The work represents the highlighting of the arthropod complex, which populates and hibernates in the cardboard trap belts of the plum orchard influenced by green manures and nectariferous crops. This complex is composed of phytophagous, saprophagous, predators and parasites. In the trapping belts, polyphagous species of five families of spiders dominated, which constituted an average of 33.5% of the total individuals highlighted, and coccinellids (seven species) - an average of 6.5%. The parasitoid Scambus inanis achieved a degree of parasitism of moth larvae in average 29.4%. The highest percentage was recorded in the standard and experimental variants (46.0% and 35.3%) respectively.

The paper presents the results of the study of the natural and laboratory trophic links of the invasive predatory bug species Amphiareus obscuriceps found in the trap belts intended to study the winter reserve of plum crop pests. The predator was offered eggs of different stages of embryonic development of whiteflies Aleyrodes proletella, A. singularis, obtained from the plum plantation; Acanthoscelides obtectus and Galleria mellonella eggs obtained under laboratory conditions. It was determined that the predator can suck in one day on average 40.2 eggs of G. mellonella, 26.1 eggs in the late stage of embryogenesis and 11.7 eggs of one day of A. singularis and 9.3 eggs of A. obtectus.
