Asian Long-horned BeetleHARRISBURG – The Pennsylvania Department of Agriculture (PDA) and the Penn State College of Agricultural Sciences (PSCAS) are asking for the public and professionals in the green industry to keep on the lookout for the Asian long-horned beetle (ALB) (Anoplophora glabripennis).

The ALB was introduced into his country more than two decades ago in pallet and container wood from Asia. The beetle is a killer of trees, especially hardwoods, like maple. Once infested, a tree will die in a couple of years.

USDA estimates that if the beetle spreads across the United States, 1.2 billion trees could die. The beetle could devastate the northeastern hardwood forests, like those found in Pennsylvania.

So far, the beetle has been discovered infesting trees in New York, New Jersey, Massachusetts, Ohio and Illinois. The USDA takes immediate action to eradicate the beetle wherever it is discovered. It has not yet been discovered in Pennsylvania.

The beetle is about 1 to 1½ inches long, with long black and white striped antennae. If you think you have seen an Asian long-horned beetle, call the Pennsylvania Department of Agriculture’s toll-free pest hotline at 1-866-253-7189 or e-mail You can also call your local Penn State Extension Office. If you can capture a specimen for identification, that is even better.
