Dengue is the most important arboviral disease in tropical and subtropical areas where 2.5 billion people are at risk of infection. Aedes albopictus will be a major vector transmitting dengue virus in Korea, where this virus overseas inflow is possible. We collected mosquitoes in Jeju, Busan, Gunsan, and Incheon using BG sentinel trap from April to October in 2016. Collected mosquitoes were conducted virus detection using real-time PCR method and analysis bloodmeal source of Ae. albopictus. A total of 15 species comprising 7 genera were identified and 4,854 female mosquitoes collected. The most dominant species ratio (SR) was 52.9% (Culex pippins complex) followed by 20.3% (Ae. albopictus), 10.8% (Ae. vexans nipponi) and Ochlerotatus dorsalis (3.8%). Dengue virus was not detected. Bloodmeal source of Ae. albopictus was mammals (80.9%) followed by birds (18.6) and amphibians (0.5).
