Synthetic verbenone has been evaluated as a tool for mitigating pine mortality due to bark beetle infestations. In western North America, efforts have concentrated on single tree or small scale stand protection, primarily from mountain pine beetle, Dendroctonus ponderosae Hopkins, infestations. Results have been favorable but inconsistent. spruce beetle. The Aerial Overview Survey (Maclauchlan & Buxton, ) found that the mountain pine beetle infestations are increasing, as are Douglas fir beetle populations, while western balsam bark beetle and spruce beetle infestations have remained steady.
