Abstract. In this article, the scientific basis for increasing the productivity of apples in orchards, reducing the costs of their cultivation, and reducing the amount of damage caused by pests and diseases was explained. In addition, the bioecological characteristics of the development of the main pests of apples were studied, and with the help of ways and methods of monitoring them, cypermethrin 25% em.c. When applied at 0.3 l/ha, damage to fruits is 17%, biological efficiency is 81.8%, and in the third option Endjeo is 24.7% sus.k. When 0.2 l/ha chemical substance was used, the damage of fruits was 9%, and the biological efficiency was 86.5%.

Keywords: apple fruit borer, sap, Carpocapsa pomonella eggs, worm, damage, generation, genus, pest, Avaunt, Entovant, chemical control, biological efficiency, economic efficiency.
