The coleopteran fauna on northern red oak, Quercus rubra L., was assessed at three sites (Beetree Ridge, Mt. Sterling, Rich Mt.) in the Great Smokey Mountains National Park, and at one site at the University of Tennessee Arboretum. These four sites represent elevation gradients ranging from 262-1465 meters. The canopy of one randomly selected tree per site was sampled monthly using a Dyna-fog Golden Eagle fogger. Specimens (<16,000) were collected, processed, and identified for the sampling periods. Species diversity was assessed using the Shannon-Weiner Diversity Index. Of the 163 species identified, the highest number specimens (42.2% of total collected) was obtained at the Rich Mt. site (841 meters). Specimens of the Asiatic oak weevil (Cyrtepistomus castaneus (Roelofs)) comprised 17.8% of all specimens collected. Results of this study will assist in developing management strategies in northern red oak dominated forests to enhance Tennessee forests.
