West Nile Virus (WNV) is transmitted by infected mosquitoes. Vector mosquitoes usually acquire these pathogens from feeding on an infected host, and transmit the pathogens to a naive host during feeding events. To understand the virus transmission dynamics and to survey WNV throughout country, the present study has been conducted. We collected mosquitoes in Jeju, Busan, Gunsan, and Incheon using CDC light trap and BG Sentinel trap from April to October in 2016. Among collected mosquitoes, blood-fed mosquitoes were conducted blood meal identification assay and the other mosquitoes were subjected to virus detection using real-time PCR method. A total of 29,603 mosquitoes representing 8 genera and 19 species were collected. The most dominant species was Culex pippins complex (35.0%) followed by Cx. bitaeniorhynchus (12.2%), Armigeres subalbatus (11.2%), Aedes albopictus (10.8%), Ae. vexans nipponii (10.3%), and Ochlerotatus dorsalis (8.4%). The blood meal source were of mammal (70.4%), birds (29.0%) and amphibian (0.6%). WNV was not detected in any mosquitoes.
