Emerald Ash Borer Detected in North Carolina
The emerald ash borer (EAB), a destructive exotic insect pest, has now been detected in North Carolina. These beetles feed under the bark of ash trees (Fraxinus spp.), eventually killing them. The detection is not unexpected, as EAB was already present in Virginia and Tennessee. In North Carolina, Person, Granville, and Vance counties are under quarantine. No movement of ash trees or ash wood products, or of hardwood firewood, is allowed from these counties. The reason is that EAB can be present inside these materials and inadvertently moved long distances by people.
For more, including contact information if you suspect you have found this pest, see the North Carolina Department Agriculture & Consumer Services Press Release 17-Jun-2013 (http://www.ncagr.gov/
Further information is found on the North Carolina Forest Service Emerald Ash Borer FAQ page (http://www.ncforestservice.
Note: At the time of this writing, that FAQ page still had not been updated to reflect the fact that this is now in North Carolina.

Emerald Ash Borer
Since emerald ash borer (EAB) arrived in Michigan in 2002 a lot of great research has been done to understand how to manage trees with EAB present. This work has also resulted in Extension publications that will help us deal with EAB here in North Carolina. I will link to these important publications and develop new publications specific to North Carolina if they become necessary.
The ultimate source for EAB information is the website EmeraldAshBorer.info which is a collaborative effort of the U.S. Department of Agriculture Forest Service, Michigan State University, Purdue University and Ohio State University. On this site you can find out how to diagnose infested trees, learn about treatment options, and see what research is being on to help control EAB.
Diagnosing infested trees an important because trees can die quickly and become hazards. If you have a tree that shows signs of decline first be sure it is an ash tree. There is a publication to help you distinguish ash from other trees and distinguish EAB from other ash pests (http://ecoipm.files.
Another publication will help to zero in on specific EAB signs and symptoms (http://ecoipm.files.
There are insecticide treatments that will help protect trees from EAB. See “Insecticide Options for Protecting Ash Trees from Emerald Ash Borer”
There are a few products available to homeowners for protecting ash trees. But there are many considerations before committing to protecting a tree. See the “Emerald Ash Borer: Homeowner Guide to Insecticide Selection, Use, and Environmental Protection” (http://ecoipm.files.
The goal of this North Carolina Pest News was to alert you to some basic resources and our new website. I will start summarizing important information on the blog, http://ecoipm.com, so we can learn about this pest in bite-sized pieces. There are also a lot of regulatory issues that have not been cleared up yet. I have been in contact with North Carolina Department Agriculture & Consumer Services to try and figure out if infested trees need to be reported and what disposal requirements will be. Stay tuned . . .
A graduate student, Holden Appler, working with Dr. David Tarpy and me is looking for beehives to sample. He is investigating how urbanization affects honey bees and is looking for feral and managed hives from which he can collect bees. If you keep bees and would like to contribute to this research please contact me (firstname.lastname@example.org). Holden Appler would need to come and collect 60 bees from your hive. That’s it. We are also very interested in feral hives so if you know of a hive in a tree or a house or other place, please let us know. We are NOT in the business of bee removal. We would just collect 60 bees. Thanks.
