Abstract: The incidence of twolined chestnut borer (TLCB), Agrilus bilineatus (Weber), and the canker fungus Hypoxylon atropunctatum (Schw. ex Fr.) Cke. was recoreded on dead oak (Quercus) trees !Y7 cm diameter at breast height (DBH) along an acidic deposition gradient from Arkansas to Ohio in 1989 and 1990. Approximately, one to three hectares of oak-hickory forests were inspected at each of seven study sites: one site in Arkansas, two in Illinois, two in Indiana, and two in Ohio. All sites were broadly analogous with respect to geology, soil, slope, aspect, and forest cover type.
