Abstract
The extent and intensity of the present infestation of the spruce budworm, Archips fumiferana Clem., in eastern Canada has become a problem of immense national concern (I). The necessity for further knowledge in formulating adequate control programmes has emphasized the importance of considering the possible utilization of natural insect parasites. As part of the more conprehensive study of control being carried on by the Federal Division of Entomology, the Dominion Parasite Laboratory in cooperation with the Forest Insect Unit instituted a programme of parasite introduction in 1943.Keywords
