Cohorts of Culex adults were marked uniquely with date- and site-specific fluorescent dust colors and were released at centrally located residences and at peripheral breeding sources to study population dispersal, size, additions, and deletions. The recapture rate of Cx. quinquefasciatus females was higher and the mean distance dispersed was lower in residential than in agricultural or park habitats. Dispersal was associated with host-seeking activity and ranged from 0.6 to 1.0 km/d. Survivorship ranged from 0.65 to 0.84 per day, and population density ranged from 36,612 to 671,634 females per km2. The sampling efficiency of CO2-baited traps in residential habitats increased coincidentally with increasing population density. Gravid traps were most effective in residential habitats where there were few competitive oviposition sites. Teneral Cx. stigmatosoma were extremely dispersive, and few marked females were recaptured. Unmarked females were more abundant at CO2-baited traps in residential habitats than at traps near productive peripheral breeding sources. Few Cx. tarsalis were released, and the recapture rate in residential habitats was low when compared with rural sites.
库蚊成虫群体用特定日期和地点的荧光粉尘颜色进行独特标记，然后在位于中心的住所和周边繁殖源释放，以研究种群扩散、规模、增减情况。在居民区，致倦库蚊雌蚊的再捕获率较高，平均扩散距离较短，而在农业或公园栖息地则相反。扩散与寻找宿主的活动有关，范围为每天0.6至1.0公里。每日存活率在0.65至0.84之间，种群密度为每平方公里36,612至671,634只雌蚊。在居民区，二氧化碳诱捕器的采样效率随着种群密度的增加而同步提高。孕蚊诱捕器在竞争性产卵场所较少的居民区最为有效。新羽化的污跗库蚊极具扩散性，很少有标记雌蚊被重新捕获。在居民区，未标记的雌蚊在二氧化碳诱捕器处比在高产周边繁殖源附近的诱捕器处更为常见。释放的西方马脑炎病毒媒介蚊很少，与农村地区相比，在居民区的再捕获率较低。
