The Jeonnam Forestry Research Institute is in the midst of research on controlling the pine defoliator moth that damages pine trees.

The maple hornworm larvae, approximately 15mm in length, eat maple tree leaves and flower buds from July to October. This causes the leaves to turn brown and the flowers to fail to bloom properly, resulting in significant landscape damage. In particular, the powder from the cocoons built during the pupal stage can cause allergic dermatitis if it comes into contact with the skin.
