Abstract: Objective To investigate the density and species of the mosquitoes around Beijing Capital International Airport (BCIA) and the seasonal fluctuation of mosquito density, and to provide a scientific basis for controlling mosquitoes. Methods The CO2 light traps were applied to collect adult mosquitoes, which were subsequently identified and classified. Results A total of 22 715 mosquitoes (4 species, 3 genera) were trapped, including Culex pipiens pallens, Cx. tritaeniorhynchus, Anopheles sinensis, and Aedes albopictus, Cx. pipiens pallens were the dominant species (87.95%). The density index of mosquitoes was 44.54 mosquitoes per light trap in 1 hour. The peak density of mosquitoes occurred from August to September. Conclusion It provides a basis for controlling mosquitoes and mosquito-borne diseases by analyzing the density and species of the mosquitoes around BCIA and the seasonal fluctuation of mosquito density. The mosquito control should be strengthened around BCIA. Meanwhile, the density of mosquitoes should be subjected to systematic long-term monitoring and linked to mosquito-borne diseases by correlation analysis. Early warning system for vectors should be established to curb the incidence of mosquito-borne diseases.

摘要: 目的 掌握首都机场周边蚊虫密度、种类及其季节消长规律等本底情况, 为蚊虫防制提供科学依据。方法 采用CO2诱蚊灯法诱捕成蚊, 并对捕获蚊虫进行分类鉴定。结果 共捕获成蚊22 715只, 密度为44.54只/(灯·h), 密度高峰期为8-9月。所捕成蚊隶属3属4种, 分别为淡色库蚊、三带喙库蚊、中华按蚊和白纹伊蚊, 淡色库蚊为优势种, 占捕获总数的87.95%。结论 初步掌握首都机场周边蚊虫密度、种类、季节消长等情况, 为蚊虫防治以及蚊媒疾病的预防奠定了基础。建议加强首都机场周边蚊虫的防制工作, 同时, 对蚊虫密度进行长期系统的监测, 并结合蚊媒疾病进行相关分析, 建立病媒生物预警体系, 有效预防媒介疾病的发生和流行。
