Agrilus planipennis, or Emerald Ash Borer (EAB), is a pest native to China that feeds under the bark of ash trees, eventually killing them. It is now known to be in at least 35 states and five Canadian provinces. The small metallic green beetles emerge from small D-shaped holes after feeding under the bark of ash trees. They leave serpentine galleries that are visible when the bark of the infested trees is removed.

Agricultural Impact

EAB has already killed hundreds of millions of North American ash trees, impacting the the timber and forest products industry.

Our Work

The Department has deregulated EAB. However, there are still some regulations pertaining to the movement of firewood, and other movement from known infested areas to areas thought to be free of EAB. These regulations are enforced by the New York State Department of Environmental Conservation and the US Department of Agriculture.


EAB is also regulated by New York State's invasive species regulations known as part 575. This invertebrate is listed as an invasive species in New York State.
