摘　　要：目的调查武汉市2006-2009年成蚊种群构成和季节消长情况,为蚊虫及流行性乙型脑炎的防治工作提供科学依据。方法诱蚊灯法。结果 4年捕获蚊虫1科4属6种,共151 116只,城区致倦库蚊为优势种,占城区蚊虫总数的99.9%,农村三带喙库蚊为优势种,占农村蚊虫总数的62.3%。每年季节消长情况相似,密度高峰一般在6～8月;1～3月和11～12月成蚊密度很低,4年平均密度指数呈递减趋势。结论致倦库蚊为城区优势种,三带喙库蚊为农村优势种,种群构成和季节消长无明显变化,全市4～10月可开展蚊虫防治工作。Objective To investigate the species composition and seasonal growth and decay trend of adult mosquito in Wuhan in 2006-2009,and provide scientific basis for mosquito control and epidemic encephalitis B prevention.Methods Lamp baited trap method.Results Totally 151 116 mosquitoes were trapped,including 6 species distributed in 4 genera under 1 family during four years.The dominant species was Culex pipiens quinquefasciatus in Wuhan urban area,accounted for 99.9%,while Culex tritaeniorhynchus in rural area for 62.3%.The investigation showed similar results of seasonal growth and decay trend of mosquito every year.Mosquito density reached high peak between June to August,of which was very weak from January to March,November to December,but the rate of the average appeared descend trend.Conclusion Cx.tritaeniorhynchus was the dominant species in rural area,and Cx.pipiens quinquefasciatus was the dominant species in urban area.No obvious changes could be found with the species composition and the seasonal growth of mosquito.So mosquito control can be carried out from April to October in Wuhan.
