To evaluate the vector competence of Culex tarsalis Coquillett for West Nile virus (WN), females reared from larvae collected in Huntington Beach, Orange County, CA, were fed on 2-3-day-old chickens previously inoculated with a New York strain (Crow 397-99) of WN. The Cx. tarsalis mosquitoes were efficient laboratory vectors of WN, with estimated transmission rates of 81% and 91% for mosquitoes that ingested 10(6.5) or 10(7.3) plaque-forming units of WN/mL of blood, respectively. Based on efficiency of viral transmission and the role of this species in the transmission of the closely related St. Louis encephalitis virus, Cx. tarsalis should be considered a potentially important vector of WN in the western United States.
为评估致倦库蚊对西尼罗河病毒(WN)的媒介能力,从加利福尼亚州橙县亨廷顿海滩采集的幼虫饲养出的雌性致倦库蚊,被喂食给先前接种了WN纽约株(Crow 397 - 99)的2 - 3日龄雏鸡。致倦库蚊是WN高效的实验室传播媒介,分别摄入每毫升血液含10(6.5)或10(7.3)个空斑形成单位WN的蚊子,其估计传播率分别为81%和91%。基于病毒传播效率以及该物种在密切相关的圣路易斯脑炎病毒传播中的作用,致倦库蚊应被视为美国西部WN的潜在重要传播媒介。
