Sugar maple is one of the favorite tree species of quarantine pest Hyphantria cunea. Because pests like to eat it, sugar maple has also become a prohibited species. If it is planted or imported, it will be sentenced. Strengthening quarantine is to prevent the long-distance migration of the American white moth.

Hyphantria cunea mainly feeds on the leaves of plants by larvae, which takes a large amount of food. When the damage is serious, it can eat all the leaves of host plants and chew the bark, thus weakening the ability of trees to resist harm and stress.

Hyphantria cunea will invade farmland, harm crops, reduce production and harvest, or even stop production. Larvae and adults can easily spread over long distances with human activities, materials and means of transportation.

Hyphantria cunea has strong adaptability to harsh environment, and is resistant to cold, high temperature and hunger. A female moth lays an average of 3-6 eggs at a time, up to 19. If it is not prevented, its offspring will reach at least several hundred thousand after one year.
