摘要: 目的 分析家蝇对杀虫剂的抗药性现状及发展趋势,为该地区害虫防制提供理论基础。方法 微量点滴法。结果罗庄、赵集、裴营、城关、桑庄、杨营和刘集7个采样点1997~2004年家蝇对溴氰菊酯的平均半数致死剂量(LD50)依次为0.007、0.013、0.015、0.018、0.022、0.016、0.014、0.013μg/♀,抗性指数依次为14.0、26.0、30.0、36.0、44.0、32.0、28.0、26.0;对敌敌畏的平均LD50依次为0.148、0.247、0.359、0.427、0.573、0.548、0.519、0.531μg/♀,抗性指数为14.8、24.7、35.9、42.7、57.3、54.8、51.9、53.1。结论 1997~2001年豫西南地区家蝇的抗药性呈上升状态,2001年以后呈现下降趋势。

Abstract: Objective To provide evidence for housefly,Musca domestica,prevention and control by analyzing housefly insecticide resistance. Methods The insecticide resistance of housefly were determined by topical application method. Results The LD50valuesof housefly to deltamethrin and DDVP were 0.007,0.013,0.015,0.018,0.022,0.016,0.014,0.013 μg/♀and 0.148,0.247,0.359,0.427,0.573,0.548,0.519,0.513 μg/♀ and the average resistant ratios were 14.0,26.0,30.0,36.0,44.0,32.0,28.0,26.0and 14.8,24.7,35.9,42.7,57.3,54.8,51.9,53.1respectively in seven sample sites from 1997 to 2004. Conclusion The resistant levels of housefly to 2 kinds of insecticide were going up from 1997 to 2001 and going slow down after 2001.
