2011～2014年华东四地区口岸蚊类监测报告

目的]掌握华东四地区口岸蚊类种群构成、分布、密度、季节消长和携带病原体情况,为蚊类的口岸防治提供基础数据.方法]采用CO2诱蚊器、集卵器法、捞勺法、目测法对华东四地区口岸蚊类进行调查,对捕获蚊类进行分类鉴定和病原体检测.结果]2011～2014年本底共捕获蚊类102 583只,隶属于1科6属18种,以致倦库蚊/淡色库蚊为优势种.5～10月均可捕获蚊类,以6月为高峰者最多.集卵器法阳性率为9.41％,孳生地阳性率为7.23％.入境截获蚊类数量较少,以淡色库蚊为主.登革热、疟疾等病原体检测均为阴性.结论]华东四地区口岸以致倦库蚊/淡色库蚊为优势种,6月为高峰,口岸存在蚊类孳生环境,应在今后的防控工作中作为重点对象.

Monitoring Report on Mosquitoes at Ports of Four Regions in East China during 2011-2014

Objective] The aim was to understand the species composition,distribution,density,seasonal fluctuation and pathogens of mosquitoes in four regions of East China to provide basic data for prevention and control of mosquitoes at ports.Method] The mosquitoes at 21 ports of four regions in East China were investigated during 2011-2014 by CO2 lamp method,egg collection method,scoop method and visual method.The species of mosquitoes was identified,and pathogens in mosquitoes were detected.Result] From 2011 to 2014,102 583 mosquitoes were captured at the ports,belonging to 18 species,6 genera and 1 family.Culex pipiens quinquefasciatus or Culex pipiens pallens was the dominant species at most ports.Mosquitoes could be captured from May to October,and the captured mosquitoes were the most in June.The positive rate of egg collectors was 9.41％,and the positive rate of breeding places was 7.23％.Rare entry mosquitoes were captured,and most of them were C.pipiens pallens.The detection results of dengue fever,malaria and other pathogens were negative.Conclusion] C.pipiens quinquefasciatus or C.pipiens pallens was dominant at most ports,and the peak period was June.There were breeding environments of mosquitoes at some ports,so the prevention and control of mosquitoes at these ports should be paid more attention to in future.
