The paper presents the results of the study of the regulatory complex of the mealybugs species of the genus Pseudococcus, which overwinters in the trap belts of the plum crop. It was established that in the adult stage it is parasitized by 5 species of parasites, among them 3 encyrtids, 1 megaspilid and 1 sygniphorid. The highest number of females parasitized by Stemmatosteres bochemicus was recorded in the belts influenced by the apple culture adjacent to the plum. The sex ratio (♀:♂) of the polyembryonic parasite population analyzed was 2:1.

Several aspects (optimal distances placement, beneficial
hymenopteran’ families composition, used compound volume per season) of two
semiochemicals - phenylethanol and methyl salicylate’ attractiveness for beneficial
hymenopterans were discussed.
