Emerald Ash Borer found in the Triangle, Wake Co. under quarantine

RALEIGH – Evidence of EAB was found by the N.C. Department of Agriculture and Consumer Services staff in woods near the Raleigh-Durham International Airport.
“This brings the total counties in the state under EAB quarantine rules to seven, with detections in Granville, Person, Vance and Warren counties in 2013 and Wayne County earlier this year,” Troxler said. “We continue to monitor other counties for this highly destructive pest by trapping areas with ash trees. If you see the purple, triangle-shaped traps, please do not disturb them.”
The beetle was first detected in the United States in Michigan in 2002. It is responsible for the death or decline of tens of millions of ash trees across the country.
Under the state quarantine, all hardwood firewood and plants and plant parts of the ash tree -- including living, dead, cut or fallen, green lumber, stumps, roots, branches and composted and uncomposted chips -- cannot be moved outside the county.

The Plant Industry Division and the N.C. Forest Service are working in cooperation with the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service.
Symptoms of emerald ash borer in ash trees include a general decline in the appearance of the tree, such as thinning from the top down and loss of leaves. Clumps of shoots, also known as epicormic sprouts, emerging from the trunk of the tree and increased woodpecker activity are other symptoms. The emerald ash borer is not the only pest that can cause these.
Emerald ash borers overwinter as larvae. The adult beetle is one-fourth to a half-inch long and is slender and metallic green. When the adults emerge from a tree, they leave behind a D-shaped exit hole. The larvae can also create serpentine tunneling marks, known as feeding galleries, which are found under the bark of the infested trees.
