Apple codling moth wintering stage of development. Codling moth on an apple tree: effective methods of control. How do I treat my garden from codling moth

A good harvest is the dream of any farmer or cottage owner, but a large number of factors often work against it, these can be pests, diseases, and much more.

Pests can become a very dangerous enemy for almost any plant, one of the most dangerous pests, is a codling moth on an apple tree, the methods of dealing with which are described in this article.

What is an apple codling moth?

At first glance, the codling moth does not pose any danger, as it is a very small creature, the dimensions of which are usually between 18 and 21 mm. The codling moth looks like a small butterfly, it is active only at night, when it actually inflicts the most great harm apple tree. How can a codling moth harm an apple tree? The fact is that this creature lays small transparent eggs, the diameter of which reaches 1 mm. After some time, caterpillars appear from such eggs, which are actually the main pests of apples.

The main pests are caterpillars of the apple codling moth.

Despite their small size, these caterpillars are able to eat apples extremely quickly, in one season one such worm can damage about 5 fruits. If we take into account their possible number, then we can conclude that if you do not start a serious fight against the codling moth on the apple tree, then the entire crop may simply die, which, of course, no one would like. Therefore, if you find a codling moth on an apple tree, you need to urgently deal with its destruction.

Methods of dealing with apple codling moth

There are a considerable number of various methods and means, many of which are very effective and at the same time harmless to the apple tree itself and its fruits. Let's look at the most popular methods of dealing with codling moth on an apple tree.

Chemicals

One of the most frequent ways To combat the codling moth are all kinds of chemical agents that have proven themselves very well among farmers, as they are able to cope with this problem very effectively. Most popular among chemicals have organophosphates, big choice which can always be found in specialized stores. Most often, the following are chosen among the chemicals: Zolon, Atom, Binom, Tod, Sirocco, Calypso, Koragen, Dimethoate and many others.

Chemicals should be used only at the beginning of summer

best time for the use of such preparations is the period when the caterpillars only emerge from the eggs. When using such drugs, it is very important to strictly follow the instructions. For an apple tree, they are safe if all proportions are strictly observed.

In addition to following the instructions, it is also important to follow the necessary safety rules:

1. Chemicals should be used only at the beginning of summer, in the middle of summer it is better to use mechanical methods struggle with the codling moth on the apple tree.
2. If you plan to spend several chemical treatments apple trees, it is best to do this with different preparations.
3. Before processing all the apple trees in the garden, process only one of them and see what happens to it in a day. In the event that everything is in order with the apple tree you processed, you can safely proceed to processing the rest.
4. Do not forget to read the instructions carefully, and also use personal protective equipment.

Chemical methods of dealing with codling moth on an apple tree are very good and effective, but you can use not only them, but it is best to combine them with other methods.

Biological agents

Biological methods of dealing with codling moth on an apple tree are also very effective and can give a very good result. One of the most popular drugs is Fitoverm, and drugs such as Lepidocide are also very often used (it is better to use it in case of a massive invasion of caterpillars), as well as Bitoxibacillin (this drug should be used only during the growing season of the plant, while it is strictly forbidden to use it at the time of flowering ). You can buy such drugs at any hardware and farm store, usually their price is low. When using them, as in the case of chemicals, it is very important to do everything clearly according to the instructions and do not forget to use individual funds protection.

Bitoxibacillin is able to give a very good result in the fight against codling moth on an apple tree

Mechanical means

In addition to chemical and biological methods control of the codling moth on the apple tree, which are the most commonly used, there are also mechanical means of control, which can also give a very good result. TO mechanical means, include the following:

1. Cleaning apple trees from old bark, what is best to do in early spring, since the codling moth pupae can hide in it.
2. Digging up the ground around the tree in the fall can also help reduce the chance of moths.
3. Creation of so-called trapping belts on the tree trunk, which will not allow caterpillars to climb the apple tree. The trapping belts themselves are a small strip of burlap or paper (20-30 cm wide), which is wrapped around a tree trunk at a low height (40-50 cm), and fixed on top with twine.

Apple codling moth is one of the most common garden pests. Most often it affects apple trees, but in lean years it can also live on pears, plums, apricots, peaches. The fruits affected by the codling moth not only lose their marketable appearance, but also crumble, not yet ripe. It also carries viruses and bacteria on itself, thereby contributing to the development various diseases garden trees.

