摘要
目的掌握沙河阅兵村及周边地区蚊虫种群的本底情况,评价防治效果。方法采用CO2灯诱法,将捕获成蚊分类鉴定,同时采取以环境治理为基础、化学防治为重点的综合措施杀灭蚊虫。结果 2009年3-10月共捕获成蚊8351只,其中淡色库蚊、中华按蚊、白纹伊蚊、三带喙库蚊分别占捕蚊总数的99.57%、0.19%、0.18%和0.06%,淡色库蚊为绝对优势种。蚊虫于5月初开始出现,6-7月为高峰期,9月底基本消失;主要栖息在阅兵村周边的小树林和杂草丛,阅兵村内蚊虫密度较低;可传播的疾病有流行性乙型脑炎等。结论基本掌握了沙河阅兵村蚊虫的优势种群、季节变化、场所分布等本底情况及其潜在危害,所采取的综合防治措施简便有效,对在该地域进行大规模军事活动的防疫保障有指导意义,对部队大规模集结条件下的蚊虫防治有参考价值。
Objective To identify the mosquito populations and evaluate the control effects in Yuebing village and the surrounding areas of Shahe,Beijing.Methods Mosquitoes were captured using CO2 light traps and subject to taxonomic identification.Comprehensive control measures based on environmental management and chemical approaches were employed to kill mosquitoes.Results From March to October 2009,8351 adult mosquitoes were captured,of which Culex pipiens pallens,Anopheles sinensis,Aedes albopictus and Cx.tritaeniorhynchus accounted for 99.57%,0.19%,0.18% and 0.06%,respectively.Cx.pipiens pallens was the predominant species.The mosquitoes emerged in early May,peaked in June and July,and generally disappeared by the end of September,mainly dwelling in woods and weeds surrounding the village.However,the mosquito density was relatively low in the village.The comprehensive control measures were simple and effective against mosquitoes.Conclusion The predominant species,seasonal dynamics and geographic distribution of mosquitoes in Yuebing village as well as the potential hazards were basically identified,which was of guiding value for anti-epidemic strategies in large-scale military activities in this region and for mosquito prevention and control in large-scale military assembly.
