摘　　要：本文报道Ｇ－Ｐ复合生物杀虫剂对大豆田蚜虫及其天敌毒效的室内测定和田间试验的结果。Ｇ－Ｐ４００倍液室内试验对大豆田蚜虫２４小时致死率为７７．３～８０．５％，４８小时达９１．３～９６．１％，田间试验防效达９１．０％，与氧化乐果１０００倍液的毒效相近。The results of laboratory test and field experiment on the toxicity of G P compound bioinsecticide to the aphid and its natural enemies in soybean field was reported in this paper. Spraying G P bioinsecticide dilution (400×) in laboratory, we got the aphid mortality of 77 3￣80 5% for 24 hours and 91 3￣96 1% for 48 hours. The field effect of G P dilution (400×) was 91 0% and G P bioinsecticide was with low toxicity to the natural enemies of aphid.
