Asian Longhorned Beetle
The Asian longhorned beetle, Anoplophora glabripennis, infestations across the U.S. cause huge economic losses for the nursery and forest industries. Municipalities and homeowners with infested trees may incur major damage as many hosts for ALB are commonly found in urban and suburban areas. Falling trees and branches are a safety hazard as ALB weakens tree structure as the larvae chew large tunnels in the wood. Trees eventually die from this damage.
Know the signs:
Large round exit holes are large enough to fit a pencil.
Sap oozing down bark.
Shallow, discolored depressions where females lay eggs.
Sawdust and/or wood shavings pushed out by larval feeding.
ALB has killed thousands of trees in 5 states and threatens trees in every state. Once a beetle infests a tree, there is no cure. Our best line of defense against this devastating pest is vigilance. South Carolinians can look at trees in their landscape for signs and symptoms of ALB.
If you suspect you have found an Asian longhorned beetle or an infested tree please report it using the Asian Longhorned Beetle Reporting Tool.
