title: [Anticholinesterase effect of organophosphorus and pyrethroid insecticides on some phytophages, their predators, and parasites].
abstract: The normal catalytic activity of insects cholinesterases was determined: Apanteles glomeratus L., Coccinella septempunctata L., Rhopalosiphum padi L. and Pieris brassicae L. Constants of bimolecular interaction of three insecticides for insects were calculated: cholinesterase of C. septempunctata were the most sensitive to Bi-58 new [Kii = (4.54 +/- 0.23). 10(4)], cholinesterase of aphids was revealed to be the most sensitive to acetec [Kii = (2.9 +/- 0.14). 10(5)]. The studies have been carried aimed to determination of anticholinesterase actioncoefficients: acetec demonstrated the selective anticholinesterase activity in the system Aphididae--Coccinellidae (Kache = 118.9). Its anticholinesterase activity underlies in the toxicity mechanism for the given species.
