A spoiled crop, a lot of effort, time and money spent on the destruction of this parasite - no one wants to go through this.

Codling moth: getting to know the enemy
It is unlikely that the moth butterfly will attract your attention when it appears in the garden. After all, in appearance, it is so inconspicuous that it is absolutely not striking. Moreover, it is not capable of causing special concerns about its harmfulness. However, as often happens,behind the protective coloration lies a dangerous enemy of fruit crops. This is a rather large insect - the size of the codling moth butterfly is 18-21 mm in wingspan. The front wings of the butterfly are dark gray with dark wavy lines located transversely. Hind wings light brown. When a butterfly lands on a bark or branch of a tree and folds its wings, it becomes almost invisible.
To multiply, the moth flies out at night. Her departure occurs during the flowering of apple trees and lasts for 1.5-2 months. 1-3 days after the appearance of the moth plant, it lays on the leaves, shoots, fruits of the milk-colored eggs 1 mm in size.
One individual is able to lay 40-120 eggs. Further, white caterpillars with a black head hatch from them. With age, their color changes to light pink. It is the caterpillars of the codling moth that eat the ovaries, penetrate the fruit, leaving a wormhole.
In one season, the moth appears two or three generations. The greatest danger to fruit trees is the second.
Harm from moth
The moth harm not only the apple trees, plums, pears, quinces, apricots, and peaches also suffer from its vital activity.
The caterpillars enter the fetus through the stalked hollow, damages on the peel, under the cover of a leaf. In the place where the worm penetrated, rot appears. It is provoked by bacteria that carry caterpillars on their bodies. Later, damaged fruits are chosen by wasps.
Adult caterpillars of the last generation, crawling from one to another fruit, eat their flesh. Thus, one individual can spoil two or three fruits, and sometimes even five.
If a damaged fruit falls to the ground, within one or two days it moves from it to the trunk in order to continue its harmful activity in other fruits on the tree.
Now you have an idea of what a moth is and how much damage it can cause to fruiting apples and other fruit trees.
Further we offer you a description of several ways how to get rid of it. However, you need to understand that the use of one of them is unlikely to help you cope with the problem. Only an integrated approach is able to give the desired results.
Preventive actions
There are three ways to deal with the moth and its caterpillars in the garden plot:
- agrotechnical;
- biological;
- chemical.
It is necessary to get rid of plant residues, in which caterpillars can also hibernate. In early spring and autumn, the treatment requires bark of trees. Old sites, suspected locations of pupae, are subject to removal. The removed bark needs to be burned.
Do not ignore the drop.It is necessary to select more often.
It is possible to plant in close proximity grassy plants that attract insects - natural enemies of caterpillars. Also with the help of equipment feeders in the garden attract insectivorous birds.
Butterflies can not stand the smell of tomatoes. Therefore, you can scare them away from the garden by planting tomatoes or mustard, dill nearby.
In the summer you can use it as protection against the mothbread. trapping belts. They are made as follows. Stripes of 25-30 cm are cut from paper, cloth, burlap. They need to wrap a tree trunk at a distance of 30-40 cm from the ground. Top trap tied with string. Do not attach below.
Caterpillars, making their way to the fruit in the trunk below, will fall into the trap. They will need to be removed and destroyed from there. Traps can be impregnated with tracked glue. If the tree is more than 20 years old, you can also coat the material or paper with betanaftol.
As a trap, you can use the usual sticky tape for catching flies. Inspection of trapping belts is desirable to produce at least once a week.
Butterflies can be caught manually. As they fly out at night, they are attracted by the bright light, and then they are caught and destroyed. Under the light source, you can arrange a trap with adhesive tape or sticky paper.
After collecting the fruits, the containers where they are stored are covered with corrugated paper. Caterpillars leaving the carrion will fall into it. Containers should be without gaps, tightly closed. Subsequently, the caterpillar paper is removed and burned. A container from under the apples is cleaned and treated with boiling water.
Folk methods of struggle
Over the long years of confrontation with the moth on an apple tree, gardeners have tried many methods of struggle, including folk remedies. The most common spraying infusions and decoctions of insecticidal herbs: tansy, burdock, wormwood. Processed coniferous, tobacco broth. These tools have a deterrent effect.
The first spraying of infusions and decoctions produced when the apple tree blooms. Subsequent two treatments are at two-week intervals. Spraying is carried out in the evening in windless dry weather.
Tobacco decoction prepared from a pound of dry tobacco. It must be infused for 10 days in 10 liters of water. After boiling for two hours. After the broth cools, another bucket of water is added to it. Immediately before use, 50 g of soap is added to the solution. Trees are treated during the mass birth of caterpillars.
Also effective against moth is decoction of red pepper. It is prepared as follows. Take a pound of pepper pods, pour 2 liters of water, boil for an hour in a saucepan with a lid. Then the broth insist for two days. After that filter.
For spraying, use half a liter of broth, combined with 10 liters of water and 50 g of soap. The remaining liquid is stored in a closed bottle.
Its scaring properties are known and tomato infusion. For its preparation use 4 kg of chopped tomatoes (tops, roots, green fruits), 10 liters of water. The solution is boiled for half an hour, then filtered. For spraying, take 3 liters of prepared liquid, 10 liters of water and 50 g of soap.
Moth chemical preparations
Chemical preparations are used only in the case of mass destruction by codling moth.When spraying apple trees from the moth, you can find out with the help of the pheromone trap, which must be placed on the garden plot. If more than five butterflies fall into it within a week, it means that we cannot do without chemical treatment of trees.
Of course, it is advisable not to bring the situation to the point where it is necessary to apply chemistry. Use at first sparing methods of struggle. If they did not help, then choose the most environmentally friendly drug.
For severe infections, four treatments are recommended. The first spraying should be carried out during the departure of the butterflies, the second - in two weeks, the third - two weeks after the previous one, the fourth - after the harvest.
There are many drugs that can destroy the caterpillar caterpillars. Chemical, biological and viral agents have been developed.
Such insecticides, such as "Atom", "Binom", "Ditox", "Zolon", "Fufanon", "Sirocco", "Iskra-M", "Decis", etc., are most often used for moths. They are able to kill caterpillars in the period from the release from the egg to the introduction into the fetus. It is during this period that they need to process the trees.
Anti-moth use allowed pyrethroid drugs: "Ivanhoe", "Calypso", "Sumi-alpha", "Kinmiks", "Fatrin", "Alatar". This group is used for processing 8-10 days after the departure of butterflies.
In the fight with moths use growth regulators "Dimilin", "Match", "Herald", "Insegar".
From biological preparations effective "Fitoverm" (used in the period from the release of caterpillars from the eggs until they fall into the fruit); "Lepidocide" (during the growing season against each generation, adhering to the interval of 10-14 days), "Bitoxibacillin" (during the growing season against each generation with an interval of a week).
Viral drugs use less often. Allowed: "Madex Twin", "FermoVirin YAP".
