Emerald Ash Borer (EAB), Agrilus planipennis
The emerald ash borer (EAB), Agrilus planipennis, is one of the most serious invasive species threatening our ash resources and forests. All species of (Fraxinus) ash trees, but not (Sorbus) mountain ash, that grow in Maine are susceptible to injury and death by the emerald ash borer.
EAB was first found in Aroostook County. (Madawaska, Frenchville, and Grand Isle), and York County (Acton, Berwick, and Lebanon), ME in 2018.
