Scientific name: Agrilus planipennis. The adult emerald ash borer. Homeland / Origin: This alien invader is from northern China and Korea. It can also be found in eastern Russia, Japan, and Mongolia. It isn't a major pest of ash trees in its native range, but it sure is trouble in the United States.

One park in the has also found emerald ash borer activity. Northeast Indiana, central Indiana (Indianapolis area), northwest and central Ohio (Columbus area) have reported emerald ash borers. An infestation was discovered in north-central Illinois (Kane County) in June 2006.

And it’s starting again. Emerald ash borer, an Asian insect first identified in Detroit, Mich., in 2002, has become the most destructive forest insect to ever invade the U.S. Tens of millions of ash trees have already been killed in forests and swamps, along waterways and in urban, suburban and rural neighborhoods.

The ash borer apparently arrived in raw wood, and it was utterly jaw-droppingly stupid to allow solid raw wood from Asia to be imported to North America, given the known risks (that’s how other tree pests and diseases have arrived here).

The City of Kansas City, Mo., is advising residents that both the Missouri Department of Agriculture and U.S. Department of Agriculture have confirmed the Emerald Ash Borer as being in Kansas City.

In the early 1900s, people who lived in the eastern U.S. watched chestnut blight, an exotic pathogen, roll through, killing large and small trees and altering the hardwood forest forever.

Frequently Asked Questions about the Emerald Ash Borer Where did the Emerald Ash Borer beetle come from? The Emerald Ash Borer originated from eastern Russia, northern China, Japan and Korea. Before June of 2002, it had never been found in North America.

Ash is drought tolerant but tree will give up on weaker branches first. It could also be that it does not take much new Phloem Borer damage to kill off weakened branches. Also EAB is attracted to the stressed branches the most, like it is in its home range of Asia.
