We conducted a investigation for distribution and flavivirus infection of mosquitoes using black –light trap around Incheon international airport there was possible overseas inflow caused by global warming in Korea. Mosquitoes were collected once a week April to October during 6 years (2009~2015). The numbers of mosquitoes collected in Oseong and Eurwang mountain were 8,969 and 7,978 including 12 species 7 genera respectively during collecting period. Culex pipiens complex was dominant species in two collecting area as 4,621(51.5%) in Oseong and 3,761(47.1%) in Eurwang mountain. A total of 16 pools from 88 Aedes albopictus were performed a Dengue virus (DENV) detection and total 628 pools from 11,146 other mosquitoes performed a West nile virus (WNV) detection. Flavivirus was not detected during study period. This study may provide basic information for surveillance of imported diseases and vectors in Korea.
