Abstract
To investigate mosquito species composition and mosquito-borne pathogens in airport and seaport quarantine areas in the Chungcheong region to support the prevention of imported vectors and mosquito-borne diseases. Mosquitoes were collected twice monthly from March to November 2025 at nine sites in Gunsan Port, Pyeongtaek-Dangjin Port, Daesan Port, and Cheongju International Airport, using black light, Biogents-sentinel, and gravid traps, except once in March and November. Collected mosquitoes were identified and subsequently tested for flaviviruses and chikungunya virus using nucleic acid detection assays. A total of 8,393 mosquitoes representing nine species were collected. Culex pipiens predominated (67.3%), followed by Aedes albopictus (16.9%), Aedes vexans (4.0%), Anopheles spp. (3.4%), and Ochlerotatus koreicus (2.8%). Mosquito abundance peaked in July, with Gunsan Port accounting for 58.8% of all collections. All mosquito pools tested negative for flavivirus and chikungunya virus. No exotic mosquito species, including Aedes aegypti, or mosquito-borne pathogens were detected in the quarantine zones. However, Cx. pipiens, a potential vector of West Nile virus, and Ae. albopictus, a potential vector of dengue, Zika, and chikungunya viruses, increased by 152.7% and 52.3%, respectively, compared with the previous year (2,235 and 929, respectively). Continued mosquito vector surveillance in quarantine areas can provide baseline data to support for early detection of introduced mosquito-borne disease risks and inform effective quarantine and vector control strategies.
