The ecology of western equine encephalomyelitis virus (WEE) was studies during 1994-1996 along a portion of the north shore of the Salton Sea in Coachella Valley, California, known to support a focal Aedes dorsalis (Meigen) population. WEE was detected during 1995 by the seroconversion of sentinel chickens concurrently at sites within and outside of the area supporting Ae. dorsalis. WEE was not detected during 1994 or 1996; neither was WEE detected by seroconversion of sentinel rabbits nor by isolation from host-seeking females of either the primary vector, Culex tarsalis Coquillett (42,083 females tested in 913 pools), or Ae. dorsalis (10,804 females tested in 245 pools and 1,940 adults reared from field-collected immatures tested in 72 pools). Collectively, the results of this and previous investigations indicate that Ae. dorsalis may not be essential for the maintenance or amplification of WEE virus in southeastern California.
1994年至1996年期间，在加利福尼亚州科切拉谷索尔顿海北岸的一部分地区对西部马脑炎病毒（WEE）的生态学进行了研究，该地区已知有一群集中的背点伊蚊（Meigen）。1995年，在支持背点伊蚊的区域内外的地点，通过哨兵鸡的血清转化检测到了WEE。1994年或1996年未检测到WEE；通过哨兵兔的血清转化或从主要传播媒介尖音库蚊（Coquillett）（在913个样本中检测了42,083只雌蚊）或背点伊蚊（在245个样本中检测了10,804只雌蚊，从野外采集的未成熟个体饲养的1,940只成虫在72个样本中检测）的宿主寻找雌蚊中分离均未检测到WEE。总体而言，本次及先前调查的结果表明，背点伊蚊对于加利福尼亚州东南部WEE病毒的维持或扩增可能并非必不可少。
