摘要:

目的 了解2011-2014年北京首都国际机场周边蚊虫种类及密度和病原携带情况, 为北京市蚊媒传播疾病防控策略的制定提供科学依据。方法 2011-2014年每年的5-10月在机场周边2000 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对首都机场周边2011-2014年蚊虫种类及密度和病原携带情况监测数据进行流行病学分析。结果 2011-2014年共捕获成蚊126 212只, 其中淡色库蚊占捕获总数的85.59%, 为优势蚊种, 三带喙库蚊、中华按蚊、白纹伊蚊分别占13.95%、0.28%和0.18%;2011-2014年蚊虫年平均密度指数分别为40.74、45.18、28.76和37.80只/(灯·h), 总体蚊虫月密度在0.29~113.38只/(灯·h)之间, 密度高峰在6-9月;月平均密度高峰淡色库蚊在6月, 三带喙库蚊在9月, 中华按蚊和白纹伊蚊均在8月;7种生境蚊虫总体年平均密度在4.93~146.17只/(灯·h)之间, 其中温榆河水系三带喙库蚊、淡色库蚊和中华按蚊密度最高, 白纹伊蚊在机场中部密度最高;未发现携带有疟疾、登革热和流行性乙型脑炎病毒的蚊虫。结论 首都机场周边蚊虫密度较高, 河边等野外环境是其栖息的主要场所, 密度高峰期在6-9月, 淡色库蚊、三带喙库蚊是主要蚊种, 发生本地感染疟疾、登革热病例的风险极低。

Abstract:

Objective To investigate the species, densities and carried pathogens of mosquitoes in surrounding areas of Beijing Capital International Airport during 2011 to 2014, and to provide a scientific basis for the control and prevention of mosquito-borne diseases. Methods Seven monitoring stations within 2000 meters around Beijing Capital International Airport were included in this study. Carbon dioxide light traps were used to capture mosquitoes according to GB/T 23797-2009. Descriptive epidemiological analysis was performed with mosquito monitoring data of density and carried pathogen 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%). The annual average density indices of mosquitoes in the 4 years were 40.74, 45.18, 28.76 and 37.80 mosquitoes per light-hour, respectively. The monthly average densities were ranged from 0.29 to 113.38 mosquitoes per light-hour. The peak of adult mosquito density appeared from June to September, and that about Cx. pipiens pallens and Cx. tritaeniorhynchus were June and September, that about Ae. albopictus and An. sinensis were all August. The annual average density indices of mosquitoes were ranged from 4.93 to 146.17 mosquitoes per light-hour in seven monitoring stations. The density for Cx. pipiens pallens, Cx. tritaeniorhynchus and An. sinensis were the highest at the riverside, for Ae. albopictus that was the highest in central Airport. There were no mosquitoes that carried pathogens of malaria, dengue fever, Japanese encephalitis. Conclusion The density indices of mosquitoes were high in surrounding areas of Beijing Capital International Airport. Mosquitoes mainly inhabited outdoor environments such as riverside. The activity peak period of mosquitoes was between June to September. Cx. pipiens pallens and Cx. tritaeniorhynchus were the predominant species. The risks on spread indigenous malaria and dengue fever were low.
