目的了解福建省不同地区白纹伊蚊种群密度及生态特征,为评估登革热传播风险,预防和控制登革热暴发流行提供依据。方法调查不同地区白纹伊蚊幼虫密度;调查居民室内外积水容器的种类和幼虫孳生情况。结果白纹伊蚊平均布雷图指数(breteau index,BI)、房屋指数(house index,HI)和容器指数(container index,CI)分别为84.5、46.9和43.1;莆田涵江、福州连江、厦门集美、漳州东山、宁德福鼎和南平武夷山的布雷图指数分别为73.1、109.5、87.3、74.7、63.1和61.9;幼虫孳生地类型以废弃的缸、罐、桶、碗等闲置容器为主。结论福建省登革热媒介白纹伊蚊幼虫密度大大超过登革热流行高危险指数,存在登革热暴发流行的风险。“,”Objective To understand the density and ecological characteristics of aedes albopictus and provide basis for evaluating the communication risk of dengue and controlling the outbreak of dengue.Method Investigate the density of aedes albopictus in different regions,as well as the types of water containers and the breeding situation of larvae in home.Results The average breteau index(BI),house index(HI) and container index(CI) of aedes albopictus were 84.5,46.9 and 43.1,respectively;and the BI in Hanjiang,Lianjiang,Jimei,Dongshang,Fuding and Wuyishan were 73.1,109.5,87.3,74.7,63.1 and 61.9,respectively.The breeding places of larva were mainly in waste vat,can,barrel and bowl and othee idle containers.Conclusions In FuJian,the density of aedes albopictusb was high,thus there existed risks of dengue.
