摘　　要：测定了11种杀虫剂对江苏省南京市马群和山东泰安市郊区斜纹夜蛾田间种群的毒力。用点滴法测定结果表明:6种杀虫剂对南京斜纹夜蛾3龄幼虫的毒力(LD50)大小顺序为:高效氯氰菊酯>氯氟氰菊酯>辛硫磷>马拉硫磷>毒死蜱>灭多威;对泰安斜纹夜蛾幼虫的毒力大小顺序为:高效氯氰菊酯>氯氟氰菊酯>马拉硫磷>辛硫磷>毒死蜱>灭多威。高效氯氰菊酯对两种群的毒力最大,灭多威的毒力最小。山东泰安种群较南京种群对杀虫剂略敏感。用浸叶法测定结果表明:9种杀虫剂对南京斜纹夜蛾3龄幼虫的毒力(LC50)大小顺序为:除尽>菜喜>高效氯氰菊酯>米螨>抑太保>氯氟氰菊酯>辛硫磷>毒死蜱>抑食肼。对山东泰安斜纹夜蛾3龄幼虫的毒力大小顺序为:除尽>菜喜>抑太保>高效氯氰菊酯>毒死蜱>辛硫磷>米螨>氯氟氰菊酯>抑食肼。除尽和菜喜对两种群的毒力最高,抑食肼的毒力最低。山东泰安斜纹夜蛾种群除对氯氟氰菊酯和米螨的敏感性略低于南京种群外,对其他药剂均比南京种群敏感。Toxicity of 11 insecticides to the common cutworm,Spodoptera litura was evaluated in laboratory. The orders of toxicity to Spodoptera litura collected from Nanjing City,Jiangsu Province were beta-cypermethrin>lambda-cyhalothrin>phoxin>malathion>chlorpyrifos>methomyl with topical application and chlorfenapyr>spinosad>beta-cypermethrin>tebufenozide>chlorfluazron>lambda-cyhalothrin>phoxin>chlorpyrifos>RH-5849 with leaf-dipping method,respectively. The orders to Spodoptera litura collected from Taian City,Shanding Province were beta-cypermethrin>lambda-cyhalothrin>malathion>phoxin>chlorphyrifos>methomyl and chlorfenapyr>spinosad>chlorfluazron>beta-cypethrin>chlorpyrifos>phoxin>tebufenozide>lambda-cyhalothrin>RH-5849,respectively.
