“…With the advent of pheromones and modern technologies, which over a long period are dosed and regularly release volatile substances from dispensers, it has become possible to reduce the quantity of chemical treatments. Specifics of pheromones are -effective control of the phytophage population at an economically imperceptible level, selectivity of action, absence of toxicity for mammals and entomophages, as well as high efficiency with minimal amounts and rapid degradation in the environment [2][3][4][5].…”

In the region of Krasnodar Territory, Cydia pomonella L. belongs to the dominant pests of the apple tree, against which 8-10 treatments with insecticides are carried out during the growing season. In world practice, pheromones Shin-Etsu® MD CTT, D and BRIZ® are used in apple agrocenoses for the control of C. pomonella. abstention or reduction of insecticidal treatments leads to a decrease in the pesticide load on the agrocenosis of the garden by a factor of two or more. The objective of our research was to determine the biological pheromones effectiveness in controlling C. pomonella quantity. The test was carried out in two horticultural zones of the Krasnodar Territory, in areas with different numbers of phytophage. The experiment as a result, it was found that in the experimental plots the percentage of damaged fruits in the drop was 1.3-1.5%. Fruit damage wasn’t observed in a removable crop, which corresponds to the results of the standard version, with the use of insecticidal treatments. It was found that the pheromones usage in the Black Sea horticultural zone of the Krasnodar Territory is economically feasible. Сost reduction for the purchase of insecticides amounted to 9089.2 rub/ha, a decrease in pesticide load by 70%.
