Experimental studies compared the vector competence of Aedes sollicitans (Skuse) and Ae. taeniorhynchus (Wiedemann) collected on Assateague Island, Va., for an epizootic strain (Trinidad donkey) of Venezuelan equine encephalomyelitis (VEE) virus. Infection rates were significantly higher in Ae. sollicitans (101/107, 94%) than in Ae. taeniorhynchus (103/175, 59%), even though both species fed concurrently on the same infected hamsters. Similarly, dissemination and transmission rates were significantly higher in the Ae. sollicitans population tested. Although both Ae. taeniorhynchus and Ae. sollicitans are natural vectors of VEE virus, the latter species should be considered a more efficient vector of VEE epizootic strains, based on its greater susceptibility to infection and higher transmission rates.
实验研究比较了在弗吉尼亚州阿萨蒂格岛采集的骚扰伊蚊（Skuse）和带喙伊蚊（Wiedemann）对委内瑞拉马脑炎（VEE）病毒的一种 epizootic 株（特立尼达驴株）的媒介能力。骚扰伊蚊的感染率（101/107，94%）显著高于带喙伊蚊（103/175，59%），尽管这两个物种同时叮咬相同的受感染仓鼠。同样，在测试的骚扰伊蚊种群中，传播率和传染率也显著更高。虽然带喙伊蚊和骚扰伊蚊都是 VEE 病毒的自然媒介，但基于后者对感染的更高易感性和更高的传播率，应将其视为 VEE epizootic 株更有效的媒介。