The codling moth hibernates in the bark, fruits and topsoil in the state of chrysalis. As soon as the apple trees begin to bloom, the first butterflies fly out, which after 7-10 days begin to lay eggs. After 4-10 days, caterpillars appear from them. It is at the larval stage that the codling moth is most vulnerable. But this period lasts only a couple of hours, and then the caterpillar hides in the fruits. If the damaged apple falls, the codling moth leaves it within 1-2 days and returns back to the tree along the trunk. The flight of butterflies lasts 1.5–2 months, and all the time they lay new eggs. As you can see, the period of greatest vulnerability of the pest is very short, and it is quite difficult to determine the exact time. That is why one of the most effective methods of dealing with apple codling moth is prevention:

• Remove old bark from trees to remove pupae. To avoid damaging the barrel, do this with a block of wood or a plastic scraper.
• In early spring or late autumn, dig deep around the trees. You can also additionally treat the soil layer with insecticides.
• Collect scavenge daily. Those fruits that you will not use for food, remove from the site or bury in the ground to a depth of at least 50 cm.
• Plant different flowering plants in the garden - this will attract insect enemies of the codling moth.
• You can also plant tomatoes - it is believed that their smell repels the pest.

So that the caterpillars from the ground could not get on the crown, place trapping belts on the boles of apple trees. To do this, take burlap, corrugated paper or glass wool and fold in 2-3 layers. Place the resulting bandage 15-20 cm wide on a tree trunk at a height of 30-40 cm from the ground and secure with twine. For a better "catch", bend the upper and lower edges of the belt outward. Periodically inspect the protective bandages and destroy the caterpillars. To increase the effectiveness of trap belts, they can also be moistened with insecticides from time to time. To catch apple codling moth butterflies in the garden, food bait traps can be placed. To fill them, you will need thick kvass, apple juice, sour compote or apple uzvar with the addition of yeast. Pour the liquid into a jar and place it on the trees growing near the apple trees. Good result give industrial pheromone traps. At the end of the flowering of apple trees, hang them inside the crown on the western side so that the end parts are facing in the direction of the main winds. It is especially important to place the traps at the correct height - ¾ of the crown. Make sure that the leaves do not block the access of insects to the device. One trap is enough for 2-5 apple trees. In the case of the development of a large population of codling moth, additionally treat the crown with insecticides. Effective drugs: Atom, Zolon, Dimetoat, Ditoks, Sirocco, Tod, Fufanon, Iskra M. Spraying is carried out during the period of mass appearance of caterpillars from eggs, that is, 10-15 days after the peak of the butterfly flight. During the procedure, you need to completely cover the leaves with a solution of the drug, Special attention give the top - this favorite place habitat of codling moth caterpillar. Spraying should be repeated after 2-3 weeks. To preserve the garden ecosystem, experts recommend repeating treatments with microbiological agents, and using chemicals only for the first time.

It is often problematic to carry out a full spraying of an apple tree, since the tree can be up to 8 m in height. That is why for industrial cultivation apples, preference should be given to undersized and dwarf varieties.

The codling moth is an insect belonging to the order Lepidoptera (butterflies). One of the most dangerous and widespread pests orchards. The larvae of these pests are harmful fruit crops: mainly apple trees, as well as pears, peaches, apricots, plums. Rare forms of codling moth develop in walnut fruits.

What does it look like

The apple codling moth (butterfly) has a wingspan of 17..20 mm, the front wings are elongated, the color is ash or brownish-gray, the wings are decorated with many transversely wavy stripes, a dark brown spot with a bronze sheen, the hind wings are grayish-brown in color.

Adult caterpillar 18..20 mm, color: pale pink from the back, abdomen and sides are yellowish-white.

Adult caterpillars hibernate on trunks, skeletal branches of trees, climb into cracks in the bark, under loose dead bark, or burrow into upper layer soil.

What harm do

Larvae - caterpillars of the apple codling moth, developing in fruits, eat the pulp and seeds. They begin to destroy the fruits for almost initial stage formation of ties.

One caterpillar damages one fruit, but in the case of a significant number of pests, garden culture often doomed. In one season, the apple codling moth usually hatches two generations of larvae, in the northern regions - one generation. Under favorable conditions for the development of larvae, they destroy up to 90% of the apple crop. The problem of getting rid of the apple codling moth pest is relevant for gardeners and orchards.

