研究了环境温度对尖音库蚊（Culex pipiens（L.）裂谷热（RVF）幼虫饲养温度（13，17，19，或26摄氏度）没有影响成年女性铬的易感性。感染裂谷热病毒。相比之下，成年人在病毒血症血餐后保持体温会影响雌性的感染率。当蚊子在较低的温度下（13摄氏度（10%），17摄氏度（20%）和19摄氏度（41%））时，含有可检测到的病毒的蚊子明显少于在较温暖的温度下（28摄氏度）（91%）。对于保持在13摄氏度，然后切换到26摄氏度的蚊子，感染率随着26摄氏度时间的增加而稳步增加。在成年雌性动物中检测裂谷热病毒的能力没有受到影响，在它们第一次被置于较高的温度（26摄氏度）之后，又被置于较低的温度（17摄氏度）。在节肢动物传播病毒的流行病学研究中，需要考虑环境温度的作用。
Studies were conducted to determine the effect of environmental temperature on the susceptibility of Culex pipiens (L.) to Rift Valley fever (RVF) virus. Larval rearing temperature (13, 17, 19, or 26 degrees C) did not affect the susceptibility of adult female Cr. pipiens to infection with RVF virus. In contrast, the adult holding temperature after a viremic blood meal affected infection rates in females. Significantly fewer mosquitoes contained detectable virus when they were held at cooler temperatures, 13 degrees C (10%), 17 degrees C (20%), and 19 degrees C (41%) than at a warmer temperature, 28 degrees C (91%). For mosquitoes held at 13 degrees C and then switched to 26 degrees C, infection rates increased steadily with increased time at 26 degrees C. There was no effect on the ability to detect RVF virus in adult females that were subjected to cooler holding temperature (17 degrees C) after they were first held at warmer temperature (26 degrees C). The role of environmental temperature needs to be considered in studies on the epidemiology of arthropod-borne viruses.
