      An invaded long-horned beetle was first discovered attacking ornamental trees in New York City and Chicago, followed by appearances most states in the northeastern portion of the United States as well as in California beginning in 1996.  Entry into North America may have occurred in wooden packing crates originating in China.  The Asian Long-Horned Beetle is native to Asia, where it kills many species of trees, including poplars, maples, elms and mulberries.  These insects are large and may be easily recognized by their large antennae and horns.

 

       Oviposition cavities created by females in tree trunk bark and branch axils, or right on the trunk.  Mature larvae enter the heartwood of the tree, destroying the quality of the wood.  Higher populations of beetle larvae can kill trees by girdling.  Adult beetles emerge in the summer through holes in the bark.  Sap flows heavily from larger wounds and infested trees are prone to secondary attack by diseases and other insects.  This beetle adversely affects the human environment by killing valuable shade trees, as well as injuring or even killing forest trees of economic value such as the sugar maples in the north and Canada.   Structural weakening of trees by tunneling larvae also poses a physical danger to pedestrians and vehicles by falling limbs or entire trees during storms.

 

       The primary damage has been on street trees in infected sites.  These trees require removal, treatment to destroy all life stages present and replacement. In the forest ecosystem, the economic impact could be far greater than eradication and containment costs and could adversely impact export markets for various hardwood products such as veneers.

 

       This beetle is widely distributed in China, Japan and Korea where it causes severe damage from 21-43½ north latitude and 100-127½ east longitude, especially in wooded aeas.  In the United States the beetle is a problem in New York, New Jersey, and Illinois.  In Canada the beetle attacks trees in Toronto and Ontario.  However, it has been intercepted widely at warehouse and ports all over the United States.
