture infected very much, then you can spray it once a week with any of the described drugs. To enhance the effect, you can alternate different chemicals to find the most effective.

There are several types of chemicals:

  1. Systemic ("Ifosfamide" or "Rogor"). Their contents fall directly into the juice of ornamental and domestic plants. After the drug reaches the "destination", the stems of the flower will contain poison, which is dangerous for felters.
  2. Intestinal ("Aktara", "Fitoverm" or "Nurell-D"). These drugs penetrate the insect first into the mouth, and then into the body.
  3. Contact (Spiruzit-aeschadlingsfrei). This type of chemical agent is absorbed into the body of an insect through the skin. The plant treated with this preparation should not be exposed to direct sunlight. After using this chemical, re-treatment of indoor plants is not required.

Before using any of the drugs, you must carefully study the manufacturer's annotation. It usually details the necessary doses, as well as methods of application. Do not deviate from the instructions and independently increase or decrease the dosage.

It should be remembered that certain types of drugs may contain toxic substances that are very harmful to humans and pets. Therefore, in order not to get burned or poisoned, put on your hands rubber gloves, and carry out the procedure on fresh air. At the time of spraying, limit the contact of pets and young children with a pollinated flower. It is advisable to first test the drug on a small part of the plant. You can spray some ready-made solution on the foliage, and then wait 1-2 days. If during this time nothing unusual happened to the flower, then the whole plant can be safely treated with the chemical. If wilted or yellowed leaves are found, the drug must be changed to another.

Observe the exact interval between treatments. It should be no more than 7-10 days. In order not to forget about this procedure, make the necessary note and keep it in a conspicuous place. The chemical acts only on adults, and the drug does not cause any harm to the larvae. If re-treatment with insecticides is not carried out in time, then all the offspring that hatch from the eggs from the moment of the first treatment will be able to re-attack the diseased plant.

The optimal time for the procedure is the period when the larvae on the infected flower have just hatched from eggs or left the mother's womb. Since the body of young individuals is very vulnerable and is not protected by special white wax, you can use this moment for a chemical "attack".

Due to the fact that several generations of worms live on indoor plants all the time, it can be very problematic to fight them. It is necessary to prevent the transition to a new stage of development - from a larva to a more adult individual. In this case, the advantage will be clearly not in favor of insects.

In addition to the preparations described earlier, there are also special sprays and granules. You can also purchase a special stick for the root system. Before using these means of "retaliation", you must carefully read their composition. This is worth doing because the root part of some varieties of indoor flowers is sensitive to fertilizers and various salts contained in a particular preparation. Therefore, for particularly capricious ornamental plants, you should not use the product in its pure form, but you can dilute it with water.

Change drugs periodically so that insects do not develop immunity to a commonly used type of poison.

Folk ways

To cure houseplants from a mealybug, you can not only use chemicals, but also remember the old folk ways of fighting, known to our grandmothers.

In this article, we have specially collected for you the most effective methods of struggle. Guided by advice experienced gardeners and gardeners, you can forget about harmful insects that have flooded your favorite orchids or violets, like a nightmare.

What can be used:

Product name

Method of application and dosage

Horsetail tincture

The plant is watered or sprayed with a ready-made pharmaceutical product.

Olive oil

2 large spoons of the product are diluted in 1 liter of water. Next, the flower is treated or sprayed with the resulting solution.

Denatured alcohol and liquid soap

It is necessary to take 10 milliliters of denatured alcohol and 15 grams of rare soap, and then dilute them with 1 liter of non-hot water. Ready solution you can spray a diseased plant.

Garlic tincture

5-6 cloves of the product crushed or passed through a press are poured with 0.5 liters of boiling water. Garlic water must be allowed to brew for 3-4 hours. Next, the tincture is decanted and applied undiluted to the foliage with a brush.

To achieve an effective result, experts advise repeating the procedure 2-3 times a week. You can not only spray the soil and the plant itself, but also treat the affected foliage with a napkin dipped in the special agent described above.

