Abstract
Total cones produced by western white pine, Pinus monticola Douglas, and total number attacked by the mountain pine cone beetle (Conophthorus ponderosae Hopkins = C. monticolae Hopkins) were counted during a 5-year study in the Sandpoint Seed Orchard, Sandpoint, Idaho. Cone production and level of beetle attack varied with clone, cone color class, and year. Certain western white pine clones were attacked at consistently higher rates than other clones. In years when cone production and percent cone attack were high, cone beetles showed preference for dark-colored over light-colored cones.This publication has 1 reference indexed in Scilit:
