目的掌握汕头口岸蚊类的种群构成、不同生境密度分布、季节消长及携带病毒情况,为口岸蚊及蚊媒传染病的有效防控提供依据。方法采用诱蚊灯收集法、伊蚊集卵器调查法进行为期半年的调查,采用逆转录-聚合酶链式反应(RT-PCR)方法检测蚊类携带黄病毒属和甲病毒属情况。结果 2014年5-10月捕获成蚊1 529只,经分类鉴定隶属于2亚科3属13种,致倦库蚊为优势蚊种,占总数的52%;全年平均蚊密度为2.36只/h·灯;成蚊季节消长高峰期在5-6月,白纹伊蚊季节消长高峰期在8-9月。结论本次调查得出较为详细的汕头口岸蚊媒本底资料,为今后蚊媒防治工作提供切实的技术指导,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 population structure, density distribution, seasonal fluctuation and virus carrying of mosquitoes in Shantou Port, and provide the basis for the effective prevention and control of mosquito and mosquito-borne diseases. Methods The mosquito lamp was used to collect mosquitoes and the ovoviparous investigation method was used for a half year investigation. The detection of mosquitoes carrying flavivirus and alphavirus by reverse transcription polymerase chain reaction (RT-PCR) was carried out. Results A total of 1 529 adult mosquitoes were captured from May to October in 2014. Among them, 13 species belonging to 3 genera and 2 subfamilies were identified, and Culex quinquefasciatus was the dominant mosquito species, accounting for 52% of the total. The average mosquito density was 2.36 / h · lights; the season of adult mosquito growth and decline in May-June, Ae. albopictus season growth and peak in August-September. Conclusion This investigation leads to a more detailed mosquito-borne background data of Shantou Port, providing practical technical guidance for mosquito-repellent control in the future and establishing a risk analysis system for risk warning and risk management based on the monitoring.
