Emerald Ash Borer (Agrilus planipennis)
Emerald ash borer (EAB), Agrilus planipennis, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. The larvae feed in the cambium between the bark and wood, producing S-shaped galleries that girdle and kill branches and trees. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia.
Emerald ash borer has spread rapidly in the United States, killing millions of trees, and is expected to reach Vermont. White ash is one of the ten most common tree species in Vermont, so this insect will have a major impact when it becomes established in the state. The closest infestations are in south-central NH, Berkshire County, MA, New York's Hudson Valley, and just 30 miles north of the Vermont border in Quebec.
