Abstract: Of the more than 2000 exotic insects now established in the United States (US Congress 1993), more than 400 feed on trees and shrubs (Haack et al. 1997b, Mattsonet et al. 1994, Niemela and Mattson 1996).Several of these exotic insects have greatly altered forest ecosystems in the US (Campbell and Schlarbaum 1994, Ciesla 1993, Liebhold etal. 1995, Wallner 1996).
