Red imported fire ant (Solenopsis invicta) is a notorious pest which has caused damage of human life. Recent expansion of its habitat due to climate change has threatened where it cannot live before. South Korea has been exposed to its invasion, alerting early assessment of potential distribution of Solenopsis invicta. The objective is, hence, to predict potential distribution of Solenopsis invicta in South Korea based on climatic suitability. CLIMEX software was used for predicting Solenopsis invicta distribution in 2020 under RCP 8.5 climatic change scenario. Result showed that climates in coastal areas, Daegu, and Jeju island would be suitable for inhabitation of Solenopsis invicta. This results suggested that the risk of Solenopsis invicta invasion might be increased with the current climate change.
