Emerald Ash Borer- be on the watch

The Emerald ash borer is currently NOT found in Texas.  It has recently been reported in Nebraska and Colorado, so Texans should be looking for it.  If you suspect that you have these insects, collect samples of the insects and submit them to me or your local Extension Entomologist.

Emerald ash borers are small (less than the diameter of a penny), elongated, metallic green beetles. Antennal segments 1-3 are cylindrical while segments 4-11 are serrate (triangular or saw-like). These beetles ONLY attack ash trees and can kill a tree within 3-5 years.

Emerald ash borers were accidentally introduced into the United States in the 1990's, but wasn't discovered to be the source of ash tree death until 2002.  They can be easily moved in ash logs and firewood.  There are more tips on how to identify here.

You can find signs and symptoms of infestation here.
