Fokin A. The ecological substantiation of optimization integrated plant protection vegetable crops of the pests in the Forest-Steppe and Steppe zone of Ukraine

The dissertation work is devoted ethological of plant protection models with 10-90% levels of biological control are analyzed. Technology of breeding and usage of predatory entomophagous wasps-polistes was created on the base of studying ecology and biology of these insects. It was studied ecology of parasitic specie Latibulus argiolus Rossi. The representative the helpfulness optimal levels yield losses for harm-ful of soil pests (for example mole cricket, whites May melolontha, west root-worm beetle). The risk assessment for the dangerous quarantine pests Spodoptera eridania Cramer, S. frugiperda (J.E. Smith), S. littoralis Boisd and Naupactus leucoloma Boh. has been given on the basis of modeling results on the territories on Europe and Ukraine.
