Notes: Herbivory by two exotic hemipterans, hemlock woolly adelgid (HWA), Adelges tsugae Annand (Adelgidae), and elongate hemlock scale (EHS), Fiorinia externa Ferris (Diaspididae), have very different effects on eastern hemlock, Tsuga canadensis (L.) (Pinaceae). Resource allocation effects likely underlie the rapid and dramatic decline of hemlock in response to HWA feeding, and the considerably milder effects of EHS feeding.
