The aim of the research is to study the species composition and trophic specialization of entomophages to regulate the number of major soybean pests. The research was carried out in 2023–2024 in Krasnodar on soybean varieties Vita and Grant (2 ha), as well as in the Dinskoy (10 ha) and Korenovsky districts (15 ha) on varieties Vilana, Vilana Beta, and Veda in farms practicing Integrate Pest Management systems. The biopesticide Akkar, L (4 L/ha) was applied twice against the cotton bollworm and the pulse pod borer moth at 10-day intervals. The species composition and abundance of insects have been accounted by sweep netting (with entomological nets of various modifications) and setting the Malaise traps. Also various methods for mass and individual hatching of pests (cocoons, pupae or imagoes and host insect or its eggs are incubated together in isolated containers) have been used. The parasite complex of the cotton bollworm on soybean is represented by 43 species from the Ichneumonidae, Bethylidae, Braconidae, Encyrtidae, Elasmidae, Eupelmidae, Eulophidae, Pteromalidae, Torymidae, and Trichogrammatidae families. Seven species from the Coccinellidae family have been found on soybean crops, including 6 entomophagous and 1 mycophagous species. The trophic relationships of the main parasitic hymenoptera are associated with the pulse pod borer moth (Etiella zinckenella) at its different preimaginal stages. Two native parasitic hymenopteran species, Pediobius cassidae and Anastatus bifasciatus recorded in soybean crops are effective against adventitious species of stink bugs Halyomorpha halys and Nezara viridula.
