B2 An extensive virus recovery program carried out in Lake Simcoe and Lake Huron districts in 1965 by Department of Lands and Forests personal in co-operation with Forest Research Technicians provided a supply of virus for use in 1966. Biological control involving the importation and release of European parasites was introduced in 1940. Eleven species were imported up to 1962. A recovery program was initiated by the Forest Insect Survey in Southern Ontario to study the establishment and spread of the parasites. The results of the survey completed in 1962 were reported by A. H. Rose and W. L. Sippell in the Canadian Entomologist, Volume 98, Number 1, 1966. "Cocoons of the European pine sawfly were exposed in rodent-proof trays to determine what parasites attack this pest in southern Ontario. Exposures showed that two introduced parasites, Dahlbominus fuscipennis (Zetterstedt) and Pleolophus (=Aptesis) basizonus (Gravenhorst), are firmly established throughout the distribution of the host. The former parasite has spread more than 30 miles and the latter at least 70 miles in approximately 20 years. The number of trays found by each species varied considerably with each locality. In general, the number of native parasite species obtained tended to increase with the age of infestation, with Mastrus aciculatus (Provancher) being the most prevalent (Table 2), Nine other native parasites occurred sporadically and in small numbers."
