ANNOTATION
Harmful and beneficial species are important in maintaining the natural balance. Among insects, there are not only harmful, but also useful species, which feed on plant pests. This creates biological control.
One of the pests is aphids, which damage various fruit trees and are considered one of the most adaptable species. These pests can feed on almost all fruit trees. The importance of birds in the protection of orchard trees is considered high. Migratory birds - nightingales, hummingbirds, swallows, long-winged and blue-throated warblers feed on insects throughout their lives.
Similar beneficial animals exist among mammals. But they are often killed as harmful.
Key words: pest, seven-pointed hawk moth, connected earring, golden-eye, scab, panatelas, sipukha, agro technic, shield, apple scab, chemical, bud moth, insect, species composition, bio ecology
INTRODUCTION
The biological method is aimed at eliminating, reducing or preventing the destruction of harmful types of insects by using parasites and predators of insects, as well as disease-causing microorganisms. Spider mites and other mites have many natural traps that limit the number of mites to a certain extent. These include trips, trips, etc. Golden eyes are bred in bio laboratories of Uzbekistan. The use of goldeneye against spider mites and other mites is effective. Plant pests cause damage to fruit trees and other agricultural crops, causing a sharp decrease in productivity. Beetles fly well, quickly find aphid colonies, feed and lay their yellow shiny eggs here in heaps, small black six-legged larvae also feed on aphids. A colony of aphids disappears in the place where it is hungry. The importance of birds and mammals in the protection of orchard trees is high. Migratory birds - nightingales, hummingbirds, swallows, swifts, and blue herons feed on insects throughout their lives.


MAIN PART
It is necessary to cut off the branches that are heavily affected by the pest and remove them from the garden. Male branches, which are not important for the harvest, are also cut in spring and summer, because aphids develop en masse in them. When aphids damage more than 60% of branches, it is recommended to use chemical control measures. It is most effective to spray oil products against wintering pests at the time of budding. Control measures are treated by mixing the means containing chlorpyrifos or diazinon with mineral oils at the time of budding. During the growing season, it is treated with preparations containing spirotetromate, thiocloprid, imidocloprid, acetamiprid or diazinon. This fruit growing is a new type and is also called fruit growing. At the present time, farmers and gardeners are more interested in early harvesting, easy maintenance, and mechanization of the main work processes in the garden after the garden is established.
Beneficial insects, such as gnats, syrphid flies, golden-eyes, and caterpillars, reduce the amount of sap.
