What is it?
The Asian longhorned beetle (ALB) is an exotic invasive wood boring beetle that infests and kills healthy trees, including ash, birch, elm, maple, poplar and willow.
How will it impact Oregon?
ALBs are tree-killing pests. Their larvae feed on wood tissue beneath the bark. ALB poses a serious threat to our urban and natural forests if introduced to the Pacific Northwest.
What does it look like?
Where is it?
The first established population was detected in 1996 in New York. ALB has since spread to several more states.
Where did it come from?
The Asian longhorned beetle is native to Northeastern Asia. It was accidentally transported to the US in solid wood packing material.
What should you do?
Early detection is our best defense. Report a suspected ALB sighting to the OSU Plant Clinic. The OSU Insect ID Clinic also provides free insect identification. You can help prevent ALB transport by using local firewood.
