Psocopteran Species Associated with Eastern Hemlock in the Southern Appalachians

Eastern hemlock, Tsuga canadensis (L.) Car riere, comprises a vital component of biological diversity (Jordan & Sharp 1967; Lapin 1994; Tin gley et al. 2002; Buck 2004; Buck et al. 2005; Dill ing et al. 2007; Dilling et al. 2009) and economi cal (Travel Industry Association 2006; Woodsen 2001) and environmental stability (Evans 2002; Snyder et al. 2004) within its geographical range. Hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), is an exotic insect species capable of rapidly reducing populations of eastern hemlock throughout the eastern United States (McClure & Fergione 1977; Buck et al. 2005; Ellison et al. 2005). As such, documenting the biodiversity of insects associated with this host tree is imperative. More than 400 insect species have been recorded to be associated with eastern
