Emerald Ash Borer Damage

Back for more info on EAB? This photo was taken in October 2010 on Morgan Road in Chili, NY, following the discovery of several infested trees. Experts have determined that EAB has been in this tree for approximately 5 years. This is significant in that nearby ash trees, while not showing signs or symptoms, are almost certainly already infested.
Pictured here are the ‘serpentine galleries’ created by the feeding of the Emerald Ash Borer larvae. The larvae travel back and forth, feeding on the cambium of the tree, just beneath the bark. The cambium is where the vascular system of the tree is located. When this tissue is destroyed, the tree cannot transport water and nutrients and the end result is death.
