摘    要:目的 了解和掌握滁州市蚊虫的常见种类、密度和季节消长规律,为有效防控蚊媒传染病提供科学依据。方法 收集整理2011 - 2016 年滁州市采用人工小时法获得的成蚊密度监测数据,分析不同生境、月份、年度蚊虫密度监测结果。结果 2011 - 2016 年共捕获蚊虫8 177只,淡色库蚊为优势种,占捕蚊总数的96.06%,其次是白纹伊蚊(2.87%);捕获蚊虫总密度为9.46只/人工小时,蚊虫年平均密度在2011 - 2013 年间呈下降趋势,但2014 年密度开始逐渐回升,2016年蚊虫密度与2011年相比下降了22.34%;不同生境中,蚊虫密度最高的为城郊结合部居民区,其次为城区居民区和牲畜棚,农户最低,密度依次为 12.27、10.00、9.46和6.00 只/人工小时;各监测点捕获蚊虫总密度季节消长趋势呈双峰曲线,最高峰在6月,次高峰在9月。结论 2011 - 2016年滁州市蚊虫密度总体呈下降趋势,但在2014年后有所回升,应加强蚊虫防治工作。蚊虫密度监测结果和季节消长变化趋势可有效指导城市蚊虫防治工作,应将蚊虫密度监测结果和虫媒传染病进行关联分析,为防治蚊媒传染病提供科学依据。

Abstract:Objective To understand the species composition and seasonal fluctuation of mosquitoes in Chuzhou and provide the scientific basis for the prevention and control of mosquitoes and related infectious diseases. Methods The surveillance data of mosquitoes by the person hour method were collected from 2011 to 2016. The densities of different environments, months, and years were analyzed. Results A total of 8177 adult mosquitoes were captured from 2011 to 2016; Culex pipiens pallens was the dominant species, accounting for 96.06% of all mosquitoes, followed by Aedes albopictus, accounting for 2.87%. The overall average density was 9.49 mosquitoes per person-hour. The density of mosquitoes was decreasing from 2011 to 2013, but increasing afterward with fluctuations. By comparison with 2011, the density decreased by 22.34 percent in 2016. The density of mosquitoes was the highest in the rural-urban fringe zone (12.27), followed by the urban residential area (10.00) and the livestock sheds(9.46). The density of mosquitoes from rural residential areas was the lowest(6.00). The seasonal fluctuation curve was in a bimodal distribution. It showed the first peak in June and the second peak in September. Conclusion The density of mosquitoes totally deceased from 2011 to 2016, but it increased again since 2014. We should make more effort to control mosquitoes. The surveillance results of mosquito density and the trends of its seasonal fluctuation can provide effective guidance for urban mosquito control. It is suggested that we should analyze the association of mosque density with mosquito-borne diseases, so as to provide a scientific basis for the prevention and control of mosquitoes and mosquito borne diseases.
