Zakharova T. Selectivity of insecticides action in system of phytophag - entomophag in agrobiocenosis.

Obiect - Rhopalosiphum padi L., Coccinella 7-punctata L., Mamestra brassicae L., Trichogramma evanescens Westw., Pieris brassicae L., Apanteles glomeratus L. Purpose - to investigate the peculiarity of modern insecticides selective action from three classes (phosphororganics, pyrethroids and carbomates) in the insects system " phytophag - entomophag" in agrobiocenosis. Field and laboratory methods have been used. The results have been processed on computers with the help of mathematical statistics methods. It was established the selective insecticides for entomophags (pyrimor, acetec, mavric 2F). The possibility of using acetec and pyrimor in the integrated protection of the pea culture against pea aphis was based. The highg efficacy of basudin and Bi-58 new on the cabbage culture against P.brassicae was established. Use - crop protection
