Following the increase of vector-borne infectious diseases due to climate change and international exchange, the study collected mosquitoes using BL and BG twice a month for nine months, from March to November 2019, at cattle sheds, habitats for migratory birds, and city centers, after which they were classified, identified, and checked for the presence of flavivirus by using real time RT-PCR in order to classify and identify the species of disease vector mosquitoes in the Jeonbuk, estimate their population, and investigate their regional distribution and the presence of viral pathogen infection. A total of 8,234 mosquitoes were collected, which were categorized as seven genera and twelve species. In terms of environment types, the highest number of mosquitoes ? 3,884 (Trap Index 215.8) ? were collected at the Wanju cattle shed. In terms of mosquito populations, Anopheles spp. was the dominant species with 2,538 mosquitoes (30.9%) collected. As the dominant species, Anopheles spp. mosquitoes were first collected in April, and the greatest numbers were collected in the order of July, August, and June, with numbers gradually decreasing starting in August. In terms of the mosquito species collected in each environment, Anopheles spp. mosquitoes were collected in cattle sheds, Aedes vexans mosquitoes were collected in habitats for migratory birds, and Culex pipiens pallens mosquitoes were collected in city centers, revealing a difference in the species of mosquitoes collected depending on the environmental characteristics. The collected mosquitoes were tested for flavivirus using real time RT-PCR, but all tests turned out negative. The results of the collection confirmed the habitation of mosquitoes related to vector-borne diseases, predicting further results if an abnormal climate further progresses. The study is also expected to be used as comprehensive pest control standards for future mosquitoes.
