Hot Topic: Asian Longhorned Beetle

The Asian longhorned beetle (Anoplophora glabripennis) is a large (1 - 1.5 inches long) black beetle with white spots that is native to Asia.  It was discovered in the United States in 1996 in Long Island, New York with subsequent infestations in Chicago, other locations in New York, Massachusetts, and New Jersey.  Eradication efforts have been successful in some of these locations.  Unfortunately for Kentuckians, the beetle was most recently detected in southeastern Ohio in June 2011.

Unlike the emerald ash borer, which attacks only ash trees, this beetle will attack a wide variety of hardwood trees including maple, boxelder, birch, horse chestnut, poplar, willow, elm, hackberry, sycamore, mimosa, and ash.  The beetle larvae bore deep into the trees and will eventually kill them.
