Abstract: Objective To investigate the species, density, and seasonality of mosquito vectors in the construction area of Beijing Daxing International Airport, China and establish basic records for mosquito vectors, and to provide a reliable basis for early warning of the risk of mosquito-borne diseases in the construction and future operation of the airport. Methods On the basis of the accomplished project of the Science and Technology Committee of Daxing District in 2014-"An investigation into the baseline status of vectors in the construction area of Daxing new airport", we selected mosquitoes as the major surveillance target in 2015 as they are closely related to vector-borne diseases, and carried out surveillance in the area of the new airport restricted in Beijing till the end of October 2017. Surveillance surrounded the terminal of the new airport and covered an area between 116°21'49″ and 116°26'50″ eastern longitudes and between 39°29'26″ and 39°33'25″ northern latitudes, consisting of Lixian town and Yufa town in Daxing district, Beijing. Surveillance was done once per 10 days from the beginning of May to the end of October in each year, continuing for 4 years. Six villages were randomly selected within the surveillance area, and they were adjusted every year because of demolition and relocation, but the total number remained unchanged. Three surveillance points (the environment outside farmhouses) were set up in each village. Adult mosquitoes were collected by the carbon dioxide lamp trapping method, and were identified and counted in the laboratory. Results Surveillance of adult mosquitoes continued for 4 years from 2014 to 2017, collecting 26 687 mosquitoes from 17 villages of 2 towns, with a density of 11.01 mosquitoes/lamp·hour. Those adult mosquitoes involved 4 genera and 6 species; Cx. pipiens pallens was the dominant species, accounting for 85.63%; minor species were Armigeres subalbatus and Aedes albopictus; Cx. tritaeniorhynchus and Anopheles sinensis were observed in relatively small numbers. The peak period of mosquito density was between late June and early September, with Ae. albopictus later in August. Conclusion The baseline data of the mosquito species, density and distribution were collected from the surrounding area of the terminal of Beijing Daxing International Airport. The data will provide the scientific basis for risk assessment, control planning and and efficacy evaluation for mosquito and mosquito borne diseases in this area.

摘要: 目的 了解北京大兴国际机场建设地区蚊媒种类、密度和季节消长情况,建立蚊媒基础档案,同时为机场建设及未来运行中预警蚊媒传染病发生风险提供可靠依据。方法 在2014年完成大兴区科学技术委员会项目《大兴区新机场建设地区病媒生物现状调查研究》的基础上,2015年选取与媒介传染病关系密切的蚊媒作为主要监测指标,继续在大兴国际机场北京区域开展监测,至2017年10底结束。监测范围以该机场航站楼为核心,在其116°21'49″~116°26'50″E,39°29'26″~39°33'25″N内开展监测,包括北京市大兴区礼贤和榆垡镇,连续监测4年,每年5月上旬开始至10月底结束,每旬监测1次。每年在监测范围内随机选取6个自然村,受拆迁影响,6个自然村每年都有调整,但总数不变。每村设3个监测点(农户外环境),采用CO2诱蚊灯法诱捕成蚊,成蚊鉴别计数在实验室完成。结果 2014-2017年连续4年成蚊监测,共涉及2镇17个村,捕蚊4属6种26 687只,蚊密度为11.01只/(灯·h),淡色库蚊为优势种,构成比为85.63%;其次是骚扰阿蚊和白纹伊蚊,三带喙库蚊和中华按蚊均监测到,但数量较少;蚊密度高峰集中在6月下旬至9月上旬,白纹伊蚊高峰在8月。结论 获得了北京大兴国际机场航站楼周边蚊种、数量和密度等基线数据,为新机场国际口岸输入蚊虫及蚊媒传染病风险评估、未来蚊媒监测与控制项目规划和效果评价提供了科学基础。
