目的掌握城市卫生害虫的抗性水平的动态变化状况,检验控制抗性发生与发展的措施的有效性。方法点滴法:于1995、1996、1997年前和2007、2009、2011年用常用化学杀虫剂对家蝇进行抗性试验。结果家蝇对有机磷类杀虫剂抗性在阶段性控制的15年后,重新变化为高度抗药性,而对拟除虫菊酯类抗性在10多年后在缓慢下降。结论在监测家蝇抗性动态变化的基础上,实施综合治理,注重环境整治,严格控制和合理调配化学用药,可延缓抗性的发展。
Objective To understand the dynamics of urban pest resistance levels and to test the effectiveness of measures to control the occurrence and development of resistance. Method of drip method: In 1995, 1996, before 1997 and 2007, 2009, 2011 with the commonly used chemical pesticides on housefly resistance test. As a result, the resistance of organophosphate insecticides to housefly changed again to highly resistant 15 years after the phased control, whereas the resistance to pyrethroid decreased slowly over 10 years later. Conclusion On the basis of monitoring the dynamic changes of housefly resistance, it is possible to delay the development of resistance by implementing comprehensive management, paying attention to environmental remediation, strictly controlling and rationally dispensing chemical drugs.
