摘要
室内条件下对七星瓢虫（Ｃｏｃｃｉｎｅｌｌａｓｅｐｔｅｍｐｕｎｃｔａｔａ）幼虫，成虫和蛹的触杀毒力测定结果表明，不同发育阶段的七星瓢虫对２０种杀虫剂的敏感度不同，以幼虫是敏感，成虫和蛹耐药性较强。所测２０种杀虫剂对七星瓢虫的毒性差异很大，结果为：高效氯氰菊酯，辛硫磷，甲基对硫磷，齐螨素和好年冬５种杀虫剂对七星瓢虫的成虫，幼虫和蛹均具有很大的毒性，在测试浓度下对成虫和幼虫的杀伤力均为１００％。
Toxicity of twenty insechcides to different developmental stages of Coccinella septempunc-tata was tested in laboratory. The susceptibilities of different stages of Coccinella septempumctata tothese insecticides is in the order of lareae, adult, and pupae. Toxicity of alphacypemethrin, phox-im, Parathion, abamectin and marshal to larvae, adults and pupae is high. Amitraz, triazamate,shachongshuang, chlorbenzuron, Bt, clofentezine yishijing piimicarb, imidacloprid and flufenox-uron are safe to Coccinella septempunctata.
