Asian Longhorned Beetle

ALBsymptomsThe Asian Longhorned beetle is an invasive, wood boring insect from China which was accidentally introduced to the U.S. via packing materials. ALB is a member of the Cerambycid family. The adults are large, black beetles, approximately 1 – 1 1/2 inches long with irregular white spotting on their wing covers and very long, black and white striped antennae. Onthe male, the length of the antennae can be up to twice the length of their body. The larva is cream colored, grub-like, approximately 1-2 inches long when mature. This horned beetle has been identified in NY, NJ, IL, MA, and recently OH.

Symptoms

Symptoms of ALB infestation are similar to symptoms of many pest infestations, including yellowing leaves, and dieback of branches. Specific signs include bleeding wounds in the trunk or large limb bark, indicating oviposition of eggs. There may also be large (3/8 inch) sized, perfectly circular holes in the trunk or large limbs and frass (sawdust) on the ground near the holes. The beetles themselves may also be visible during mid to late summer months, feeding in the canopy.
