The number of Zeiraphera canadensis adults caught with synthetic pheromone in models 1, 2 and 3 of the Multi-Pher® insect trap were compared in 31 young white spruce stands. Two types of synthetic pheromone holders were used. Models 1 and 3 Multi-Pher® traps performed equivalently and yielded the greatest number of catches; the model 2 caught less males. Considering the relatively large number of females caught, sex determination of the trapped adults is desirable.
