目的 掌握北京首都第二机场建设前该地区蚊种构成、密度及季节消长情况,为控制蚊媒传染病提供科学参考。方法 以机场建设规划图大兴区占地位置为基准,由东向西南方向选取6个自然村为监测点,采用二氧化碳诱蚊灯,于2014年6－10月每旬1次,于日落前1 h开启诱蚊灯,连续监测2 h,捕获蚊虫进行种类鉴定、计数。结果 此次调查共捕蚊5883只,隶属2亚科4属5种,淡色库蚊为优势种;大兴区首次捕到骚扰阿蚊;6月下旬为蚊虫密度高峰期;流行性乙型脑炎病毒核酸检测为阴性。结论 基本掌握了北京首都第二机场建设前(大兴区辖区)蚊种构成、密度、季节消长等情况。监测结果可以为今后评估蚊媒相关性传染病发生风险、开展蚊虫防治提供科学依据。

Objective Master the mosquito species composition, density and seasonal fluctuation before the second Beijing Capital Airport construction, to provide a scientific reference for the control of mosquito-borne infectious diseases. Methods Based on Daxing covers location of airport construction plan, selecting six natural villages for monitoring from east to south-west. Opening the lure mosquito lamp at one hour before sunset, continuous monitor mosquito for 2 hours using the lure mosquito lamp of carbon dioxide, once every ten-day in June to October 2014. Identifying species and counting the captured mosquitoes. Results In total 5883 mosquitoes were captured, belonging to two subfamilies, four genera, five species. Armigeres subalbatus was collected in Daxing area for the first time. Culex pipiens pallens was the perdominant species. The mosquitoes density peak was in late June. Testing negative results of Japanese encephalitis virus nucleic acid. Conclusion Mastering the mosquito species composition, density and seasonal fluctuation before the second Beijing Capital Airport construction. The monitoring results can provide a scientific basis for the assessment of risk correlation mosquito-borne infectious diseases, and for the prevention and control of mosquitoes.
