摘　　要：在田间自然情况下,评价了7类9种杀虫剂(分属氨基甲酸酯类、氯烟酰类、昆虫生长调节剂、沙蚕毒素、阿维菌素、植物源农药与有机磷)对潜蝇姬小蜂田间种群数量和寄生率的影响。结果表明:连续两次施用爱福丁、甲胺磷、天王星、康复多与巴丹后,潜蝇姬小蜂的种群数量和寄生率均有明显的下降,且处于相对较低的水平。而灭蝇胺与印楝在施用后,对田间种群数量影响较小,寄生率(%)比对照和其它处理有大幅度的上升。Effects of 9 insecticides on the field population fluctuation and parasitism of Diglyphus isaea were evaluated. The results indicated that the dynamics of D. isaea population and parasitism were decreased obviously and were at a comparative lower level after two continuous applications of aifuding, methamidophos, bifenthrin, imidacloprid and cartap. The application of cyromazine and azadirachtion had fewer effects on the field population fluctration, but the parasitism was increased greatly as compared with the control and other treatments.
