What is the emerald ash borer?

Emerald ash borer (EAB), Agrilus planipennis, is an exotic, invasive beetle that belongs to the metallic wood-borer family (Buprestidae).  It infests and destroys native North American ash trees.  Ash trees infested with the Emerald Ash Borer will typically die within three to five years. EAB adults are dark metallic green, a half-inch long and one-sixteenth of an inch wide. 

The adult beetle deposits eggs on the bark surface or in bark crevices on the trunk or branches of ash trees.  The eggs hatch, and the larvae chew through the bark and into the cambial region.  As they continue to feed underneath the bark, they make galleries that wind back and forth in a serpentine pattern.  The insect overwinters as a larva, and in the spring, will emerge as an adult through a D-shaped exit hole.  The larvae feed on the inner bark layer, disrupting the flow of nutrients and eventually killing the tree. 

Emerald Ash Borer in the City of Oregon

The Emerald Ash Borer has been identified in the City of Oregon.  The City of Oregon is removing and replacing ash trees located in the City right of way (the area between the sidewalk and street) that have been infested by the Emerald Ash Borer.  In the removal process, the City will grind out the stumps and re-landscape.
