The peach bark beetle, Phloeotribus liminaris (Harris), is native to North America and a reported pest of black cherry, Prunus serotina Ehrh., in the northeastern United States. Overwintering adults aggregate on live black cherry and create niches between the bark and cambium, resulting in a gum spot defect to affected portions of the sapwood. A strong relationship was identified between exterior gum spots and overwintering niches on the lower bole. Breeding activity was discovered in the crowns of live black cherry in low densities. The presence of black cherry slash, increased black cherry basal area, and warmer aspects within northern hardwood stands were associated with an increased abundance of peach bark beetle. Black cherry slash and increased black cherry basal area were associated with increased gum spot densities on residual black cherry in northern hardwood stands surveyed in New York State. As forest managers and landowners grow black cherry in greater abundance, understanding residual stand conditions will help mitigate future gum spot degrade caused by peach bark beetles.
