Extract

During the latter part of June, 1955, a larva of the European corn borer, Pyrausta nubilalis (Hbn.), dissected from overwintered corn stalks in experimental plots at St. Jean was observed to be parasitized by hymenopterous larvae. These were reared to the adult stage and were then identified by Dr. O. Peck, Entomology Division, Ottawa, as of Dibrachys cavus (Wlkr.). This parasite has only once been reported from North America (Blickenstaff et al., 1953, p. 377) and once from Russia (Thompson, 1946, p. 517).
