摘　　要：采用药膜法测定了7类10种杀虫剂对潜蝇姬小蜂成虫的毒性。结果表明:①巴丹、甲胺磷、爱福丁、7051杀虫素、天王星对成虫的毒性较高,24h的死亡率均达100%,并且反应较快,击倒力强;害极灭、康复多次之;而灭蝇胺、印楝、卡死克对成虫较为安全;②阿维菌素类杀虫剂对潜蝇姬小蜂成虫的毒性存在较大的差异。其中,爱福丁毒性最高,7051杀虫素次之,害极灭相对较低;③植物源杀虫剂和昆虫生长调节剂对潜蝇姬小蜂成虫较为安全,可协调应用于斑潜蝇的综合治理中,如印楝、灭蝇胺。The toxicity of insecticides to adults of Diglyphus isaea was assayed by residual film in laboratory. The results showed as follows:(1)Cartap,ethamidophos,aifuding,7051 insecticide and bifenthrin were high touch toxicity to the adults,the mortality were 100?%in 24h,and Azadirachtin,flufenoxuron and cyromazine were relatively safe to the adults.(2)The different products of Avermectin had different toxicity to D.isaea.For example,of Avermectin insecticides,aifuding was highly toxic and agrimec was slightly toxic.(3)Bioinsecticides can coordinate with D.isaea in IPM of leafminer,such as cyromazine and azadirachtin.
