Abstract. The research aimed to develop methods for the synchronous regulation of the main apple pests’ abundance using interspecific pheromone sources. The work was carried out in the Krasnodar Territory in an apple orchard on an area of 5 hectares. The garden was founded in 2015 with planting pattern of 5 m x 2 m; the tree crown formation was spindle. To study the species composition and dynamics of the population of apple pests, standard pheromone traps Atracon and Atracon A were used. When developing methods for synchronous regulation, dispensers with pheromones of the studied species of apple (Cydia pomonella L.), plum (Grapholitha funebrana Tr.), and oriental (Grapholitha molesta Tr.) moth, as well as quince moth (Euzophera bigella Zell.) were placed in the trap at the same time. Most insect species from the order Lepidoptera were represented by the family of tortrix months: Torticidae – 72.6%, Noctuidae – 9.5%, Pyralidae – 4.8%, Sesiidae – 4.8%, Liithocolletidae – 4.8%. The plum (G. funebrana) and eastern (G. molesta) moths and quince moth (E. bigella) were the most widespread and coinciding in flight synchrony with the codling moth (C. pomonella). The plum moth pheromone stimulated the capture of the oriental moth. That is explained by the pheromone molecules that are similar in structure. This allows the joint use of pheromones in the development of synchronous protection methods. Traps with interspecies pheromones attracted a large number of non-target species of Lepidoptera; green oak leaf roller and other species of the families Torticidae, Pyralidae, Noctuidae were caught. It can be explained by the coincidence of structures formed during the emission of substances that are parts of the multispecies pheromone. The study results of intra- and interspecific chemical communication of insects serve as the basis for the development of methods for their biological control at the level of agrocenoses and agroecosystems.
