The spruce budworm (SBW) (Choristoneura fumiferana) is the most serious pest affecting the forests of eastern North America. Records indicate that SBW outbreaks are cyclic – occurring every 30 to 40 years. The last extensive outbreak in eastern Canada reached its peak in the 1970s, damaging more than 50 million hectares. An outbreak is currently occurring in Quebec, and populations are increasing in northern New Brunswick. Issued also in printed form. gccst Insecticides Canada. Natural Resources Canada.
