Mosquito larvae were collected from the subalpine region of the eastern Sierra Nevada Mountains from 2011 to 2014. Two watersheds were sampled and sites selected were mainly vernal snow‐melt pools and wet meadows. Seven Aedes species, Culiseta incidens (Thomson), and Culex tarsalis Coquillett were collected. The most abundant and widely distributed species were Ae. hexodontus Dyar and Ae. tahoensis Dyar. Aedes tahoensis was the predominate species in woodland snow‐melt habitats. Some species were found at most elevations while others were found more often at specific elevations. The most restrictive species was Ae. ventrovittis Dyar which occurred almost exclusively between 3,219 m a.s.l. and 3,390 m a.s.l. Shannon and Simpson species diversity indices demonstrated that species diversity was greater in meadow habitats compared to woodland habitats. Mixed woodland/meadows, rock pools, and shallow grass pools were intermediate in species diversity. Abiotic factors such as snowpack and water temperature impacted species development times and when habitats dried. It was concluded that spatial and temporal patterns of habitats, along with elevation, influenced species presence and larval development. The results of the present study and previous work in the eastern Sierras will help guide future research that focuses on the potential change in the distribution and seasonality of subalpine mosquitoes and disease potential in the eastern Sierras as climatic conditions change.

美国内华达山脉东部亚高山带的蚊虫幼虫（双翅目：era科）的生态学

2011年至2014年从内华达山脉东部的亚高山地区收集了蚊虫幼虫。对两个流域进行了采样，选择的地点主要是春季融雪池和湿草甸。收集了七种伊蚊，Culiseta incidens（Thomson）和库蚊（Culex tarsalis Coquillett）。最丰富和分布最广的物种是Ae。hexodontus Dyar和Ae。tahoensis Dyar。tahoensis是在林地融雪栖息地中的主要物种。在大多数海拔发现了一些物种，而在特定海拔发现了更多物种。限制性最强的物种是Ae。腹膜炎Dyar几乎仅在3,219 m asl和3,390 m asl之间发生。Shannon和Simpson物种多样性指数表明，与林地生境相比，草甸生境中物种多样性更大。林地/草甸混合地，岩池和浅草池在物种多样性中处于中等水平。积雪和水温等非生物因素影响物种的发育时间以及栖息地干燥的时间。结论是，生境的时空格局以及海拔高度会影响物种的存在和幼体的发育。本研究的结果和先前在塞拉利昂东部开展的工作将有助于指导今后的研究，该研究的重点是随着气候条件的变化，亚高山蚊子的分布和季节性的潜在变化以及塞拉利昂东部的疾病潜力。
