The Asian longhorned beetle (ALB), Anoplophora glabripennis, is a woodboring beetle native to China. ALB develops and reproduces within healthy and stressed deciduous hardwood trees, such as maple, birch, horse chestnut, poplar, willow, elm, and ash. The attacked tree will eventually die.

The ALB hitchhiked to the United States in solid wood packing material used to import goods from Asian countries. ALB also can spread with firewood movement. There are currently ALB infestations being eradicated from Massachusetts, New York, and Ohio. ALB has been successfully eradicated out of Illinois, New Jersey, and Toronto, Canada.

The Asian longhorned beetle has not been found in Maine.