The method of dealing with apple codling moth directly depends on the growing season of the apple tree. May - early June, when the air temperature reaches +20 ºС, the first generation of butterflies appears. At this time, pest control is possible with the help of chemicals.

During the second and third laying of eggs of the codling moth, it is impossible to use chemicals, since pesticides can accumulate in the fruits, as a result of which they cannot be used for food, due to the risk of poisoning with pesticides.

Ways to fight

To combat the pest, the following means are used:

• Chemicals
• Biological agents
• mechanical way

Chemicals

For the treatment of apple trees from the pest of the codling moth, the following preparations are used: Decis, Kinmiks, Inta-vir, Fury, and for planting in vast areas - Fitoverm, Lipitocid, Agrovertin.

The apple codling moth usually begins a mass summer in the late afternoon, so the optimal time for spraying apple trees is in the evening with calm, calm weather.

When preparing a working solution, strictly follow the instructions, and when processing trees, make sure that all fruits and branches are properly processed.

Biological agents

• Infusions and solutions are effective remedies for combating codling moth, which you can prepare yourself. For example, an infusion of tansy, burdock, needles and wormwood. This infusion should be processed three times: the first time after the completion of flowering trees, the second and third times with an interval of two weeks.
• Plant plants: tomatoes, phacelia, dill, mustard, which will attract natural enemies of caterpillars - riders. Remove damaged pests from under the tree regularly and dig away from apple trees
• In winter, hang bird feeders, this will attract them, in spring the birds will help to destroy the bulk of the codling moth.
• Install pheromone traps, the essence of such a device is that a special female pheromone is applied to the trap, and males, attracted by the smell, flock within a radius of 50 meters.

mechanical way

Some preventive actions to control the number of codling moth:

• In autumn, after picking apples, dig deep trunk circles apple trees;
• In the spring, clean the tree of dry, dead bark where pupae can hibernate and burn it.
• Install trapping belts on the tree trunk, in the form of tapes with non-drying glue, which should be changed every few days.

Use these simple methods and the codling moth will not be scary fruit trees in the garden, you will be able to provide good harvest apples.

You need to know - all the ways to deal with codling moth

To call this insect "codling moth" would not be entirely correct. A representative of the butterfly family in the form of a small invertebrate destroys not only the fruits on the trees, but also destroys their green shoots and foliage. Then, as in a fairy tale, the ugly worm turns into a beautiful butterfly of a velvety gray color. This is the apple codling moth. It is problematic to see her, because. leads a nocturnal lifestyle. But the consequences of the vital activity of the larvae are noticeable: a spoiled fruit crop.

Stages of development

First a caterpillar, then a butterfly

Choosing fruit trees(apple, plum, peach), the butterfly Cydia pomonella after a few weeks lays eggs on the back (shadow) side of the leaves. Under favorable conditions, the offspring matures, so that in two weeks caterpillars (codling moths) of a bright pink color 1.8-2.0 cm long will appear. At first they absorb soft foliage. Having got stronger, after 5 days, they gnaw through apples. In them, the worm develops further, up to the moment of pupation (under a layer of fallen leaves). Then everything is simple: the chrysalis becomes a butterfly of the codling moth. It will help to consider in detail what the apple codling moth looks like photo.

Preventive measures in the fight against codling moth: traps

With a properly organized control strategy, pheromone traps for the codling moth will help to significantly reduce or completely dispense with chemicals. With their help, the pest population is monitored by counting the butterflies caught per week. If the result exceeds 5 copies, it's time to take action. The principle of operation is based on the effect of the female pheromone on the male. The trap emits an attractive smell. Males that appear in the spring before the "girlfriends" fly to him and fall into a trap. So you can catch most of the male codling moths who did not have time to fertilize the females.

Pest traps of various modifications are available in trading network. But for a home garden, it will not be difficult to make do-it-yourself codling moth traps.

• The cardboard box is disassembled.
• A three-dimensional triangle (prism) is formed. 3 sides of the structure are fixed with staples (construction stapler).
• At the top of the roof of the "house" with an awl, with a knitting needle, 1 hole is made in each part.
• Between themselves at the top 2 sides are connected by wire.
• The same wire is attached to a tree branch.
• A “trap” is being prepared: a special insert smeared with strong fixation glue from rats or mice. He will go crazy at the bottom of the prism (the base of the house).
• To attract insects in the absence of enzyme capsules, you can use sweet kvass or compote, poured into a small container.

