Climatic and landscape patterns have been associated with both relative mosquito abundance and transmission of mosquito-borne illnesses in many parts of the world, especially warm and tropical climes. To determine if temperature, precipitation, or degree of urbanization were similarly important in the number of potential mosquito vectors for West Nile virus in the moderately temperate climate of western Washington, mosquitoes were collected using CDC carbon-dioxide/light traps set throughout the Seattle region during the summers of 2003 and 2004. The type and abundance of recovered species were compared to ecological correlates. Temperature and mosquito abundance were positively correlated, while precipitation was not strongly correlated with numbers of mosquitoes. Potential WNV mosquito vectors were most abundant in urban and suburban sites, including sites near communal roosts of American crows (Corvus brachyrhynchos). Exurban sites had the greatest vector species diversity, and Culex pipiens was the most abundant species throughout the region.
在世界许多地区，尤其是温暖和热带气候地区，气候和景观格局与蚊子相对丰度以及蚊媒疾病传播都存在关联。为了确定在华盛顿州西部温和的温带气候中，温度、降水或城市化程度对西尼罗河病毒潜在蚊媒数量是否同样重要，于2003年和2004年夏季，在西雅图地区各处使用疾控中心二氧化碳/灯光诱捕器收集蚊子。将捕获物种的类型和丰度与生态相关因素进行比较。温度与蚊子丰度呈正相关，而降水与蚊子数量的相关性不强。西尼罗河病毒潜在蚊媒在城市和郊区地点最为丰富，包括靠近美洲乌鸦（短嘴鸦）群居栖息地的地点。远郊地区的蚊媒物种多样性最高，整个地区致倦库蚊是最丰富的物种。
