摘　　要：在室内用药液浸渍法进行了96%毒死蜱TC、98%吡虫啉TC、98%噻虫嗪TC及毒死蜱与其他两种药剂的混配制剂(D+B、D+S)对甘蔗绵蚜的毒力测定。结果表明:所选药剂对甘蔗绵蚜均具有较高的毒力,其毒力由高到底的排序为噻虫嗪>吡虫啉>D+B>毒死蜱>D+S。测定结果可为合理选择防治甘蔗绵蚜的农药提供理论依据。The toxicity of 96% chlorpyrifos TC , 98% imidacloprid TC , 98% thiamethoxam TC and mixed pesticides of chlorpyrifos with other two agents （D＋B, D＋S） to Ceratovacuna lanigera（Zehntner） were determined under laboratory conditions by leaf dipping method .The results showed that all of the pesticides had high toxicity with the order of thiamethoxam TC ＆gt;imidacloprid TC 〉D＋B〉chlorpyrifos TC〉D＋S.The results provided bases for selecting suitable insecticides to control the Ceratovacuna lanigera（Zehntner）.
