Abstract
During the past 25 years the wheat stem sawfly,Cephus cinctusNort., has become one of the most destructive pests of wheat in the Prairie Provinces. Annual losses in the wheat-growing area of Saskatchewan have been estimated as high as 17 million bushels (King and McDonald, 1944). There are, however, several native parasites of this pest, and of theseBracon cephi(Gahan) [Microbracon cephiGahan] is the most important. In some areas this parasite has been very effective in reducing severe sawfly infestations.Keywords
