The budworm larvae primarily defoliate balsam fir and white spruce. Every 30 to 50 years large scale sbw outbreaks cause widespread top kill and tree mortality. Mature and over mature balsam fir dominated stands are most severely damaged. Susceptible stands often lose 60 to 80 percent of the fir and 20 to 40 percent of the spruce.
