Forest entomologist Glenn Kohler (Washington State Department of Natural Resources) examining verbenone pheromone pouches on a whitebark pine. The pouches didn’t work well since there are pitch tubes from mountain pine beetle attacks and fading needles. Aerial observer Calibration and Conformity training.
Note: Verbenone can be used as a short-term treatment to protect individual pine trees or stands from mountain
pine beetle (MPB) attack. MPB naturally produces verbenone as an anti-aggregation pheromone to disperse adult beetles away from a fully colonized tree.
