What trees are attacked by the emerald ash borer?
All species of ash are attacked by this insect. Our black, blue, green and white ash trees and their many cultivars are all susceptible to attack. All of these trees will be killed by an emerald ash borer infestation. The only tree showing some tolerance to attack is the Manchurian ash, a tree native to the region of Asia where the beetle is found. Emerald ash borer does not attack mountainash, ash-leaf maple or prickly ash. These trees are not related to ash. How can I tell if my tree is infested? Again, it is important to point out that the emerald ash borer has not yet been detected in South Dakota (May 28, 2009). However ash trees exhibiting the following symptoms may be infested. Look for ash trees that have some dieback or are standing dead. Oftentimes these trees will have the bark shredding off due to the tremendous number of woodpeckers feeding on the larvae beneath the bark of the infested tree. If the bark is pulled off the tree you should be able to find S-shaped tunnels on
