Development of a species-diagnostic polymerase chain reaction assay for the identification of Culex vectors of St. Louis encephalitis virus based on interspecies sequence variation in ribosomal DNA spacers.

Abstract excerpt

Culex pipiens complex mosquitoes (Cx. p. pipiens and Cx. p. quinquefasciatus) are among the principal vectors of St. Louis encephalitis (SLE) virus in the eastern United States; Cx. restuans and Cx. salinarius play secondary roles in the transmission and maintenance of the virus cycle. Accurate identification of these three species in field collections is required for epidemiologic studies of SLE virus...
