GABA靶标杂环杀虫剂FIPRONIL对卫生害虫的活性研究

Research on the Activity of Heteronuclear Insecticide FIPRONIL with GABA Target against Pests of Health Importance

目的 :研究作用机制独特的新型杂环杀虫剂FIPRONIL对蚊、蝇、蠊 3种卫生害虫的活性 ,评价其在卫生害虫防制领域中应用的实际意义。方法 :微量点滴法、浸液法、药膜法、密闭圆筒喷雾法。结果 :FIPRONIL对淡色库蚊、家蝇及德国小蠊的致死性均优于拟除虫菊酯中的两种代表性杀虫剂氯菊酯和胺菊脂 ,击倒性则反之。对淡色库蚊幼虫的LC50 为 0 .0 1162 ppm ,对家蝇、德国小蠊的LD50 分别为 0 .0 0 371、0 .0 0 377μg/虫。结论 :FIPRONIL具备对 3种卫生害虫的高效毒力及无交互抗性的独特作用机制 。

This paper reports the activities of new heteronuclear insecticide FIPRONIL with the special mechanism on three kinds of health pests. The results show that FIPRONIL was superior to two kinds of typical pyrethroid insecticide-permethrin and tetramethrin on the killing activity, the knock-down activity was the converse. The LC 50 of larvae of Culex pipiens pallens was 0.011 62 ppm, the LD 50 of Musca domestica and Balattella germanica was 0.003 71 μg/body and 0.003 77 μg/body respectivity. For the reason of high toxic activity on three kinds of health pests and the special action mechanism without resistance each other, it seems need to enlarge its use on the fields of public health.
