Extract
In a survey of infestation by the European corn borer, Ostrinia nubilatis (Hbn.), in Essex County, Ontario, in 1957, officers of the Chatham laboratory found several hymenopterous pupae associated with dead borers. Adults emerged in the laboratory and were identified by Mr. G. S. Walley, Entomology Division, Ottawa, as of Horogenes punctorius (Roman), an imported parasite of the borer. This is the first record of its establishment in Canada.
