本研究旨在评估蚊子物种多样性,分布,和Covè的生态偏好,Ouinhi,和Zangnanado公社,贝宁南部。这些信息对于了解蚊子的生物生态和将控制工作集中在媒介传播疾病的高风险地区至关重要。在2020年6月至2021年4月之间,每季度在60个集群中收集蚊子,使用人类着陆捕获物。除了季节性的蚊子丰富,香农的多样性,辛普森,和Pielou的公平指数也进行了评估,以评估蚊子的多样性。使用MaxEnt开发了生态位模型,使用环境变量评估物种分布。总的来说,在所有社区中,雨季的蚊子密度高于旱季。在所有公社中,湿季的香农多样性指数也明显高于旱季(p<0.05)。An的栖息地适宜性。冈比亚s.s.,A.coluzzii,Cx.quinquefasciatus和Ma。非洲受斜坡的影响很大,等温性,站点方面,高程,雨季和旱季的降水季节性。总的来说,根据季节,四种主要蚊子的生态偏好在研究公社之间是可变的。这强调了环境条件对蚊子物种分布的影响。此外,与旱季相比,雨季的蚊子数量更加多样化。
The present study aimed to assess mosquito species diversity, distribution, and ecological preferences in the Covè, Ouinhi, and Zangnanado communes, Southern Benin. Such information is critical to understand mosquito bio-ecology and to focus control efforts in high-risk areas for vector-borne diseases. Mosquito collections occurred quarterly in 60 clusters between June 2020 and April 2021, using human landing catches. In addition to the seasonal mosquito abundance, Shannon\'s diversity, Simpson, and Pielou\'s equitability indices were also evaluated to assess mosquito diversity. Ecological niche models were developed with MaxEnt using environmental variables to assess species distribution. Overall, mosquito density was higher in the wet season than in the dry season in all communes. A significantly higher Shannon\'s diversity index was also observed in the wet season than in the dry seasons in all communes (p < 0.05). Habitat suitability of An. gambiae s.s., An. coluzzii, Cx. quinquefasciatus and Ma. africana was highly influenced by slope, isothermality, site aspect, elevation, and precipitation seasonality in both wet and dry seasons. Overall, depending on the season, the ecological preferences of the four main mosquito species were variable across study communes. This emphasizes the impact of environmental conditions on mosquito species distribution. Moreover, mosquito populations were found to be more diverse in the wet season compared to the dry season.
