Deforestation is a major threat to biodiversity but little data exist on how deforestation in real‐time affects the overall mosquito species community despite its known role in the transmission of diseases. We compared the abundance and diversity of Culex mosquitoes before and after deforestation along a gradient of three different anthropogenic disturbance levels in a tropical rainforest in southwestern Cameroon. The collections were conducted in unlogged forest (January, 2016), selectively logged forest (January, 2017), and within a young palm plantation (October, 2017) using net traps, sweep nets, resting traps, and dipping for immature stages in water bodies. Mosquitoes were morphologically identified to subspecies, groups, and species. A total of 2,556 mosquitoes was collected of which 1,663 (65.06%) belong to the genus Culex, (n=427 (25.68%) in the unlogged forest; n=900 (54.12%) in the selectively logged forest; and n=336 (20.2%) in the young palm plantation) with a significant difference among the habitats. Diversity and richness of mosquitoes varied significantly among habitats with the highest values found in the selectively logged forest (H=2.4; DS=0.87; S=33) and the lowest value in the unlogged forest (H=1.37; DS=0.68; S=13). The results of this study showed that deforestation affects the abundance and diversity of Culex mosquitoes and favors the invasion of anthropophilic mosquitoes. Higher mosquito abundance and diversity in the selectively logged forest than in the pristine forest is notable and some explanations for these differences are discussed.

毁林对喀麦隆西南热带雨林中库蚊的数量，多样性和丰富度的影响。

森林砍伐是对生物多样性的主要威胁，但是尽管森林砍伐在疾病传播中起着众所周知的作用，但几乎没有关于实时森林砍伐如何影响整个蚊子群落的数据。我们比较的丰富性和多样性库蚊喀麦隆西南部热带雨林中，森林砍伐前后的蚊子沿三种不同的人为干扰水平梯度变化。收集工作是在未砍伐的森林（2016年1月），选择性砍伐的森林（2017年1月）和年轻的棕榈人工林（2017年10月）内进行的，使用网捕器，扫网，静息捕集器和浸入水中的未成熟阶段进行。身体。蚊子在形态上被识别为亚种，种群和物种。总共收集了2556个蚊子，其中1663个（65.06％）属于库蚊属，（在未砍伐的森林中，n = 427（25.68％）；在有选择伐木的森林中，n = 900（54.12％）；在年轻的棕榈种植园中，n = 336（20.2％）），生境之间存在显着差异。蚊子的多样性和丰富度在生境中差异很大，在选择性砍伐的森林中发现的最高值（H = 2.4； DS = 0.87； S = 33），在未砍伐的森林中发现的最低值（H = 1.37； DS = 0.68； S = 13）。这项研究的结果表明，森林砍伐影响库克斯蚊的数量和多样性，并有利于嗜人蚊的入侵。与原始森林相比，选择性伐木森林中蚊子的丰度和多样性更高，并且对这些差异进行了一些解释。