Prevention measures

Preventive measures against the mealybug are no less important than the treatment itself. They can be carried out during the off-season on very infected indoor plants, such as crotons, ficuses, succulents and various types of orchids.

What can be done:

  • keep the plant clean and remove all dried foliage;
  • inspect new flowers for harmful "lodgers" so that they cannot infect healthy houseplants;
  • when buying another plant, pay attention not only to the stems and foliage, but also to the root part, since larvae usually hide there;
  • do not leave a diseased flower unattended for a long time, as it can cause infection of other plants;
  • pests do not tolerate high humidity in the room and bright lighting;
  • periodically inspect all the plants in the house so that you do not have to wage a “full-scale” pest war later.

As you can see, the fight harmful insects It's not that easy, but it's still doable. Having received the necessary knowledge in theory, you can safely move on to practice. We wish you good luck!

Good day, dear friends! One of my good friends is very fond of indoor flowers. She has the whole apartment full different plants, she says they help her breathe by oxygenating the room. We agree with her, but when there are a lot of flowers, especially on the windowsills, it becomes dark in the room. Since they take away all the sunlight.

Decided with a friend to go to an exhibition in Botanical Garden, they just brought new variety ficuses and cacti, which she does not have. Entering the exhibition hall, I saw that she stopped at one cactus and began to examine it with different parties. It became clear to me that something was wrong with him. Lucy called an employee and pointed out the presence of a mealybug. He agreed with her and immediately removed the flower from the exhibition.

She knew what she was facing and told me what to do in such cases. In this article you will learn: mealybug - how to fight on indoor plants, the best drugs and folk methods, how to handle and basic precautions.

Basic ways to fight

To find a mealybug, you need to examine not only the stems or leaves, but also look at the shoots, ovaries of the plant. Pests can in large numbers be on the fruits, and in their inner part. They will have to be exterminated by a set of measures, which we will describe in detail below in the article.

Mealybug: how to fight on houseplants

If the infection with these insects has occurred in a mild form and has not yet been launched, then it is quite simple to overcome pests. You need to take a soft brush or cotton swab, dip it in soapy water, and then run it over all the infected places of the plant.

Next, you need to spray the plant 3 times in a row. The interval between procedures ranges from a week to 10 days. As an active ingredient, you can use a solution of green soap (prepared by adding 15 g per 1 liter of water), an infusion of tobacco, garlic or cyclamen.

You can do it easier by treating the plant with alcohol or using a pharmacy tincture of calendula.

When the infestation is severe, it is first necessary to remove all insects in the manner described above, however, spraying should be performed by special means. It is recommended to take sufficiently strong drugs that have a slight harmful effect on the plants themselves.

You can choose Calypso, Confidor, Tanrek, Biotlin, Confidant, Fitoverm or Mospilan. Sometimes it is necessary to try several drugs first, as there are types of mealybugs that not all remedies work against.

Folk remedies

Horsetail infusion. This tool works even in quite advanced cases. You can buy this drug at a pharmacy. It is marketed as a diuretic as well as a blood cleanser. Spraying with oil. It is necessary to prepare 2 tbsp. l. olive oil and place in 1 liter of clean water.

The entire composition is applied to the plant. It is recommended that it be sprayed, and not poured with oil, remember this.

Soap alcohol. To prepare this mixture, 10 ml of denatured alcohol and 15 g of soap in the liquid phase are sufficient. This mixture must be dissolved in 1 liter of water and sprayed on the plant. Garlic infusion. You should take about 5 medium-sized cloves of garlic and dissolve in water, which you need to pour about half a liter.

It is advisable to use these funds at a time when new insects are just hatching from an egg or have recently left the womb of an adult female. At this time, their surface is not yet fully equipped with a protective wax layer, so it is then that they are most vulnerable.

The mealybug is sometimes difficult to breed precisely for the reason that insects of different ages constantly live on plants.

