Eastern chipmunks were successfully infected with La Crosse virus by bites of 3 New World strains of Aedes albopictus infected orally or transovarially. The virus was subsequently passed from the chipmunks to Ae. albopictus, POTOSI strain, and Ae. triseriatus. The chipmunks developed viremias of 1-4 days duration and antibody titers were similar in intensity and duration to those reported in chipmunks infected by Ae. triseriatus. After feeding on viremic chipmunks, Ae. albopictus became infected and transmitted La Crosse virus at rates similar to the native vector, Ae. triseriatus. Aedes albopictus transmitted La Crosse virus transovarially to first gonotrophic cycle offspring.
通过叮咬经口感染或经卵感染的3种新大陆白纹伊蚊毒株，东部花栗鼠成功感染了拉克罗斯病毒。随后，该病毒从花栗鼠传播至白纹伊蚊波托西毒株和三带喙库蚊。花栗鼠出现了持续1 - 4天的病毒血症，抗体滴度在强度和持续时间上与报道的经三带喙库蚊感染的花栗鼠相似。在吸食了感染病毒血症的花栗鼠后，白纹伊蚊被感染，并以与本地传播媒介三带喙库蚊相似的速率传播拉克罗斯病毒。白纹伊蚊经卵将拉克罗斯病毒传播给第一个生殖营养周期的后代。
