Goal. To analyze the phytosanitary state of vegetable agrocenoses of the Right-Bank Forest-Steppe of Ukraine, to establish the species composition of the dominant pests and to study the natural saturation with beneficial organisms. Methods. The collection of material and entomological observations were carried out in accordance with generally accepted methods. Variation-statistical analysis was carried out using special software packages for statistics and computer graphics: Microsoft Excel

... , Statgraphics plus. Results. By monitoring the phytosanitary state of vegetable agrocenosis in open ground, the species composition of the complex of harmful and beneficial organisms has been established. It has been proved that phytophages dominate on the plantings of white cabbage (variety Dymerskaya 7): black cruciferous flea beetle, numbering 8.2—10.8 ind./plant; cabbage spring fly — 9.0—11.6 eggs / plant; hidden proboscis — 2.6—3.1 persons/plant; onion thrips — 2.3—6.1 ind./ plant; cabbage aphid — up to 32 ind./plant and cabbage whitefly, the number of which was 2.5—6.7 ind./pl. The most common in the agrocenoses of white cabbage among lepidoptera were cabbage moth, numbering 2.8—4.3 gus./ plant, cabbage scoop — 1.6—1.9 gus./plant, cabbage and rape whites — 0.6—3.1 gus./ plant. Common spider mites dominated on cucumbers, with a number of 3.6—4.2 specimens/plant. and melon aphids — 14.8—16.6 ind./plant. A complex of entomophages belonging to the families Coccinellidae, Staphilinidae, Ichneumonidae, Trichogrammatidae, Braconidae, Tachinidae, Sirphidae was noted. Conclusions. The species composition of the complex of harmful and beneficial organisms in the vegetable agrocenoses of the open ground of the Right-Bank Forest-Steppe of Ukraine includes 10 species of phytophages of white cabbage, 2 species of pests of cucumbers and 7 species of entomophages.
