Extract

The spruce budworm Cacoecia fumiferana Clem. is a tortricid moth which periodically appears in vast numbers in the spruce-balsam forests of Canada and the northern United States. When these outbreaks occur, the balsam fir is often killed over areas totalling thousands of square miles. Therefore, this insect has conle to be regarded as one of the most serious enemies of pulpwood forests and has attracted a good deal of attention from forest entomologists.
