In the literature, there is a reference to what appeared to be a budworm outbreak in Maine about 1807. Evidence of the occurrence of a simultaneous outbreak in parts of Quebec and New Brunswick has also been found in the annual rings of living trees. Seventy years later between 1979-1885- another outbreak was recorded in the same general region. Then, in 1909 after a lapse of about thirty years, the Hon. C. E. Edwards called the attention of the Dominion Entomologist to a new and destructive infestation in the upper Gatineau region. From that day until this, outbreak after outbreak has occurred in Eastern Canada in a practically uninterrupted sequence.
