LaCrosse virus (California encephalitis group) was recovered from F(1) eggs, larvae, and adults produced by experimentally infected Aedes triseriatus. The F(1) 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.
从实验感染的三带喙库蚊所产的F(1)代卵、幼虫和成虫中分离出了拉克罗斯病毒（加利福尼亚脑炎病毒群）。F(1)代雌蚊通过叮咬将病毒传播给乳鼠和花栗鼠。此外，从地方性流行区自然栖息地采集的幼虫以及由这些幼虫培育出的雄蚊和雌蚊中也分离出了拉克罗斯病毒，这表明经卵传播是这种虫媒病毒在美国北部的越冬机制。
