We performed a survey for flavivirus infection and distribution of Aedes albopictus that known as Zika and Dengue virus vector using black–light trap and BG-sentinel trap around urban area in Korea. Mosquitoes were collected in 27 cities during March to November (twice a month) year 2016. Total numbers of mosquitoes collected 102,102 including 19 species 8 genera during collecting period. Total 21,467 Ae. albopictus was collected that 20,961(24.3%) by BG-sentinel trap and 506 (3.2%) by Black-light trap in urban area. Trap index(trap/night) of Ae. albopictus was showed highest in Hamyang (TI:992.3) and lowest in Taebaek (TI:0.3) there was only collected by Black-light trap. A total of 894 pools from all collecting Ae. albopictus were performed a Flavivirus detection. Flavivirus was not detected during study period. This study may provide basic information for surveillance of imported diseases (include Zika virus) and vectors in Korea.

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.
