武夷山登革热媒介监测结果分析

目的：开展登革热媒介监测，预防和控制登革热暴发性流行。方法：调查武夷山机场及其毗邻居民村、度假区等环境媒介种类与滋生习性，以布雷图指数计算幼虫种群密度。结果：本调查仅查获白纹伊蚊，未发现埃及伊蚊。机场、居民村、度假区白纹伊蚊的布雷图指数分别为15．91、8．90和53．26，其中毗邻机场的旧居民点赤石村布雷图指数高达109．26，是新居民点双利村的5倍。发现白纹伊蚊阳性积水容器13种，机场生活区的阳性积水容器主要为快餐盒和电器包装盒；居民村主要为旧缸罐等容器型积水；度假区主要为旧轮胎和假山积水。结论：武夷山旧居民村白纹伊蚊种群密度明显较新村、机场和度假区为高。
