Overhead tank is the potential breeding habitat of Anopheles stephensi in an urban transmission setting of Chennai, India

A year-long, weekly study was conducted in Chennai to inspect available clear/clean water mosquito breeding habitats. Different breeding features, such as instar-wise, immature density and co-inhabitation with other mosquito species, were analysed. The characteristics of breeding habitats, i.e., type of habitat, water temperature and presence of aquatic organisms, organic matter and green algal remnants on the water surface at the time of inspection, were also studied. Immature density of vector was correlated with presence of other mosquito species, malaria prevalence, habitat characteristics and monthly/seasonal fluctuations. All the data collected from field observations were analysed using standard statistical tools. (MapVEu VBP0000182)

本研究于金奈（Chennai）开展了为期一年的每周监测工作，以调查可获取的洁净水源蚊虫滋生栖息地。研究分析了多项蚊虫滋生特征，包括按龄期划分的幼虫密度、与其他蚊虫物种的共栖情况等。同时还对滋生栖息地的自身特征展开了调研，涵盖栖息地类型、水体温度、巡查时水体表面的水生生物、有机质及绿色藻类残体的存在状态。此外还将媒介蚊虫的幼虫密度与其他蚊虫物种的存在情况、疟疾流行率、栖息地特征以及月度与季节波动情况进行了相关性分析。所有野外观测采集得到的数据均采用标准统计工具进行分析处理。(MapVEu VBP0000182)
