G 33 Spruce Budworm, choristoneura fumiferana clem. Although an increase in numbers of this insect occurred at three points in the southern part of Quetico Park population levels generally were low in the district New pockets of light infestation were found at Basswood Lake on the International Border and at Trout Lake south of Dawson Portage. Examination of balsam-fir foliage at four sample points in this area showed an increase in defoliation at one location at Lac La Croix (Table 11). Small numbers of larvae were collected at only two points elsewhere in the district.
