Abstract

Aedes albopictus, a common species in the Republic of Korea, is internationally known as a major vector for various diseases, and it is well-adapted to urban environments. Recent insect outbreaks in urban areas, attributed to climate change and urban heat islands, have increased the necessity of researching the effects on mosquito populations. This study analyzed climate data from 25 Automatic Weather System (AWS) stations in Seoul, identifying urban areas with pronounced heat island effects and suburban areas with milder effects. Nine urban heat island conditions were established based on this analysis, under which the hatching rates of Ae. albopictus were examined. The results revealed an increase in hatching rates correlating with the intensity of the urban heat island effect. Regression analysis further indicated that this trend accelerates as the strength of the heat island effect increases. This study suggests that temperature variations resulting from urban heat island phenomena can significantly influence the hatching rates of Ae. albopictus.

한국에서 흰줄숲모기(Aedes albopictus)는 일반적으로 매우 흔한 종으로 여기지지만, 해외에서는 주요 질병 매개체로 인식되고 있으며, 도시 환경에 잘 적응하는 특징을 가지고 있다. 최근 도심 지역의 기후변화와 열섬 현상에 따른 곤충의 대발생이 보고되면서, 이러한 환경 변화가 모기의 부화율에 미치는 영향에 대한 연구의 필요성이 증가하고 있다. 본 연구를 위해 서울시 내 25개의 기상청 자동관측장비(AWS)에서 수집된 기후 데이터를 분석하여, 열섬 현상이 강한 도심 지역과 열섬 현상이 약한 교외 지역을 선정하였으며, 이를 통해 임의의 사이구간을 생성하여 총 9개의 열섬 조건에서 흰줄숲모기의 부화율을 분석하였다. 분석 결과, 열섬 현상이 강할수록 부화율이 증가하였으며, 회귀분석을 통해 열섬 강도가 높아질수록 이러한 추세가 더욱 빨라질 수 있음을 확인하였다. 이러한 연구 결과는 도시열섬 현상에 따른 기온 변화가 흰줄숲모기의 부화율에 중요한 영향을 미칠 수 있음을 시사한다.
