摘　　要：分别采用浸叶法与喷雾法测定了7类10种杀虫剂对潜蝇姬小蜂幼虫、蛹和卵的毒性。结果表明:①爱福丁对幼虫的触杀毒性最高,24h后的死亡率达91 9%;天王星、7051杀虫素、康复多和巴丹次之,分别为45 2%、43 1%、41 2%、35 7%;灭蝇胺、卡死克、印楝、害极灭对幼虫的毒性较低,死亡率分别为14 6%、7 2%、5 7%、5 4%;②潜蝇姬小蜂的卵与蛹对所测杀虫剂相对不敏感,处理间差异不显著。The toxicity of insecticides to larvae,pupae and egg of Diglyphus isaea was assayed by residual film and sprayed.The results showed as follows:①Aifuding(abamectin)was the most highly toxic to the larvae of D.isaea in 24h and its mortality was (91.9?%.)Larvae mortality caused by Bifenthrin,imidacloprid and cartap were 45.2?%,41.2?% and 35.7?%,respectively.Cyromazine,flufenoxuron,azadirachtin and agrimec were slightly toxic to the larvae,with 14.6?%,7.2?%,5.7?% and 5.4?% larvae mortality,respectively;②All insecticides tested were no toxic to the egg and pupae.
