Beetles kill hardwood trees

Asian Longhorn BeetleIn recent years, the Asian longhorned beetle (Anoplophora glabripennis) and other wood-boring beetles have been entering North America in solid wood packing material from Asia. Some of these insects have the potential to become very serious pests of North American forests.

Isolated infestations of the Asian longhorned beetle (ALB) have been discovered in Chicago and New York. In China, this insect is a serious pest that kills hardwood trees. Tunneling by beetle larvae girdles tree stems and branches. Repeated attacks lead to dieback of the tree crown and eventual tree death.

Tree hosts:

In the United States, the ALB prefers maple species (Acer spp.), including boxelder, Norway, red, silver, sugar and sycamore maples. Other known hosts are horsechestnut, black locust, elms, birches, willows, poplars, and green ash.
