To identify potential sylvatic, urban and bridge-vectors that can be involved in current or future virus spillover from wild to more urbanised areas, entomological field surveys were conducted in rural, peri-urban and urban areas spanning the rainy and dry seasons in western Cameroon. A total of 2650 mosquitoes belonging to 37 species and eight genera were collected. Mosquito species richness was significantly influenced by the specific combination of the habitat type and the season. The highest species richness was found in the peri-urban area (S = 30, Chao1 = 121 ± 50.63, ACE = 51.97 ± 3.88) during the dry season (S = 28, Chao1 = 64 ± 25.7, ACE = 38.33 ± 3.1). and ( were only found in the rural and peri-urban areas, while s.l. and were only found in the urban area. spp., and were caught in the three habitat types. Importantly, approximately 52% of the mosquito species collected in this study have been implicated in the transmission of diverse arboviruses. This entomological survey provides a catalogue of the different mosquito species that may be involved in the transmission of arboviruses. Further investigations are needed to study the vectorial capacity of each mosquito species in arbovirus transmission.
为了确定可能参与当前或未来病毒从野生环境向城市化程度更高地区溢出的潜在森林、城市和桥梁传播媒介，在喀麦隆西部跨越雨季和旱季的农村、城郊和城市地区开展了昆虫学实地调查。共收集到2650只蚊子，分属于37个物种和8个属。蚊子物种丰富度受栖息地类型和季节的特定组合显著影响。在旱季，城郊地区的物种丰富度最高（物种数S = 30，Chao1指数 = 121 ± 50.63，ACE指数 = 51.97 ± 3.88），雨季时（物种数S = 28，Chao1指数 = 64 ± 25.7，ACE指数 = 38.33 ± 3.1）。[此处原文缺失部分内容]仅在农村和城郊地区被发现，而[此处原文缺失部分内容]复合体和[此处原文缺失部分内容]仅在城市地区被发现。[此处原文缺失部分内容]物种、[此处原文缺失部分内容]和[此处原文缺失部分内容]在三种栖息地类型中均有捕获。重要的是，本研究收集的蚊子物种中约52%与多种虫媒病毒的传播有关。这项昆虫学调查提供了一份可能参与虫媒病毒传播的不同蚊子物种的目录。需要进一步调查以研究每种蚊子在虫媒病毒传播中的媒介能力。
