Asian longhorn beetle (ALB), a native of China and Korea, was first discovered in the U.S. on Long Island in New York in 1996. ALB is found in deciduous hardwood trees (e.g., maple, sycamore, willow, boxelder, birch, elm, ash). It has spread to Illinois, New Jersey, and Massachusetts, but has been eradicated in Illinois. ALB has also been detected in or near warehouses in parts of California and Washington where it is believed to have been transported in shipping materials such as wooden boxes and pallets. ALB is considered to be a serious threat to U.S. trees and has been particularly devastating to urban and suburban landscapes.

Asian longhorn beetles are large (1-1.5 inches long), shiny black, and bullet shaped. Damage is caused by the larval or immature stage. Management efforts have focused on quarantines, removal of infested trees, injection of soil and trees with insecticides, and surveillance.
