Vector competence of Aedes (Ae.) vexans nipponii (nip.) and Culex (Cx) tritaeniorhynchus for Getah virus was compared after incubation at 28 degrees C and 20 degrees C. Marked differences existed between Ae. vexans nip. strains Sapporo and Cx tritaeniorhynchus strain Kyoto in infection and transmission rates following ingestion of blood meals containing several concentrations of Getah virus. Simultaneous comparison of infectivity also revealed that infection rates of Ae. vexans nip. strains Sapporo (74%) and Shizunai (68%) were higher than those of Cx tritaeniorhynchus strain Kyoto (44%). No significant differences were seen in infection rates between three strains of Cx tritaeniorhynchus or between two strains of Ae. vexans nip. Getah virus propagated and was transmitted in Ae. vexans nip. as rapidly at 20 degrees C as at 28 degrees C. Following seven days' incubation both at 20 degrees C and 28 degrees C, Ae. vexans nip. was capable of transmitting the virus. 14 days' incubation at 20 degrees C were needed for Cx tritaeniorhynchus to acquire the same capability. Ae. japonicus, Ae. aegypti, Ae. albopictus, Cx pipens pallens, Armigeres subalbatus and Tripteroides bambusa were also susceptible to Getah virus infection.
在28摄氏度和20摄氏度下孵育后，比较了刺扰伊蚊（Aedes (Ae.) vexans nipponii (nip.)）和三带喙库蚊（Culex (Cx) tritaeniorhynchus）对Getah病毒的媒介能力。刺扰伊蚊的札幌株和三带喙库蚊的京都株在摄取含有几种浓度Getah病毒的血餐后，感染率和传播率存在显著差异。感染性的同时比较还显示，刺扰伊蚊的札幌株（74%）和知床株（68%）的感染率高于三带喙库蚊的京都株（44%）。三带喙库蚊的三个株系之间或刺扰伊蚊的两个株系之间的感染率没有显著差异。Getah病毒在刺扰伊蚊中传播并能在20摄氏度和28摄氏度下同样迅速地传播。在20摄氏度和28摄氏度下孵育7天后，刺扰伊蚊能够传播病毒。三带喙库蚊需要在20摄氏度下孵育14天才能获得相同的能力。日本伊蚊、埃及伊蚊、白纹伊蚊、淡色库蚊、骚扰阿蚊和竹生杵蚊也易感染Getah病毒。
