摘要
目的掌握首都空港口岸蚊类种群构成、分布、密度和季节消长,为防治口岸蚊类和蚊媒传染病提供科学依据。方法采用CO2诱蚊灯法对首都空港口岸不同生境蚊类进行调查,进行种类鉴定和病原体检测,并对资料进行统计分析。结果此次调查共捕获成蚊11457只,经鉴定隶属于1科3属5种;淡色库蚊占捕获总数的88.59%,为首都空港口岸优势蚊种,背点伊蚊为首都空港口岸罕见蚊种;平均密度39.78只/h·灯,最低密度0.73只/h·灯,最高密度71.9只/h·灯,呈现双峰波浪型变化;病原体检测均为阴性。结论首都空港口岸成蚊密度处于较高水平,季节消长规律明显,不同生境蚊种构成和平均密度存在一定差异,淡色库蚊为首都空港口岸的绝对优势种,应成为今后防治的重点;应在监测的基础上建立风险分析系统进行风险预警和风险管理。
Objective To understand the seasonal fluctuation, distribution, composition of the population and density of mosquitoes at Beijing Capital Airport, and to provide scientific basis for prevention and controlling of mosquitoes and mosquito-borne infectious diseases. Methods The mosquitoes were captured with CO2 lamp, the mosquitoes of diferent habitat distribution were identified and pathogens were detected. The data were analyzed by statistics. Results A total of 11 457 adult mosquitoes were captured, belong to 1 families, 3 genera and 5 species; The average density was 39.78 / h per lamp, the lowest density is 0.73/h per lamp, the highest density is 71.9/h per lamp, shows bimodal wavy change; Culex pipiens pallens accounts for 88.59% of the total sum, which is the dominant specie in capital airport. Aedes dorsalis is the rarely seen specie. Pathogen detection were negative. Conclusion The density of adult mosquitoes in capital airport is at high level, Seasonal fluctuation is regularly. There are variations exist in mosquitoes composition of different habitat distribution and average density. Culex pipiens pallens is as absolute dominant specie of the capital airport, should become the key of prevention and control in the future.