If use chemical drug only once, then only young insect species are guaranteed to die, and new ones will hatch in a few days, since even after poisoning, old species retain the ability to reproduce.

When the larvae are already at a fairly high stage of growth, it is very difficult to overcome them. At the moment, there are many different chemical preparations on the market. The most popular of these are products in the configuration of sprayers and sprays.

When the drug is distributed throughout the plant, the solution is gradually absorbed and distributed in the internal fluid, that is, the juice of the plant.

Insects feed on it, and when the juice is infected, after drinking, they are poisoned, keep this in mind. The greatest effectiveness in getting rid of the mealybug is shown by preparations that, together with biological elements in the composition, include oil.

When using such means, a number of difficulties arise, since along with the poisoning of pests, the plant itself cannot be damaged. The funds should be carefully distributed to the immediate places of deployment of insects, as well as to the surface where they can presumably hide.

When sprays are used, precautions are also very important. First, you should study the instructions, which indicate the exact distance from the dispenser to the plant during application.

If you do not follow the manufacturer's recommendations, you can severely damage the leaves of the plantation. On sale there are special protective granules. Allegorically, they can be designated as root sticks. It should be remembered that these elements contain not only protective substances, but also special fertilizers.

Before using these tools, you need to test their composition. Some plant roots are extremely sensitive to the presence of salts in fertilizers, therefore, if negative substances get on them, they can undergo rapid and irreversible destruction.

Sometimes some drugs can be diluted with water to minimize the amount of salts, but this method should be used with caution.

To extract the worms from the axils of the leaves (and they sit very tightly, climbing deep into the stipules), you can use cotton swab soaked in alcohol, or soften the tip of a toothpick.

It is very important to mechanically select all pests before spraying with pesticides, i.e. by hand. If the plant allows, then wash off the colonies of mealybugs with a powerful pressure of hot water (45-50 degrees). And only then proceed to the treatment with drugs. Double action is most effective against worms, for example, watering with actara and spraying with actellik, karbofos, this is especially important for plants with leathery dense leaves.

If you have children at home, then it is better not to use strong-smelling products, but to spray and pour over a solution of any systemic drug: these are actara, tanrek, confidor or apache. Do not look at what is written on some insecticides: "from the Colorado potato beetle" - they successfully destroy the worms.

  • aktara from a mealybug: dissolve 4 g of the drug in 5 liters of water for irrigation and spraying;
  • tanrek from mealybug: 1.5 ml per 5 liters of water for spraying or 1.5 ml per 2.5 liters of water for irrigation;
  • Apaches for mealybug: 1 sachet (0.5 g) per 2.5 liters of water for spraying or 1 g per 1 water for irrigation;
  • confidor from mealybug: dilute 2 ml of the drug in 5 liters of water for spraying or 2 ml in 2.5 liters for irrigation.
After 5-7 days in hot weather or after 7-10 days, if it is warm but not hot, the treatment must be repeated.

A maximum of 3-4 treatments are used. The worms are very resistant pests, so the success of the cure depends on how carefully you clean them from the plant and evenly spill and spray the soil.

Mealybug: how to deal with indoor plants: prevention

Plants are carefully checked during the change of seasons, remember this.

Dried leaves are of particular danger if their damage has occurred in large quantities due to any violation. Regular washing of the plant should be carried out, taking into account dried areas if they cannot be removed.

  1. Inspect the plant regularly, and especially the underside of the leaves. Remove all dried, yellowed and deformed leaves;
  2. Periodically clean the leaves, stems and measles of the plant under warm running water with a soft sponge;
  3. Ventilate the room regularly, water and spray your flowers, as mealybugs love dry and stagnant air;
  4. Be sure to sterilize all components of the earth mixture before planting the plant in the resulting substrate;
  5. Quarantine new flowers after purchase. For 2-3 weeks, put the pot with the plant separately from the entire collection. Transplant it, change the soil, sterilize the pot and carefully inspect during quarantine.

