A second infestation, the only other known infestation of this insect in the United States, exists in a small area of Amityville, Nassau-Suffolk Counties of New York. This infestation was traced to a tree service company that had cut and removed trees from Brooklyn. The ALHB can attack and eventually kill healthy mature hardwoods during its larval feeding in the heartwood, which inhibit the tree's vascular system.
Infested trees are also prone to secondary attack by other diseases and insects.
But, ALHB is also known to infest populars, willows, elms, mulberries, and black locusts in its native distribution of China, Japan, and Korea. State and federal quarantines are currently preventing the movement of infested tree materials to uninfested areas. Within the known infested areas, state and federal officials are conducting an aggressive eradication program consisting of tree removal of infested trees. In addition, an extensive field survey was continued in 1997 to locate any new infestations and determine the extent of suitable host materials in the surrounding states. This survey information can help assess the risks of this potent ially devastating exotic pest to U.S. agriculture including major industries like the sugar maple and timber industries, to name a few.
