Abstract
Apanteles fumiferanae Vier. and Glylpta fumiferanae (Vier.) are two well known hymenopterous parasites of the spruce budworm in Canada. While studying a microsporidian disease of the budworm caused by Perezia fumiferanae Thom. (Thomson, 1955) it was observed that occasionally the microsporidian and one of the hymenopterous parasites occurred together in the same host. This paper is a report of a study of the effect of the microsporidian on the hymenopterous parasites.
