In 2022, the non-native longhorn beetle Anoplophora horsfieldii (Hope) was officially reported on Jeju Island, Korea, marking its first confirmed occurrence outside native range. This insect damages living hackberry trees, a common species in posing significant threat to tree health due high population levels Island. study aimed estimate climatic suitability and spread potential of A. support effective management regions, particularly We adopted distribution modeling (SDM) approach using global presence records bioclimatic variables requirements. Random forest (RF) gradient boosting machine (GBM) algorithms were used construct niche models, their outputs combined into an ensemble prediction identify regions with suitability. Potential habitats further delineated by integrating map vegetation data from Using this habitat map, we simulated incorporating demographic processes various dispersal parameters. Our findings indicate that could potentially across parts Southeast East Asia, including southern Korea Japan. On extensive suitable areas identified through host analysis, suggesting establish island except high-altitude Mt. Halla. The analysis highlights urgent need for prompt actions control expanding Island calls ecological studies invader. Despite uncertainties arising limited information, necessity implementing domestic quarantine measures strategies while considering multiple scenarios behavior insect.
