RESUMEN
Experiments were conducted in the laboratory on C. bitaeniorhynchus to determine the possible role of males in maintaining or sustaining the Japanese encephalitis virus activity in nature. It was found that infected males are capable of passing on the virus to female mosquitoes while mating. The occurrence of phenomenon of venereal transmission of this virus may have epidemiological importance.

A strain of Japanese encephalitis (JE) virus has been isolated from a pool of female mosquitoes of C. tritaeniorhynchus, using C. bitaeniorhynchus cell line. This is the first report of JE virus isolation from mosquitoes in Gorakhpur district of Uttar Pradesh, north India.

Studies on the transovarial transmission of Japanese encephalitis virus (JEV) by orally infected female C. pseudovishnui showed that these mosquitoes were capable of transmitting JEV by bite to susceptible hosts. Infected females also transmitted the virus vertically to its first generation progeny. In another experiment, C. tritaeniorhynchus was also shown capable of transmitting the virus vertically to its first generation progeny. However, there was no apparent difference in transovarial transmission capabilities of these two species in orally infected mosquitoes.
