目的了解济南市家蝇26年来抗药性的发展动态,探讨其防制对策。方法采用微量点滴法,对不同年份采集的不同地区家蝇进行生物测定,以确定家蝇的抗药性状况及其发展趋势。结果 1982年济南市区及周边地区家蝇对常用菊酯类药剂均处于敏感阶段,26年后对菊酯类药剂敏感性均有不同程度的下降。2008年,济南市家蝇对溴氰菊酯的抗性为75.00～211.67倍,对高效氯氰菊酯的抗性为25.52～116.21倍,均已达到中、高度抗性。结论济南市区及周边地区的家蝇对菊酯类药剂已产生不同程度的抗性,各县(市、区)应根据当地的具体情况制定防制对策。
Objective To understand the development of Musca domestica in Jinan over the past 26 years and to explore its control strategy. Methods The micro-drip method was used to conduct bioassay of housefly collected from different areas in different years to determine the resistance of housefly and its development trend. Results In 1982, housefly in Jinan urban area and surrounding areas were all sensitive to pyrethroid agents. After 26 years, the sensitivity to pyrethroid agents decreased to some extent. In 2008, the resistance of house fly to deltamethrin in Jinan was 75.00-211.67 times, and the resistance to beta-cypermethrin was 25.52-116.21 times, both of which reached medium and high resistance. Conclusion Musca domestica in Jinan urban area and its surrounding areas have different degrees of resistance to pyrethroid agents. All counties (cities, districts) should formulate their control measures according to local conditions.
