作为疟疾流行病学多学科研究的一部分，在斯里兰卡中北部的Huruluwewa流域内的Mahameegaswewa村进行了一项为期13个月的调查，调查了在地表水栖息地繁殖的未成熟按蚊。该流域是古代小型水箱灌溉网络的代表，仍然是低海拔干旱地区水稻生产系统的重要组成部分。从村庄生态系统内的5个幼虫栖息地采集的3，940份样品中，共获得了3，818份未成熟体，代表12个种。culicifaciesGiles是收集到的最丰富的种类。这两个物种的高峰丰度发生在8月至10月。长喙按蚊货车德伍普按蚊和足斑按蚊莱斯特也很丰富，但无论是这两种按蚊还是其他按蚊都没有达到与足斑按蚊、瓦鲁纳按蚊和足斑按蚊相当的丰度。库利西相一个明显的进展，在繁殖栖息地的使用，从河床坦克床和排水区池被认为是在一个。在前季风时期的culicifacies。减少或改变这些生境的环境管理措施可能会减少疟疾的传播。
A 13-mo survey of immature anopheline mosquitoes breeding in surface water habitats was done at Mahameegaswewa village within the Huruluwewa watershed in north central Sri Lanka as part of a multidisciplinary study on malaria epidemiology. The watershed is representative of the ancient small tank-based irrigation network that still forms an important component of the rice production system in the low elevation dry zone. Tn total, 3,818 immatures representing 12 species were obtained from 3,940 samples taken from 5 larval habitats within the village ecosystem, Anopheles varuna Iyengar and An. culicifacies Giles were the most abundant species collected. Peak abundance in both species occurred in August-October. Anopheles barbirostris Van der Wulp and An, peditaeniatus Leicester also were abundant, but neither these nor the other anophelines attained comparable abundance to An, varuna and An. culicifacies. A clear progression in breeding habitat use from stream bed to tank bed and drainage area pools was seen in An. culicifacies during the premonsoon period. Environmental management measures to reduce or modify these habitats could potentially decrease malaria transmission.
