测量蚊媒的存活率和传播率是设计和实施控制策略的重要步骤。病媒生存在决定病原体传播强度方面起着关键作用，而病媒的运动决定了控制努力必须在多大的空间尺度上发挥作用。我们首次估计了淡色库蚊在北美的野外存活率和传播率，库蚊是西尼罗河病毒(WNV)的重要地方性和桥梁媒介。我们连续两年在华盛顿特区附近的一个居民区进行了标记-释放-重新捕获研究，并将非线性回归模型与重新捕获数据进行拟合，将天气信息纳入生存和重新捕获概率。我们发现，两年间的每日存活率没有显着差异，但受到降雨的负面影响。日存活率为0.904±0.037(SE)，平均寿命为10.4d。与其他媒介传播的病原体一样，测量的存活率表明，在我们的地点，大多数感染西尼罗河病毒的Cx。蚊子可能会在感染之前死亡(能够将西尼罗河病毒传播给宿主)。我们在释放后的最初一晚发现了相对较少的驱散证据。我们的结果表明，西尼罗河病毒和其他病原体的传播是由Cx传播的。蚊子可能是高度地方性的，它们强调了影响蚊媒生存的因素的重要性。
Measurement of the survival and dispersal rates of mosquito vectors is an important step in designing and implementing control strategies. Vector survival plays a key role in determining the intensity of pathogen transmission, and vector movement determines the spatial scale on which control efforts must operate to be effective. We provide the first estimates of field survival and dispersal rates for Culex pipiens in North America, an important enzootic and bridge vector for West Nile virus (WNV). We conducted mark-release-recapture studies in a residential area near Washington DC in two consecutive years and fit nonlinear regression models to the recapture data that incorporate weather information into survival and recapture probabilities. We found that daily survival rates were not significantly different between the two years but were negatively affected by rainfall. The daily survival rate was 0.904 ± 0.037 (SE), which implies an average longevity of 10.4 days. As with other vector-borne pathogens, the measured survival rate suggests that at our site the majority of WNV-infected Cx. pipiens mosquitoes may perish before becoming infectious (being able to transmit WNV to hosts). We found relatively little evidence of dispersal following the initial night after release. Our results suggest that transmission of WNV and other pathogens transmitted by Cx. pipiens may be highly local and they highlight the importance of factors that influence survival of mosquito vectors.
