摘要
目的了解2011-2014年北京首都国际机场周边淡色库蚊分布及季节变化情况,为蚊媒性疾病的防控提供基础资料。方法于2011-2014年的5-10月在首都机场周边2 000 m范围内选取7个监测点,采用国家标准GB/T 23797-2009中的二氧化碳诱蚊灯法,通过描述性研究方法分析淡色库蚊密度分布情况。结果 2011-2014年共捕获成蚊126 212只,淡色库蚊为优势蚊种,占捕获总数的85.59%,三带喙库蚊、中华按蚊和白纹伊蚊分别占13.95%、0.28%和0.18%,捕获骚扰阿蚊1只;2011-2014年年度淡色库蚊平均密度分别为35.87、43.44、15.67和36.88只/（灯·h）,2012、2014年密度与2013年比较差异均有统计学意义（q=4.150、3.553,P＆lt;0.05）;总体蚊虫月密度为0.29~113.34只/（灯·h）,密度高峰在6-8月;7种生境蚊虫总体年平均密度为4.34~144.21只/（灯·h）,密度居前3位的生境分别为河边、机场中和机场北,河边与其他6种生境蚊虫年平均密度差异均有统计学意义（q=10.879、12.198、10.931、10.413、9.154、12.101,P＆lt;0.01）。结论首都机场周边淡色库蚊密度较高,河边等野外环境为其栖息的主要场所,应加强机场周边淡色库蚊监测。
Objective To investigate the densities and seasonality of Culex pipiens pallens in the vicinity of Beijing Capital International Airport during 2011 to 2014, and to provide a basic data for the control and prevention of mosquitoborne diseases. Methods Seven monitoring stations within 2 000 m around Beijing Capital International Airport were included in this study during 2011 to 2014. Carbon dioxide light traps were used to capture mosquitoes according to GB/T 23797-2009. Descriptive analysis was performed with mosquito monitoring data from 2011 to 2014 in surrounding areas of Beijing Capital International Airport. Results A total of 126 212 adult mosquitoes were captured within the 4 years of investigation. Culex pipiens pallens was the predominant mosquito species （accounting for 85.59% of all captured mosquitoes）, followed by Cx. tritaeniorhynchus （13.95%）, Anopheles sinensis （0.28%）, Aedes albopictus （0.18%）, and 1 Armigeres subalbatus. The annual average density indices of Cx. pipiens pallens in the 4 years were 35.87, 43.44, 15.67 and 36.88 mosquitoes per light-hour, respectively. There were significant differences on annual average density between 2012 and 2013 （q=4.150, P〈0.01）, between 2014 and 2013 （q=3.553, P〈0.05）, respeetively. The monthly average densities ranged from 0.29 to 113.34 mosquitoes per light-hour. The peak of adult Cx. pipiens pallens density appeared from June to August. The annual average density indiees of mosquitoes ranged from 4.34 to 144.21 mosquitoes per light-hour in seven monitoring stations. The densities for Cx. pipiens pallens were the highest at the riverside, the second were in central Airport, and the third were in parts of northern Airport. There were significant differences on annual average density between the riverside and the other 6 monitoring stations （P〈0.01）. Conclusion The density indices of Cx. pipiens pallens were high in surrounding areas of Beijing Capital International Airport. Culex pipiens pallens mainly inhabited outdoor e
