Abstract
Glypta fumifermae (Vier.) (Ichneumonidae) and Apanteles fumiferanae Vier. (Braconidae) are two of the most common parasites of immature larvae of the spruce budworm, Choristoneura fumiferana (Clem.). Females parasitize the minute host larvae in the fall. Their eggs or larvae lie dormant within the hibernating host larvae, and then resume development in the spring, when the spruce budworm larva breaks hibernation and commences to feed. The budworm host is killed by Apanteles usually when it is in the fifth larval instar or by the Glypta when it is in the sixth instar.Keywords
