The antiaggregation pheromone verbenone was tested at two release rates against unbaited controls for effects on mountain pine beetle, Dendroctonus ponderosae Hopk., dispersal and attack in a lodgepole pine Pinus contorta var. latifolia Dougl. stand. Number of beetles trapped, number of attacked trees and number of attacks were measured. There were no significant differences between the two verbenone treatments in any of these variables. Means of all experimental variables were lower in the verbenone-treated plots than in the control plots but only the difference in the number of beetles trapped was statistically significant. Numbers of clerid beetles trapped appeared to be unaffected by the treatments.
