Resistance of Musca domestica to insecticides and control measures in Jiangsu province from 2004 to 2006

Objective To study resistance of Musca domestica to insecticides in Jiangsu province and provide basic information for using insecticides reasonably. Methods Topical application for housefly. Results Musca domestica had developed the highest resistance to DDVP in Rugao and Taizhou.It also had developed the highest resistance to deltamethrin in Yizheng,Rugao and Qidong.It had developed high resistance to DDVP in Yizheng,Yangzhong,Zhangjiagang and Qidong.And it had developed high resistance to permethrin in Rugao and Qidong.In Yizheng and Rugao it also had developed high resistance to cypermethrin.It had developed middle resistance to permethrin in Yizheng,Yangzhong and Zhangjiagang.And it had developed middle resistance to cypermethrin in Yangzhong,Zhangjiagang and Qidong.In Taizhou,it hadn't developed resistance to permethrin and cypermetrin. Conclusion It was essential to use insecticides reasonably based on the results of resistance investigation and call for integrated pest management.
