Abstract: Japanese encephalitis virus (JEV) is transmitted by Culex vishnui subgroup, primarily Culex tritaeniorhynchus Giles, and amplified by infection of pigs / Ardeidae birds in nature. A longitudinal study of vector abundance and infection frequency of JE vectors was conducted from 2011-2013 in 4 villages namely Senthimangalam, Ariyanayagipuram, Kuthalaperi and Magiladi of Tirunelveli district. A total of 13, 343 adult mosquitoes were collected and processed by antigen capture ELISA. JEV was detected from ten species of mosquitoes – 28 positive pools, viz. Cx. tritaeniorhynchus (10), An. subpictus (7), Cx. infula (2), Ma. annulifera (2), Ma. uniformis. (2), Cx. bitaeniorhynchus (1), Cx. quinquefasciatus (1), An. pallidus (1) An. barbirostris (1) and Ar. subalbatus (1). Vector incrimination with JEV indicating a possible public health threat in the near future and helps programme people to develop appropriate control strategies.