Mealybug - what is it and why is it dangerous

A mealybug from the family of hemiptera scaly insects covered with powdery waxy secretion from the family of mealybugs. The mealybug is by far the worst and most widespread insect that can damage houseplants, greenhouse plants, and cacti and succulents.

Mealybugs belong to a huge group of insects, of which they make up about a third of the known species.

They are distributed throughout the world, except for the polar regions, and are one of the most economically important groups of insects, known to people because mealybugs attack many fodder and ornamental crops. Most mealybugs belong to the Pseudococcidae family.

The mealybug, a pest about 3 to 7 mm long that infects houseplants, is a soft-bodied, wingless insect that often appears as white cottony masses on leaves, stems, and fruits of plants.

Pests tend to congregate in large quantities, forming white, fluffy masses on plants.

They are covered with a whitish "powdery" coating that helps pests slow down the loss of water from their soft bodies. These pests prefer warm, moist, protected from harsh conditions and environment places of existence. Mealybugs feed by inserting their long mouthparts, called stylets, into plant tissue, sucking out plant sap in this way.

Various types of mealybugs prefer various ways Diet - Some species feed on the sap under the bark, some on the roots of potted plants, and others feed on fruits, flowers or seedlings. Adults are slow insects.

Adult females lay 300-600 eggs in fluffy cottony masses. Egg laying continues for about two weeks and females die shortly after oviposition.

Young individuals are born within 1-3 weeks, at the first stage they have no cover, they begin to actively move around the plant in search of food. As soon as the young mealybugs begin to feed on their own, they secrete nectar, which forms a waxy coating on their bodies.

Females go through three stages (ages in one generation) until they reach maturity. Reaching sexually mature age for pests depends entirely on temperature. Eggs may be laid singly or in groups by females, egg clusters are usually embedded in cocoons of wax threads.

Males go through five instars.

They do not feed after the first two instars and exist solely to fertilize females. In warm conditions favorable for pests, the continuous and incessant birth of new generations occurs during all year round.

Pest classification

Mealybugs are quite common pests on indoor plants - home conditions for them are just perfect for rapid reproduction - warm and dry. The worms do not like high humidity - this is not an obstacle to their reproduction, but wet air hinders the development of a colony of pests.

Almost all types of mealybugs look the same at first glance: white lumps, similar to cotton wool on the surface of the leaves, in the internodes, in cacti, entangle the stems with a dense cocoon. Single specimens, fattened and insolent, crawl right in the light:

  • The bristly mealybug Pseudococcus longispinus - females and larvae harm.
  • The body of an adult female is 3.5 mm long, oval, orange or pinkish in color, covered with white bloom. The worm has well developed legs, thanks to which they can easily move from plant to plant. The females are viviparous.

    They usually accumulate in the form of colonies on the underside of the leaf, on branches, in the axils of the leaves and on young shoot tips.

    The bristle scale insect is a fairly large insect, easily visible on the plant due to the white powdery coating that covers its body and white waxy formations in the form of cotton balls. The bristly mealybug most often damages lemon, laurel, oleander, cycad, fern, begonias, palm trees, dracaena, cacti, ficuses, asparagus, clivia, fuchsia, coleus, primroses, pandanus, etc.

  • Grape mealybug Pseudococcus citri - the body of a female is broadly oval, pink or yellowish in color, covered with a white powdery coating. The legs are well developed.
  • Males are very rare. Hatching larvae settle throughout the plant, on shoots, on leaves along the main veins.

    With a strong defeat, the worms form huge colonies that suck out all the juices from the plant. Grape mealybug most often affects aralia, figs, oleander, cacti, ivy, a coffee tree, gardenia, coleus, ferns, palm trees, amaryllis, jasmine, etc.

  • The Primorye mealybug Pseudococcus affinis is one of the most common species of mealybugs.
  • The body of an adult female is elongated-oval, 3-4 mm long, 2-2.5 mm wide, grayish-pink in color, covered with a white powdery coating. The legs are well developed. Males are much smaller, winged, fly all summer. Females lay their eggs in egg sacs, which are a white, fluffy, shapeless mass of waxy cobwebs.

