在实验室条件下通过药膜法和卵卡浸渍法测定了10种蔬菜田防治小菜蛾Plutella xylostella（L.）的常用杀虫剂对拟澳洲赤眼蜂Trichogramma confusum Viggiani的影响,旨在评估各药剂对该蜂不同发育阶段的安全性,为小菜蛾防治过程中杀虫剂的合理施用提供科学依据。结果表明,高效氯氰菊酯、多杀菌素、阿维菌素、溴虫腈和杀螟丹对拟澳洲赤眼蜂成蜂有明显的触杀毒性。杀螟丹处理显著降低羽化率（0～34.37%）,在卵期和预蛹期处理还导致拟澳洲赤眼蜂畸形;多杀菌素在成虫期前的各处理均显著影响拟澳洲赤眼蜂的发育;溴虫腈在卵期、幼虫期和蛹期处理对拟澳洲赤眼蜂的发育存在不同程度的影响;而氟啶脲、茚虫威、苏云金芽孢杆菌、虫酰肼和丁醚脲对拟澳洲赤眼蜂成蜂及各发育虫态均较安全,为小菜蛾生防区理想的配合药剂。

Effect of ten insecticides on Trichogramma confusum Viggiani was determined and their safety to different developmental stages of the parasitoid was evaluated under laboratory condition by insecticide film method and dipping method. The results showed that betacypermethrin, spinosad, avermectins, chlorfenapyr and cartap had significant toxic effect on wasp adult survival. Cartap reduced emergence rate （0--34.37%） of T. confusum when the parasitoid was treated at each preimaginal developmental stage. And treatment with cartap at both egg and prepupa stages resulted in higher rate of deformity in the emerged adults than that in the control. Spinosad and chlorfenapyr significantly affected development of T. confusum when applied to preimaginal developmental stages. Chlorfluazuron, indoxacarb, Bacillus thuringiensis, tebufenozide and diafenthiuron were relatively safe to T. confusum, suggesting that these insecticides are compatible with the parasitoid.
