Emerald ash borer dispersal in Maryland: go forth young pest

The emerald ash borer (EAB) (Agrilus planipennis Fairmaire), an exotic invasive pest from Asia, was introduced into Maryland in April 2003 via infested nursery stock shipped from Michigan to a nursery in southern Prince George's County. A nursery inspector from the Maryland Department of Agriculture (MDA) noticed EAB infested trees at the site in August 2003. A half-mile buffer zone was established around the nursery, and all ash trees within the quarantine zone were destroyed in an effort to eradicate the pest.
