Extract

Extensive stands of young tamarack throughout the forested areas of the Prairie Provinces are currently menaced by the depredations of this serious defoliator. Owing to the importance of the insect, this paper was prepared with the object of: (1) reviewing briefly available information concerning the present outbreak in the Prairie Provinces, (2) clarifying some of the main issues frequently raised, and (3) describing the investigations in progress in the Prairie Region.
