Pest Alert Hemlock Woolly Adelgid NA-PR-09-05

Native to Asia, the hemlock woolly adelgid (Adelges tsugae) is a small,aphidlike insect that threatens the health and sustainability of eastern hemlock(Tsuga canadensis) and Carolina hemlock (Tsuga caroliniana) in theEastern United States. Hemlock woolly adelgid was first reported in the Eastern United States in 1951 near Richmond, Virginia. By 2005, it was established in portions of 16 States from Maine to Georgia, where infestations covered about half of the range of hemlock. Areas of extensive tree mortality and decline are found throughout the infested region, but the impact has been most severe in some areas of Virginia, New Jersey, Pennsylvania, and Connecticut.
