Objective: To analyze the resistance of house flies to insecticides in Hubei Province from 1991 to 1998 and to discuss the control strategies. Method: micro-drip method. Results: The resistance of housefly to deltamethrin, permethrin, tetramethrin and dichlorvos was high in Hubei Province, increasing by 4.32, 1.78, 1.27 and 60.34 times respectively over that in 1990. Conclusion: Musca domestica has different levels of resistance to four kinds of insecticides. Monitoring and technical guidance should be strengthened to implement comprehensive treatment and rational use of drugs to delay the development of housefly resistance.
