摘　　要：目的了解徐州市家蝇对溴氰菊酯等常用杀虫剂的抗性现状,为合理选用化学杀虫剂,指导家蝇防制提供科学依据。方法选用点滴法测定家蝇半数致死剂量(LD50)。结果徐州市家蝇对高效氯氰菊酯、溴氰菊酯、敌敌畏的LD50分别为0.064、0.010和0.037μg/♀;家蝇对高效氯氰菊酯的抗性系数为9.14倍,属低抗;对溴氰菊酯和敌敌畏的抗性系数分别为50.00和61.67倍,均为高抗。结论为有效控制家蝇的危害,应注重对其综合治理,控制其孳生地,提倡物理防制;对家蝇的化学防治,应定期开展家蝇对常用杀虫剂的抗药性监测工作,合理使用杀虫剂。Objective To determine the resistance of Musca domestica to commonly used insecticides to inform proper application of chemical killing agents.Methods The median lethal dose（LD50） for M.domestica was determined by the dripping method.Results The LD50 values of beta-cypermethrin,deltamethrin,and dichlorvos for M.domestica were 0.064,0.010,and 0.037 μg/♀,respectively,and the corresponding resistance coefficients of M.domestica were 9.14,50.00 and 61.67,respectively.M.domestica showed low resistance to beta-cypermethrin and high resistance to deltamethrin and dichlorvos.Conclusion For effective control of M.domestica,comprehensive control strategies shall be employed,such as eliminating breeding places and physical management,chemical control and regular resistance monitoring,along with appropriate application of pesticides.