    Usually oviparous females hide in secluded places: cracks in the bark, in twisted leaves, in the fork of branches.

    The larvae are small, mobile, yellow, completely devoid of wax coating. They quickly settle throughout the plant, are carried by the wind, humans and animals to other plants. The larvae turn into an adult insect in 1-1.5 months.

    The Primorsky mealybug most often damages: rhododendron, coleus, fuchsia, aralia, pelargonium, camellia, laurel, palm trees, cordilina, asparagus, ficus, cycad, citrus, begonia, cacti, oleander, krinum, etc.

  • Palm worm - the body of an adult female is wide, up to 2.5 mm long, covered with a wax shield in the form of cone-shaped cream-colored spikes.

Plants damaged by mealybugs suffer very severely and often irreversibly: the leaves turn yellow and fall off. Shoots lag behind in growth. The worms climb under the bark of citrus fruits and under the scales of bulbs in bulbous ones.

Sometimes the damage is so rapid that the leaves do not even have time to turn yellow - they dry out, become mummified gray. Sometimes a sooty fungus settles on the secretions of worms - black terry spots are formed, as if covered with coal dust.

At the beginning of infection, the mealybugs settle in the root zone, under the lower leaves, among the upper drainage in a pot, even in top layer earth. Gradually, they spread over the plant higher and higher. sunlight doesn't bother them at all.

Factors affecting the emergence and development of the pest

The development of mealybugs is completely dependent on temperature. Temperature within about 25°C and high relative humidity indoors are optimal for mealybugs and their numbers can reach a high peak in spring and autumn.

The damage done may not be great if you find the pest in time, and he does not have time to do much damage to your indoor flowers.

However, at higher numbers, the mealybug can cause the leaves to turn yellow and curl as the plant weakens. Damage to plants is usually accompanied by the appearance of a cottony coating, which makes the plant sticky and stimulates the growth of damaged areas. Mealybugs are a common greenhouse pest that affect ornamental plants, houseplants, avocados and fruits.

So, it is important to remember that mealybugs can reproduce by laying eggs very quickly under a cotton pad. Last years these pests quickly become resistant to pesticides.

  1. Mealybug can appear on your houseplants from pest eggs brought along with non-sterilized earth mix in flower pot;
  2. Soft and light insects are easily carried from place to place by the wind. Therefore, pests often enter the room in this way through opened window;
  3. But the most common way is to move mobile insects from the affected plant to healthy ones. This can happen if a new flower is placed immediately after purchase next to other plants.

Symptoms of a mealybug infection

Already on initial stage Infestation, you can see individual pests with a cotton-like waxy coating. But the mealybug can be on the underside of the leaf, making timely detection difficult.

  • the stems and leaves of indoor plants are covered with sticky sugary secretions ('honeydew', 'nectar'), shapeless silver or gray spots appear;
  • nests with laid eggs appear on the surface of the plant - fluff, wax threads collected in a bundle;
  • individual parts of the plant look deformed, dry, young stems and leaves become small;
  • weakened and prone to infection with various infectious diseases, the plant begins to rot, leaves and buds fall;
  • white spots and plaque appear on the roots of a potted plant (detected when a flower is transplanted).

Some flower growers manage to get rid of the mealybug, but in most cases, unfortunately, the plant cannot be saved. In fact, the waxy and fluffy coating of the mealybug makes it difficult for insecticides to penetrate the insect.

Mealybugs, also for a long time can be in a state inert material and become viable when conditions become favorable for them.

More often manifested by such signs:

  1. Mealybug nests look like a bundle of small wax threads (fluff, cotton wool).
  2. Infected plants stop developing, have poor appearance with a distorted stem and grow deformed, starting to dry out.
  3. The leaves become smaller, colorless and fall off prematurely.
  4. Weakened plants often begin to rot, being exposed to bacterial fungi carried by pests.
  5. A separate species of mealybug damages the roots of cacti.

