北京市顺义区白纹伊蚊密度及抗药性监测分析

Analysis on the density and insecticide resistance of Aedes albopictus in Shunyi District of Beijing

目的了解顺义区白纹伊蚊密度及抗药性水平。方法采用CO_(2)诱蚊灯法和诱卵器法开展密度监测,采用诊断剂量法进行抗药性监测。结果共布放CO_(2)诱蚊灯504台次,共捕获白纹伊蚊1 285只,白纹伊蚊密度为1.27只/(灯·h),全年密度峰值出现在8月,为3.22只/灯·h。共布放有效诱蚊诱卵器599个,诱蚊诱卵器指数为2.34%,峰值出现在8月,为8.08%。白纹伊蚊对高效氯氰菊酯和残杀威产生了抗性。结论顺义区白纹伊蚊防治应基于蚊虫监测结果,采用以环境治理为基础的综合防制措施。

Objective To understand the density and insecticide resistance of Aedes albopictus in Shunyi District.Methods The carbon dioxide mosquito trap lamp method and ovitrap method were adopted for the density surveillance, and the diagnostic dose method was used for the resistance determination.Results A total of 504 carbon dioxide traps were placed, and 1 285 Aedes albopictus were captured.The density of Aedes albopictus was 1.27 insects per lamp in an hour, and the peak density was 3.22 insects per lamp in an hour in August.A total of 599 effective ovitraps were distributed, 14 of which were positive, and the mosquito ovitrap index(MOI)was 2.34%.The peak appeared in August, with the MOI of 8.08%.The tested Aedes albopictus showed resistance to beta cypermethrin and propoxur.Conclusion The control of Ae.albopictus in Shunyi District should be based on the results of mosquito surveillance, and comprehensive control measures based on environmental management should be implemented.
