Asian Longhorned Beetle

The Asian longhorned beetle (ALB) is an invasive wood-boring insect that attacks hardwood trees, including maple, birch and elm. A large infestation of ALB was discovered in Worcester, MA in August 2008 and is currently under eradication. A small infestation of just 6 trees was found in Boston in 2010.

The spread of ALB would cause negative impacts to the maple sugaring, nursery, tourism and forest product industries of Massachusetts, and would seriously threaten our state's forest, park and street trees. The Division of Crop and Pest Services, through the Cooperative Agricultural Pest Survey (CAPS) Program, provides public outreach and screening of potential Asian longhorned beetle sightings in order to prevent the further spread of this invasive pest. If you would like to schedule a free presentation or training session, or order free ALB outreach materials, use the contact information at the top of this page.
