Aphidius smithi Sharma and Subba Rao is the most important parasite of the pea aphid, Acyrthosiphum pisum (Harris), in North America. In 1958, it was imported into the United States from India to control the pea aphid and was subsequently released and recovered in most of continental United States except the Gulf Coast States and Texas (Halfhill et al. 1972). Mackauer and Finlayson (1967) reported that the parasite was present in Ontario, Quebec, and British Columbia and had been released but not recovered in Nova Scotia. A. smithi has never been released in western Canada nor been found on the Canadian prairies before 1970.
