2009年汶川地震极重灾区蚊密度监测分析
|
摘要
目的掌握汶川地震极重灾区蚊类的种群构成和不同生境的蚊密度情况,为做好蚊媒传染病的风险评估,指导开展汶川地震灾区蚊类和相关传染病的防控工作提供可靠依据。方法采用诱蚊灯法诱捕成蚊,并对捕获蚊虫进行分类鉴定。结果四川省汶川地震极重灾区蚊虫总密度为1.64只(/灯.h),蚊种构成以致倦库蚊数量最多,占捕获总数的64.53%,三带喙库蚊和中华按蚊分别占15.69%和10.77%;各类生境密度以安置区和中心城区较高,地震遗址较低;季节消长显示,6-8月是灾区蚊虫的高峰期。结论蚊虫总密度较低,其中安置区和中心城区应作为开展综合防治的重点区域;通过开展系统的蚊密度监测工作,科学指导汶川地震灾区蚊类的综合防治,防止了相关传染病的暴发流行。
Objective To determine the population constitution and density of mosquitoes in different habitats in the worst-hit areas of earthquake-stricken Wenchuan to inform risk evaluation,prevention and control of mosquito-borne disease.Methods Light traps were applied to collect adult mosquitoes,followed by classification and identification.Results The mosquito density was 1.64 per light per hour.The population consisted of Culex pipiens quinquefasciatus mostly,which accounted for 64.53% of the total number.Cx.tritaeniorhynchus and Anopheles sinensis accounted for 15.69% and 10.77%,respectively.The mosquito density in settlement residences and central city was higher than that in earthquake ruins.An upward trend from June to August was shown from the seasonal fluctuation.Conclusion The overall density of mosquitoes was low.However,integrated management is still needed for the settled communities and central city in combination with systematic monitoring to prevent potential outbreaks of related infectious diseases.
