West Nile Fever is one of most serious disease spreading throughout world since 1990. West Nile Virus (WNV) is transmitted by infected mosquitoes. The possibility of overseas inflow of this virus seems to be high in Korea. To know the WNV infection of mosquitoes, we collected mosquitoes in Jeju, Busan, Gunsan, and Incheon using CDC light trap and BG Sentinel trap from April to August in 2016. Collected mosquitoes were conducted virus detection using real-time PCR method. A total of 22,632 mosquitoes representing 9 genera and 18 species were collected. The most dominant species was Culex pippins complex (36%) followed by Aedes vexans (13%), Ae. albopictus (10%) and Ochlerotatus koreicus (10%). WNV was not detected in any mosquitoes until now.
