The pheromone mask released by female Dendroctonus pseudotsugae Hopk. after the male stridulates stops aggregation of beetles in flight, but not arrestment of males, in an interaction of chemically and sonically induced behavior. This masking is viewed as a mechanism for survival through the regulation of attack and as a critical part of premating behavior.
