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.

As a part of disease vector and possible overseas inflow caused by global warming monitoring around airport and port area, the distribution of domestic mosquitoes was investigated using BG-sentinel trap. Mosquitoes were collected during 5-days per each area in early September, using 10 traps in Cheongju (airport) and 15 traps in Pyeongtaek (port). The numbers of mosquitoes collected in Cheongju and Pyeongtaek area were 1,762 including 10 species and 1,042 including 11 species respectively. In Cheongju, Aedes albopictus (657 individuals, 37.3%) and Culex pipiens complex (415 individuals, 23.6%) were dominant species; while in Pyeongtaek, Cx. pipiens complex (806 individuals, 77.4%) was dominant followed by Anopheles spp. (90 individuals, 8.6%) and Ochlerotatus koreicus (79 individuals, 7.6%). Similar species were collected in both Choengju and Pyeongtaek area. Although most species collected in both Cheongju and Pyeongtaek area were the same, Cx. inatomii was only collected in Pyeongtaek. In case of the Genus Aedes, more number of Ae. albopictus was collected compared to Oc. koreicus in Cheongju; while Oc. koreicus was more in Pyeongtaek. In case of the genus Culex, the individuals belonging to the vishinui group were collected such as Cx. bitaeniorhynchus, Cx. tritaeniorhynchus and Cx. orientalis. This study may provide basic information for efficient prevention of vector mosquito and potential overseas inflow of diseases, also we would try to expand different area in Korea.
