Establishment of Exenterus Spp. (Hymenoptera: Ichneumonidae), Parasites of the European Spruce Sawfly, Near Points of Introduction1

Published online by Cambridge University Press:  31 May 2012

Extract

Several species of parasites have played an important part in the biological control of the European spruce sawfly, Gilpina hercyniae (Htg.), in the Maritime Provinces. Most of the parasites were collected in Europe by the Imperial Institute of Entomology (9), and some material was collected in Japan through the cooperation of the United States Bureau of Entomology. The parasites were reared or propagated by the Dominion Parasite Laboratory, Belleville, Ontario (12), and liberated by officers of the Dominion Entomological Laboratory, Fredericton, assisted by other government and company services.
