Abstract
LaCrosse virus (California encephalitis group) was recovered from F1 eggs, larvae, and adults produced by experimentally infected Aedes triseriatus. The F1 females transmitted the virus by bite to suckling mice and chipmunks. This, plus isolations of LaCrosse virus from larvae collected from their natural habitats in enzootic areas and from males and females reared from them, suggests that transovarial transmission is the overwintering mechanism for this arbovirus in northern United States.Keywords
