摘要:

目的 了解呼和浩特市及周边旗(县)淡色库蚊对常用卫生杀虫剂的抗性水平,为制定科学、合理、有效的防治措施提供依据。方法 采用世界卫生组织推荐的幼虫浸渍法,测定幼虫对常用卫生杀虫剂的敏感性,获得半数致死浓度及其95%可信区间,比较其抗药性程度。结果 呼和浩特市市区、清水河县、武川县、托克托县、和林格尔县、土默特左旗淡色库蚊对溴氰菊酯的抗性倍数分别为1.09、0.05、0.77、0.09、0.87和0.09倍;对氯菊酯的抗性倍数分别0.97、0.09、0.63、0.11、1.16和0.07倍;对高效氯氰菊酯的抗性倍数分别为1.18、0.08、0.19、0.01、0.08和0.06倍;对双硫磷的抗性倍数分别为1.22、0.73、7.96、0.68、1.21和1.37倍;对敌敌畏的抗性倍数分别为5.02、0.89、0.01、0.09、1.06和0.17倍。结论 除武川县淡色库蚊对双硫磷、呼和浩特市市区淡色库蚊对敌敌畏产生低抗外,其他地区淡色库蚊对5种杀虫剂均处于敏感状态。

Abstract:

Objective To monitor the resistance status of Culex pipiens pallens to commonly used insecticides in Hohhot city and the surrounding areas for management of insecticide resistance development. Methods The susceptibility of larvae to five commonly used insecticides was tested by WHO larval immersion method to determine the median lethal concentration (LC50) and 95% confidence intervals (95%CI). Results In Hohhot city, Qingshuihe, Wuchuan, Tuoketuo, Helingeer county, and Tumed Left Banner, the resistance ratios of Cx. pipiens pallens for deltamethrin were 1.09, 0.05, 0.77, 0.09, 0.87, and 0.09 fold; for permethrin were 0.97, 0.09, 0.63, 0.11, 1.16, and 0.07 fold; for beta cypermethrin were 1.18, 0.08, 0.19, 0.01, 0.08, and 0.06 fold; for parathion were 1.22, 0.73, 7.96, 0.68, 1.21, and 1.37 fold; for DDVP were 5.02, 0.89, 0.01, 0.09, 1.06, and 0.17 fold, respectively. Conclusion Culex pipiens pallens in Hohhot city and the surrounding areas is overall susceptible to above five commonly used insecticides, except that Cx. pipiens pallens in Wuchuan country and Hohhot city have low resistance to parathion and DDVP, respectively.
