Abstract: Objectives: We investigated the presence of subtropical mosquito vectors that may become established in the Republic of Korea (ROK) owing to climate change. Comprehensive surveillance was conducted on Jeju Island, a region with a subtropical climate with active external entry routes, where the risk of subtropical mosquito introduction and establishment is increasing. Methods: complex, were subjected to genetic analyses for species identification. The collected specimens were screened for major mosquito-borne viruses, including the Japanese encephalitis, West Nile, Zika, Dengue, Chikungunya, and Yellow fever viruses. Results: individuals were identified from five collection sites. Furthermore, all specimens tested negative for six major mosquito-borne viruses. Conclusions: This study provides the first official report confirming the presence of subtropical mosquitoes on Jeju Island, ROK. These findings highlight the need to strengthen vector surveillance systems and refine public health strategies to address the potential establishment and northward expansion of subtropical mosquito species due to ongoing climate change and reveal an increased risk of exotic species introduction.