  6. Damage - white spots on the root system, which can only be detected when the plant is transplanted. If the plant is sick and not growing, for an inexplicable reason, remove it from the container and carefully inspect the roots.

Damage to plants

Most houseplants are susceptible to these pests. They are especially common on rubber-bearing ficuses (elastica Robusta, for example) or Benjamin (Kinki, white De Gantel), on home azalea, napoinsettia (Christmas star), on anthurium, on spathiphyllum, on Hamedorea palm, on dwarf lemon tree, on asparagus, on uzambar violets (saintpaulia), on amaryllis, on clivia and hippeastrum.

Mealybug can even appear on prickly cacti and many other domestic succulent species (Schlumbergera zygocactus, euphorbia euphorbia, aloe agave or vera).

  • pests pierce the skin of leaves and stems, actively suck out the juices of the plant, greatly depleting it;
  • feeding on plant juices, the pest secretes saliva with enzymes that slow down the processes of photosynthesis and metabolism;
  • parts of the plant damaged by the worm are deformed, ugly spots appear that reduce the decorative value of the flower;
  • on the honeydew secreted by the pest, sooty fungus (black fungus) actively develops;
  • an exhausted plant becomes very susceptible to a wide variety of infectious diseases that can quickly destroy an indoor flower;
  • some species of mealybug affect root system plants, after which the roots begin to rot.

Have you, as flower growers, faced any really tangible danger? This is not aphids and spider mite. The most serious threat to your houseplants is the mealybug on houseplants. Don't eliminate it in time, and in a matter of weeks your favorite flower will be literally destroyed.

The thing is that mealy worms do not stop until they completely devastate the plant, so after themselves they usually leave a herbarium. How to proceed in such a case? The mealybug is a rather large insect related to the scale insect. Its appearance is almost immediately noticeable, in addition, an adult reaches 8 mm in length.

If we talk about the structure of the body, then in males of this species it is more developed, while in females it looks more like an oval-shaped larva than an adult representative of a mealybug.

Females mainly lay their eggs in special sacs located in the axils of the leaves. The presence of this pest is already noticeable, if only because a sticky white wax coating forms on the shoots of your plant.

They actively use their oral apparatus to pierce the surface of a leaf or bud, and then simply suck the juices out of them.

Moreover, they are able to do this long enough for the plant to begin to dry out. Young ladies can cause particular harm, as they are extremely mobile and require serious “food”. As for mature males, their oral apparatus atrophies over time, and they stop drinking vegetable juices.

Signs of plant damage

  1. The flower almost stops growing.
  2. All this happens because all the juices are literally drunk from it, so the flower develops fully, on the leaves and shoots of which dangerous pests, can no longer.

    In addition, it seems to be covered with a white veil or snow. In this case, you can be sure that the mealybug is already actively feeding on your houseplant.

  3. With indoor flower leaves and petals fall.
  4. For example, worms appeared on dracaena. In this case, the leaves of the plant are covered with a sticky substance that gives them yellowness. But this is only the initial period. Everything will end with a gradual death and falling of leaves.

  5. Runaways are deformed.
  6. It also happens under the influence of pests. Not only shoots, but also flowers change their shape, and this is the first signal that the situation with worms is aggravating.

    For example, if a mealybug settles and develops on money tree, in places where branches grow, white fluffy lumps appear. In the future, they will turn into whole fungal growths.

As soon as you encounter a mealybug on houseplants, take action immediately. The effectiveness of the measures taken by you largely depends on how prompt the measures taken by you are.

Preventive actions

It is quite difficult to get rid of the mealybug completely. The best option will be prevention. Such measures, of course, are not always necessary, but are recommended if you want to maintain the integrity of your indoor flowers.

