The biological and environmental features of reproduction and distribution of dominant harmful organisms in modern conditions

The article presents research on the features of reproduction dominant pests species organisms in agrobiocenoses growing cereals, leguminous crops, sunflowers and flowers. describes latest ways to control a complex soil harmful insect short-rotation field crop, as well aerogenic integrated use plant protection products nutrition systems. In addition, we have identified individual levels biologically oriented mechanisms self-regulation with measures stabilize functioning agrocenoses, which are supplied natural adaptive reactions trophic chains.
 region observations, is controlled by spiders, nematodes, mites, pathogens, predators parasites. A variety causative agents bacterial, fungal, viral protozoal diseases phytophagous insects deserve special attention.
 Parasites appear everywhere chains 16 rows class. recent years, predatory ground beetles from number Hymenoptera that feed aphids corn crops unreasonable intensive nitrogen fertilizers acquired significant importance.

Measures been developed realize productivity potential flowers through low-cost determine controlling phytophages development types according characteristics their biology ecology
