Ohio State University Extension Educator Dr. Curtis Young said the Asian Longhorn beetle is a borer and is as even greater concern then the Emerald Ash Borer.
Fading Forests III is a new report released by the University of Tennessee and The Nature Conservancy compiling the latest data and analysis on the introduction, spread, and costs of non-native invasive tree pests and diseases.

In the last dozen years the emerald ash borer has spread from three states to 22; the Asian longhorned beetle has been detected at four additional sites; 28 new tree-killing pest species have been discovered.
