1991-1994年夏季，在帝国谷地，通过从主要媒介库蚊中分离到西方马脑脊髓炎(WEE)和圣路易斯脑炎(SLE)病毒，并通过哨兵鸡的血清转换试验，检测到了这两种病毒。地方性传播每年都不会首先在特定地貌特征附近的采样点发现，例如沿新河的苍鹭栖息地和其他河岸栖息地，沿墨西哥边境的地点，或索尔顿海南岸的盐沼和淡水沼泽。尽管冬季气温温和，春季Cx丰度较高。直到6月或7月才检测到鞑靼、WEE和SLE的活性，这表明在通过检测蚊子池病毒感染或哨兵鸡血清抗体进行检测之前，可能有必要进行相当大的放大。结果不允许对早期季节控制努力或对病毒季节间持续机制的研究进行空间聚焦。
Western equine encephalomyelitis (WEE) and St. Louis encephalitis (SLE) viruses were detected in the Imperial Valley during the summers of 1991–1994 by isolation from the primary vector,Culex tarsalisCoquillett, and by the seroconversion of sentinel chickens. Enzootic transmission consistently was not detected first each year at sampling sites near specific landscape features such as a heron rookery and other riparian habitats along the New River, sites along the Mexican border, or saline and freshwater marshes along the southern shore of the Salton Sea. Despite mild winter temperatures and the elevated vernal abundance ofCx. tarsalis,WEE and SLE activity was not detected until June or July, indicating considerable amplification may be necessary before detection by testing mosquito pools for virus infection or sentinel chicken sera for antibodies. Results did not permit the spatial focusing of early season control efforts or research on mechanisms of virus interseasonal persistence.
