When the European pine shoot moth was first found in North America in 1914, considerable interest was aroused by the discovery and no less fear regarding the potentiality of the insect as a menace to native forests and pine plantations. As the years went by and the pest appeared to be confined mostly to nursery stock and ornamentals, much of the original interest waned only to be rather suddenly revived by recent reports of widespread damage to certain pine plantations both in Canada and the United States.
