Abstract

The aim of this study was to determine the presence of West Nile Virus (WNV) in mosquitoes in northeastern Venezuela. Research was conducted in the Laguna de los Patos, Cumana, Sucre State to demonstrate the presence of WNV RNA in mosquitoes caught in traps of Light (CDC + CO2) by RT-PCR, during the period July 2007 to February 2008. We found a positive mosquito pool for the species Coquillettidia (Rhynchotaenia) venezuelensis (Theobald, 1912). The minimum rate of infection of the caught was 0.16/ 1,000 individuals. Continued entomological surveillance is needed for establishing with conclusive criteria etiological responsibility of this and other species in these arboviruses.
