摘　　要：目的 :研究屠宰场家蝇的抗药性情况。方法 :微量点滴法测出卫生杀虫剂对家蝇的致死中量。结果 :家蝇对 10种卫生杀虫剂敏感程度不同 ,其中对氯菊酯最敏感 ,对益必添和甲醚菊酯产生了耐药性 ,对其他杀虫剂产生了抗药性 ,对溴氰菊酯和敌敌畏抗性最高 ;溴氰菊酯的抗性发展速度最快 ,氯菊酯的抗性发展速度较慢。结论 :从抗药性角度考虑 ,氯菊酯可以优先用于屠宰场家蝇防制。Objective:To study the resistance against ten insecticides of houseflies in slaughterhouse in Hefei city. An hui province.Methods:House flies in slaughterhouse were tested for resistance to ten insecticides (Permethrin, Alphamethrin,Esbiothrin,Tetramethrin,Methothrin,Deltamethrin,dichlorovos, Trichlophon, Acephate,Bassa) by median lethal dose (LD 50 ). Result:The flies were highly resistant to Deltamethrin and Dichlorovos (more than 100 times), and susceptible or tolerant to Permethrin,Esbiothrin and Methothrin. Conclusion:In slaughterhouse house flies control by chemical method should be selected the suitable insecticide just as Permethrin.
