Description: In planning forest management of spruce-fir forests in the Northeast, the possibility of recurring epidemics of the spruce budworm (Archips fumiferana) must be considered. Investigations of this insect must take into account not only the effects of defoliation on mortality, but also the growth losses that result from partial defoliation.
