Abstract：
Mosquitoes (Diptera: Culicidae) are one of the most impactful pests to human society, both as a nuisance and a potential vector of human and animal pathogens. Mosquito larvae develop in still aquatic environments. Eliminating these habitats near high human density or managing them to reduce the suitability for mosquitoes will reduce mosquito populations in these human environments and decrease the overall negative impact of mosquitoes on humans. One common source of standing water in urban and suburban environments is the water that pools in stormwater control measures. Previous studies have shown that some stormwater control measures generate large numbers of mosquitoes while others harbor none, and the reason for this difference remains unclear. Our study focuses on elucidating the factors that cause a stormwater control measure to be more or less suitable for mosquitoes. During the summers of 2021 and 2022, we collected and identified mosquito larvae from thirty stormwater control measures across central Ohio to assess variation in mosquito abundance and diversity among sites. Our goal was to determine if specific types of stormwater control measures (retention ponds, detention ponds, or constructed wetlands) harbored different abundances of mosquitoes or different community structures. We also assessed environmental parameters of these sites to elucidate their effects on mosquito abundance and diversity. Overall, we recorded the highest number of mosquito larvae and species in constructed wetlands. However, these sites were dominated by the innocuous species, Culex territans. Conversely, detention ponds held fewer mosquitoes but a higher proportion of known vector species, including Culex pipiens and Aedes vexans. The total number of mosquitoes across all sites was correlated with higher vegetation, more shade, lower water temperatures, and lower pH, suggesting stormwater control measures with these features may also be hotspots for mosquito proliferation.
摘要：
蚊子（双翅目：Culicidae）是对人类社会影响最大的害虫之一，作为人类和动物病原体的滋扰和潜在媒介。蚊子幼虫在静止的水生环境中发育。消除这些接近人类高密度的栖息地或管理它们以减少对蚊子的适应性将减少这些人类环境中的蚊子种群并减少蚊子对人类的总体负面影响。在城市和郊区环境中，积水的一个常见来源是雨水控制措施中的积水。先前的研究表明，一些雨水控制措施会产生大量蚊子，而另一些则没有蚊子，这种差异的原因尚不清楚。我们的研究重点是阐明导致雨水控制措施或多或少适合蚊子的因素。在2021年和2022年的夏季，我们从俄亥俄州中部的30种雨水控制措施中收集并鉴定了蚊子幼虫，以评估不同地点的蚊子丰度和多样性的变化。我们的目标是确定特定类型的雨水控制措施(保留池，拘留池,或人工湿地）拥有不同数量的蚊子或不同的群落结构。我们还评估了这些地点的环境参数，以阐明它们对蚊子丰度和多样性的影响。总的来说,我们在人工湿地中记录到最多的蚊子幼虫和物种。然而,这些地点以无害物种为主，库蚊。相反，拘留池的蚊子较少，但已知媒介物种的比例较高，包括淡色库蚊和伊蚊。所有地点的蚊子总数与较高的植被相关，更多的阴影，较低的水温，更低的pH值，提示具有这些特征的雨水控制措施也可能是蚊子扩散的热点。
