摘　　要：本文报道ＧＰ杀虫剂对蚜虫的４种优势种天敌不同发育阶段的室内毒效测定结果。ＧＰ杀虫剂对４种天敌的成虫和蛹只具弱毒效；对幼虫和卵的毒力则因天敌种类不同而不同，其中对大灰食蚜蝇的毒性相对较强。The results of laboratory determination on the toxicity of germ metabolite and plant extract compound bioinsecticide (G P) to different developmental stages of four dominant species of natural enemies of aphids were reported in this paper. G P insecticide was possessed of weak toxicity to adult and pupa of the four species of natural enemies tested. The toxicity of G P insecticide to larvae and eggs of different species of natural enemies was different and that to Syrphus corollae (Fabricius)was higher than to other species.
