Observational report on attack patterns by sequoia pitch moth and red turpentine beetle on pines, suggesting factors influencing susceptibility.
This article describes attacks of the Sequoia pitch moth and the red turpentine beetle on native and exotic pines in an arboretum that contains 70 species of the world's pines. Abundance of species and trees afforded an unusual opportunity for the observations here presented on relative susceptibility, parts of the tree attacked, influence of pruning scars, and other contributory factors.
