Michigan Department of Ag Press Release:
New exotic pest identified in Michigan's ash trees; State issues quarantine to control, prevent its spread

July 16, 2002 - Michigan and federal officials today announced the discovery and identification of a new exotic pest from Asia--Agrilus planipennis or the Emerald Ash Borer--in five Southeast Michigan counties that affects ash trees. In response, state agriculture officials have issued a quarantine on all ash trees and timber products in the affected counties to help prevent and control the spread of this pest. Under this quarantine, ash trees, branches, logs, and firewood may not be moved outside the affected area unless certified for movement by the Michigan Department of Agriculture

The Emerald Ash Borer, a pest belonging to a group of insects known as metallic wood-boring beetles, is not native to Michigan or anywhere in the United States.

Homeowners and landscapers in Southeast Michigan have been plagued by loss of ash trees for the past couple of years. Specialists initially determined much of the problem was due to a combination of disease, drought, and poor soils. This new insect is likely another reason for the ash trees' decline.

Emerald Ash Borer adults are dark metallic green in color, 1/2 inch in length and 1/16 inch wide. Larvae are creamy white in color and are found under the bark. Their appearance typically goes undetected until the trees show symptoms of being infested--usually the upper third of a tree will thin and then die back. This is usually followed by a large number of shoots or branches arising below the dead portions of the trunk.

Homeowners, landscapers, and arborists outside of Livingston, Macomb, Oakland, Washtenaw, and Wayne counties are encouraged to be on the lookout for this new exotic pest and report any signs or dying ash trees to the local MDA or MSU-E office, or via the state's toll-free Emerald Ash Borer Hotline at 866-325-0023
