Emerald Ash Borer
The Emerald Ash Borer (EAB) Agrilus planipennis Fairmaire is an invasive, wood boring beetle native to Asia that feeds on and eventually kills all species of Ash. The EAB was first found in North America in 2002 near Detroit and since has spread to 13 states and two Canadian provinces, killing hundreds of millions of Ash trees in rural and urban settings. EAB has been found in a number of New York State counties, and a quarantine zone is in effect to prevent its further spread.
