摘要: 目的 了解合肥市人居及周边环境中家蝇的抗药性水平现状,为制定科学、规范的卫生杀虫剂使用、管理策略及科学开展蝇类防制工作提供科学依据。方法 成蝇抗药性测定采用点滴法。采用SPSS 22.0统计软件的Probit模块对数据进行处理,求毒力回归方程及半数致死剂量(LD50)和95%置信区间。结果 2021年合肥市家蝇对敌敌畏、氯菊酯、溴氰菊酯、顺式氯氰菊酯、高效氯氰菊酯和高效氯氟氰菊酯6种杀虫剂的LD50值分别为0.321 55、0.775 62、0.956 54、0.519 00、0.542 90和0.532 90 μg/雌,抗性倍数依次为28.21、133.73、1 471.60、112.83、63.13和166.53倍,对敌敌畏和5种菊酯类均属于高度抗性水平。结论 合肥市家蝇对6种常用卫生杀虫剂均已产生高度抗药性,应停止或减少这6种杀虫剂的使用,寻找和轮换使用其他作用机制或敏感型的卫生杀虫剂,以期延缓抗药性的发生和发展速度。

Abstract: Objective To investigate the insecticide resistance level of Musca domestica in human settlements and surroundings in Hefei, China, and to provide a scientific basis for insecticide use and management as well as fly control. Methods The topical application method was used to determine the resistance levels of M. domestica to insecticides. Probit analysis was performed with SPSS 22.0 software to calculate the toxicity regression equation as well as median lethal dose (LD50) and 95% confidence interval. Results For M. domestica in Hefei, 2021, the LD50 values of dichlorvos, permethrin, deltamethrin, alpha-cypermethrin, beta-cypermethrin, and lambda-cyhalothrin were 0.321 55, 0.775 62, 0.956 54, 0.519 00, 0.542 90, and 0.532 90 μg/♀, respectively; the relative resistance coefficients were 28.21, 133.73, 1 471.60, 112.83, 63.13, and 166.53, respectively, indicating high resistance levels of M. domestica to all the six insecticides. Conclusion M. domestica in Hefei developed high resistance to the six commonly used insecticides, which should be avoided or reduced in use. Other insecticides of high sensitivity or with different mechanisms of action should be used in alternation to delay the development of resistance.