Also try to maintain adequate moisture levels by regularly moistening the soil of the plants, as well as spraying them (however, only if the moisture on the leaves will not cause any harm to your flowers). If you still notice several individuals of insect pests on a flower, you should not immediately buy store funds.

First, treat the stems and leaves with concentrated soapy water. For periodic application, a mixture of tobacco and garlic is suitable. It repels a variety of pests, including mealybugs.

Effective methods of struggle

Use effective home methods, for example:

  • Herbal tinctures.
  • For this, calendula or horsetail powder purchased at a pharmacy is suitable. This composition does not differ in special preparation technologies, it is enough just to pour 100 g of dried herbs in 1 liter of boiling water and wait for the solution to cool. After that, apply it to the plants.

  • Garlic tincture.
  • The crushed head of garlic is also poured with water and left to infuse for 4 hours. When the composition is finally ready, soak a sponge in it and apply it on the trunk and leaves of a houseplant.

  • Oil emulsion.
  • 2 tbsp. l. add olive oil to 1 liter of water and mix thoroughly. This liquid must be sprayed with insect-infected plants.

  • Soap and alcohol solution.
  • 1 tsp grated soap and 1 tbsp. l. ethyl alcohol is diluted with 1 liter of water. The resulting composition is poured into a spray bottle and then sprayed onto the affected areas of plants. At the same time, avoid getting the liquid directly on the substrate.

    The procedure can be repeated if desired, but not earlier than after 3 days. In addition, a day after applying the solution, you must thoroughly wash it off your flower.

  • Lemon and orange peel.
  • You will need citrus peels. They must be poured with boiling water and leave the composition for a day.

Insecticides - how to help

Chemicals with a combined effect (for example, Confidor) - The best decision for those who have been fighting with worms for quite a long time, but do not get tangible results. In addition, if such pests not only settle on the surface of the plant (leaves, shoots and stems), but also surround its root system, only store preparations will help you.

What is special about professional insecticides? They penetrate inside the plant and, thus, after treatment, the insects begin to feed on the poisoned juice and quickly die.

Remember that repeated treatment with such drugs is a mandatory procedure for you, since no matter how potent the remedy is, it will not be able to destroy the eggs and larvae of mealybugs. Carry out a significant fight against such pests, and the result will not be long in coming.

home remedies

I would like to believe that pests such as mealybugs will not encroach on your indoor flowers. If trouble comes, in the form of a mealybug, I hope this article will be useful to you.

  1. Running water.
  2. With a damp soft brush, clean the plant from pests. Next, wash it under running water, paying particular attention to the reverse side of the leaves.
  3. Soapy-alcohol solution.
  4. Soap - alcohol solution is prepared as follows: you need to cut one teaspoon laundry soap and dissolve it in hot water. Next, add water to a volume of 1 liter and add 1 tablespoon of alcohol or two tablespoons of vodka to the solution.

    It is necessary to spray the plant with this solution, but before spraying it is necessary to close the substrate in the pot.

    The next day, you need to wash the plant with warm water. This treatment is carried out every 3-4 days. You can not spray the plant, but periodically dipping a cotton wool into the prepared solution to collect pests, and be sure to change the cotton wool so as not to spread the mealybug.

  5. garlic solution.
  6. Garlic solution can also help in pest control. To do this, take 25-70 grams of garlic and knead it, then pour 1 liter of boiling water and leave for about six hours. After a while, the solution is filtered and sprayed on the plant.

  7. Tincture of calendula.
  8. With a brush soaked in tincture, the area affected by the pest is carefully treated.

    This procedure should be done in the evening for 2-3 days, the plant during this period should be protected from sunlight. Tincture from citrus peels (orange, tangerine) should be infused for 1-2 days before use.

  9. Spraying with a jet of water.
  10. May help in the fight against mealybugs and frequent spraying with a thin stream of water. To make the insecticide stick better to the shells of pests, you can add a little dishwashing liquid. It is very important when treating plants to thoroughly moisten the most damaged areas.
