Challenges Resulting from the Emerald Ash Borer

Agrilus planipennis, commonly known as the emerald ash borer (EAB), is a green jewel beetle native to eastern Asia that feeds on ash species. In its native range, it is typically found at low densities and is not considered a significant pest. Outside its native range, it is an invasive species and is highly destructive to ash trees native to North America. Prior to EAB being found in North America, very little was known about EAB in its native range; this has resulted in much of the research on its biology being focused in North America. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control.
