Little is known about the behaviors of African equatorial rain forest mosquito species and their potential role as sylvatic and bridge-vectors of various pathogens of animal and public health. In 2016 and 2017, the diversity and sources of water supporting immature development of mosquitoes in Talangaye Rainforest (South West Cameroon) before, during and after deforestation were investigated. Mosquito eggs, larvae and pupae were collected from 12 natural, seminatural, and artificial water sources and reared to adults. A total of 595 adult mosquitoes belonging to seven genera and at least 43 species were identified. Culex was the most abundant (56.3%) and was encountered in the majority in bamboo pots. Aedes and Uranotaenia species were mostly found in rock pools, while Anopheles and Hodgesia species solely prefer stream pools. In terms of mosquito abundance, rock pools were the most productive (29.91%) followed by bamboo pots (24.7%). Natural sites such as rock pools, tree holes, and stream pools recorded a greater number of species (S = 21, 14 and 12 respectively). During the rainy season, rock pools (46.23%) and bamboo pots (18.7%) were the most productive water bodies, while in the dry season, bamboo pots (35.71%) and stream pools (35.71%) harbored the most mosquitoes. The disturbed and pristine-like habitats had the greatest number of mosquitoes and breeding sites compared to palm plantation. This study provides some useful data on water sources used for immature development of forest mosquito species in Southwest Cameroon and how some species might adapt to changing landscapes, especially due to deforestation.
关于非洲赤道雨林蚊虫种类的行为及其作为各种动物和公共卫生病原体的野生宿主和桥梁媒介的潜在作用，人们了解甚少。2016年和2017年，对喀麦隆西南部塔朗盖雨林在森林砍伐之前、期间和之后支持蚊虫幼体发育的水源多样性和来源进行了调查。从12个天然、半天然和人工水源收集蚊虫卵、幼虫和蛹，并饲养至成虫。共鉴定出595只成年蚊虫，分属于7个属，至少43个种。库蚊最为常见（56.3%），大多出现在竹筒中。伊蚊和蓝带蚊属物种主要见于岩石池，而按蚊和霍氏蚊属物种只偏好溪流池。就蚊虫数量而言，岩石池的繁殖力最强（29.91%），其次是竹筒（24.7%）。岩石池、树洞和溪流池等天然场所记录的物种数量更多（分别为S = 21、14和12）。雨季期间，岩石池（46.23%）和竹筒（18.7%）是繁殖力最强的水体，而旱季时，竹筒（35.71%）和溪流池（35.71%）中的蚊虫最多。与棕榈种植园相比，受干扰的类似原始栖息地的蚊虫和繁殖场所数量最多。本研究提供了一些有用数据，涉及喀麦隆西南部森林蚊虫种类幼体发育所利用的水源，以及一些物种如何适应景观变化，特别是由于森林砍伐导致的景观变化。
