Abstract
The balsam woolly aphid, Chermes piceae Ratz. (Homoptera: Chermidae), was accidentally introduced into North America from Europe about 1900 (Balch 1952). The aphid is now a serious pest of Fraser fir, Abies fraseri (Pursh)Poir., in the Southern Appalachians. Since its discovery in Northo-1957 (Speers 1958), the aphid has killed thousands of trees annually. Fraser fir is an especially, valuable aesthetic resource along the Blue Ridge Parkway, in the Great Smoky Mougtains National Park, and Mt. Mitchell State Park where it is viewed by millions of persons annually.
