The Jeonnam Forestry Research Institute (Director O Deok-shil) is focusing its efforts on researching the occurrence patterns and control technologies of the pine processionary moth, which causes significant damage to street trees and park trees in living areas and can also cause allergic skin symptoms in people. The caterpillars of the pine processionary moth are about 15mm in length and eat pine tree leaves and flower buds from July to October. This results in significant landscape damage, such as leaves turning brown and flowers not blooming properly. In particular, the powder produced when the caterpillars build their cocoons can cause allergic dermatitis if it comes into contact with the skin. Even after the cocoon period ends, the powder remains on the trees and can affect the human body.
