摘要: 目的 掌握上海市奉贤区白纹伊蚊对常用杀虫剂的抗性水平及发展趋势,为城市重大活动病媒生物保障及登革热防控提供科学依据。方法 采用世界卫生组织推荐的幼虫浸渍法检测白纹伊蚊幼蚊的抗药性。结果 2015、2018和2019年,白纹伊蚊幼蚊对双硫磷、溴氰菊酯、高效氯氰菊酯3种杀虫剂均呈现出不同程度的抗药性,抗性系数整体呈现先上升后下降的趋势。近5年来,对双硫磷的抗药性均低于溴氰菊酯和高效氯氰菊酯2种药物,2015、2018年维持在低抗水平,2019年下降至敏感水平(1.25倍);对溴氰菊酯的抗药性,2018年抗性倍数最高,达到高抗水平(68.75倍),呈现出由中抗-高抗-中抗的波动趋势;对高效氯氰菊酯的抗药性2015、2018年维持在中抗水平,2019年下降至低抗水平(7.00倍)。2019年奉贤区控制幼蚊的杀虫剂主要为有机磷类,其中双硫磷用量占总用药量的33.87%;控制成蚊的杀虫剂主要为拟除虫菊酯类和氨基甲酸酯类,其中高效氟氯氰菊酯、氯菊酯·烯丙菊酯、氯菊酯·四氟醚菊酯用量占41.17%。结论 奉贤区白纹伊蚊对溴氰菊酯和高效氯氰菊酯类杀虫剂已产生抗药性,应采用合理轮用或混用杀虫剂的方式,以有效缓解和降低抗药性的产生。

Abstract: Objective To grasp the resistance levels of Aedes albopictus to commonly used insecticides and their trends in Fengxian district, Shanghai, China, and to provide a scientific basis for the protection against vectors and the prevention and control of dengue fever in the major urban activities. Methods The larval dipping method recommended by the World Health Organization was used to determine the insecticide resistance of Ae. albopictus larvae. Results In 2015, 2018, and 2019, the Ae. albopictus larvae showed varying degrees of resistance to three insecticides, temephos, deltamethrin, and beta-cypermethrin, and the resistance coefficient overall showed an upward trend first and then a downward trend. In recent 5 years, the overall level of resistance to temephos has been lower than that to deltamethrin and beta-cypermethrin, which remained at a low level from 2015 and 2018 and decreased to a sensitive level (resistance ratio 1.25) in 2019; the resistance to deltamethrin was highest in 2018, reaching a high resistance level (resistance ratio 68.75), and showing a fluctuating trend from medium to high and then to medium resistance; the resistance to beta-cypermethrin remained at a medium level from 2015 and 2018, and dropped to a low level (resistance ratio 7.00) in 2019. In 2019, the insecticides that controlled mosquito larvae were mainly organophosphates, of which the dose of temephos accounted for 33.87% of the total dose of insecticides used; the insecticides that controlled adult mosquitoes were mainly pyrethroids and carbamates, of which the doses of beta-cyfluthrin, permethrin-allethrin, and permethrin-tetramethylfluthrin accounted for 41.17%. Conclusion Aedes albopictus in Fengxian district has developed resistance to deltamethrin and beta-cypermethrin insecticides. A reasonable rotation or mixed use of insecticides should be adopted to effectively alleviate and reduce the development of insecticide resistance.
