本研究调查了孟加拉国达卡市的家庭风险因素以及未成熟埃及伊蚊和白纹伊蚊的患病率、丰度和分布，及其与城市区域和家庭层面的社会经济和生态因素的关系。 2011年季风期间，对12个随机选择的行政区的826户家庭进行了病媒蚊调查。结果表明，未成熟白藜芦醇的丰度和分布。埃及伊蚊和伊蚊。在不同社会经济地位的地区，白纹伊蚊和人均蛹指数没有显着差异。在已识别的 35 种不同类型的潮湿容器中，有 30 种受到感染，在 23 种蛹阳性容器类型中，有 9 种被定义为蛹“生产力最高”，包括：一次性塑料容器（550 个容器中的 12.2%）、可密封塑料桶（12.0%）、轮胎（10.4%）、废弃塑料桶（9.6%）、花盆和托盘（8.5%）、冰箱托盘（6.5%）、塑料瓶（6.4%）、陶罐（4.9%）和水箱（1.6%）。在评估容器的功能时，发现装饰性、废弃以及家庭维修和重建相关的容器类别与家庭中的蛹数量显着相关。储存水的目的和收入变量是拥有被媒介蚊子侵染的容器的重要预测因素。
This study examined household risk factors and prevalence, abundance, and distribution of immature Aedes aegypti and Aedes albopictus, and their association with socioeconomic and ecological factors at urban zonal and household levels in the city of Dhaka, Bangladesh. During the 2011 monsoon, 826 households in 12 randomly selected administrative wards were surveyed for vector mosquitoes. Results revealed that the abundance and distribution of immature Ae. aegypti and Ae. albopictus, and pupae-per-person indices did not vary significantly among the zones with varied socioeconomic status. Of 35 different types of identified wet containers, 30 were infested, and among the 23 pupae-positive container types, nine were defined as the “most productive” for pupae including: disposable plastic containers (12.2% of 550), sealable plastic barrels (12.0%), tires (10.4%), abandoned plastic buckets (9.6%), flower tub and trays (8.5%), refrigerator trays (6.5%), plastic bottles (6.4%), clay pots (4.9%), and water tanks (1.6%). When the function of the containers was assessed, ornamental, discarded, and household repairing and reconstruction-related container categories were found significantly associated with the number of pupae in the households. The purpose of storing water and income variables were significant predictors of possession of containers that were infested by vector mosquitoes.
