摘要: To identify the mosquito species competent for West Nile virus (WNV) transmission, we evaluated 10 California that are known vectors of other arboviruses or major pests: Culex tarsalis, Cx. pipiens pipiens, p. quinquefasciatus, stigmatosoma, erythrothorax, Ochlerotatus dorsalis, Oc. melanimon, sierrensis, Aedes vexans, and Culiseta inornata. All became infected were able to transmit WNV at some level. Ochlerotatus, Culiseta, low moderately efficient vectors. They feed primarily on mammals could play a secondary role in transmission. pest species, quinquefasciatus from southern least laboratory populations complex most likely primary enzootic maintenance transmission California.
