Although the European pine shoot moth is well known as a pest of pines where winters are moderate, particularly in southern Ontario (1, 2, 3, 6), its occurrence in the Province of Quebec has been sporadic and confined chiefly to the more southern regions. There have been occasional reports of this insect in Montreal since 1931 and in Grand' Mère since 1934, but it was not until 1954 that is was discovered in Quebec City. Since that time, however, it has been recorded from several other localities. In 1958, it was found in a nursery at Sayabec, in the Matapedia Valley.

Following its initial discovery in Quebec City, a survey of the immediate vicinity revealed that the infestation was not more than three to four years old and limited to small areas. The insect was mainly restricted to the small ornamental pines, but the infestation was sufficiently severe to warrant an investigation of the principal factors of natural control affecting all stages.
