The destructiveness of the spruce budworm, Archips Fumiferana (Clem.), is well known. It has done more damage to the spruce and balsam forests of Eastern Canada than any other insect. Periodic outbreaks have occurred apparently as far back as the beginning of the last century and probably before that. Owing to the vast area involved, many of them relatively inaccessible, our knowledge of the extent of those outbreaks in the past is very incomplete, and only in recent years, with the aid of the Forest Insect Survey, has it been possible to record them in any detail.
