几种杀虫剂对甘蔗绵蚜的室内毒力测定

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 >imidacloprid TC >D+B>chlorpyrifos TC>D+S.The results provided bases for selecting suitable insecticides to control the Ceratovacuna lanigera(Zehntner).