This trap is good because other pests come across it.

Insecticides against apple codling moth

Most effective measures pest control - spraying with insecticides: poisonous chemicals protection of plants from insects. Held in mid-June and early July.

Adjustments are made by varieties of apple trees.

• For early ripening fruits enough 2 or 3 treatments.
• Autumn-winter varieties of apples require 4-fold spraying.
• Winter varieties are processed up to 7 times.

In other words, the fight against the codling moth with the help of chemical means of protection is considered the most effective in the period between the laying of eggs and the onset of damage to the fruit by caterpillars. To enhance the effect, insecticides are often diluted with fungicides (repellers). There are several processing methods.

• Dissolve a tablet in 10 l of water or in a 5-15 l ampoule of Sherpa (Arrivo, Proteus). Treat the tree for the first time in early June. Then twice at intervals of 14 days and the last time after the removal of the fruits. Usually, 3-4 treatments are sufficient.
• As insecticides are used: Ditox, Karbofos, Calypso, Fozalon, Karate, Zolon, Vantex, Bi-58, Accord, Fufanon, Gladiator, others.

Inta-vir is also used against the codling moth

A folk remedy for codling moth on an apple tree is camphor alcohol. Its pungent odor will repel pests. It is enough to hang a large number of rags soaked in a combustible substance on the branches.

Manual way to deal with codling moth

Without waiting for the activity of the pest, preventive work is carried out to prevent the development of the population in a manual (mechanical) way. It is quite effective in solving the problem of how to deal with the codling moth. It consists of the following:

• removal of lagging bark - caterpillar shelters for the winter;
• loosening the earth in the root zone and digging (plowing) the soil between the rows;
• pruning damaged branches, shoots;
• sealing cracks in wood, hollows;
• daily inspection of the greenery of the crown, collection of spoiled leaves and fruits;
• regular release of the site from damaged fruits that have fallen from the tree, their destruction;
• fixing trapping strips (belts) on trunks for catching caterpillars is an effective eco-friendly protection of apple trees from codling moth.

Pest control without chemicals

Processing apple trees from the codling moth in the spring with insecticidal preparations has reverse side: part of the poison is absorbed by the fruits. With repeated spraying, you can alternate chemicals with decoctions, tinctures.

• The garlic will do onion peel, hot pepper, green tomato sprouts. Pour 1 kg of fresh "raw materials" or a pound of dry grass boiled water. In a sealed container, leave to infuse for 48 hours. Boil the substance for 0.5 hours. Bring the volume up to 10 liters with water. The composition is ready for spraying.
• You can treat the apple tree from the codling moth immediately after flowering is completed with wormwood infusion. After that, it does not hurt to repeat the procedure three times within a month with an equal interval in time. For a deterrent effect, you can plant bushes of wild wormwood in the garden between the trees.
• Use apple cider vinegar as bait. One and a half liters of water will need a glass of it. Hang the mixture on the branches. Change as the container is filled with pests (every 5 days).
• Coniferous extract is prepared from filled with liter jar needles. This amount is poured with heated water (2 l) and kept for 7 days without air access. It is filtered. The resulting concentrate is diluted in a 20-liter container (barrel). Spray trees immediately after flowering.
• The codling moth on an apple tree is processed with chamomile infusion. Flowers are harvested fresh or bought in a pharmacy chain in a dry state. Raw materials need so much to get a strong concentrate. For pharmacy packaging: 1 pack of inflorescences per 10 liters of water.
• Wood ash is used in dry form (powder the tree, cultivate the ground near it) or as a tincture. One and a half cups of the substance insist in a 10-liter bottle for 24 hours. 0.5 kg laundry soap added before processing.
• In early spring, before the buds have blossomed, apply a saline solution to the apple tree (10 liters of water with 1 kg of dissolved table salt). This amount is enough for a fruit-bearing tree. If it is a seedling, two liters is enough.

Do not neglect the help of biological "helpers": earwigs, ground beetles, ants and ladybugs. No need to destroy their nests, populations. Remember your childhood and build a bird house. Natural garden nurses are a significant help in pest control.
