Abstract
Several types of pheromone-baited traps have been used for trapping males of the spruce budworm, Choristoneura fumiferana (Clem.). Most pheromone traps have sticky surfaces for capturing attracted moths; however, the sticky surface often becomes saturated with moths, moth scales, and debris, thus diminishing the traps' effectiveness. At high population densities, saturation may occur within a few hours after the traps are placed in the field. The Pherocon 1CP® trap found most effective by Sanders (1978) functionally saturates after about 50 spruce budworm moths are caught (Houseweart et al. 1981).
