Culex vishnui
Culex vishnui is a mosquito belonging to the Culicidae family. It is the most common vector of the Japanese encephalitis virus in India, Sri Lanka, Thailand, and Sarawak.
Identification
The Culex vishnui Theobald mosquito species belongs to a sub-type that also includes two other carriers of the Japanese encephalitis virus - Culex tritaeniorhynchus Giles and Culex pseudovishnui Colless. Since the females of these different species are difficult to morphologically distinguish from one another, an rDNA based diagnostic PCR is used for identification.Morphological identification of multiple JEV carrier mosquitoes including Cx. vishnui are based on identifying specific features of the legs, abdomen, palpi, wings, proboscises, and tarsi. The identification of Cx. vishnui is confirmed by verifying that the "anterior surface of hindfemur with pale stripe does not contrast with dark scaled area".
