Abstract: Hemlock woolly adelgid, an aphid-like insect from Japan, is a destructive pest of hemlock in the eastern United States. Populations of this adelgid can be managed successfully in ornamental settings using an approach that integrates various cultural, chemical and biological control methods. This report describes the insect, including its life cycle, dispersal capability, patterns of infestation, and the damage it causes, and discusses ways in which infested ornamental hemlocks can be maintained in good health.
