Published online by Cambridge University Press: 31 May 2012
Extract
Within the last few years parasites have become of increasing importance in the control of the oriental fruit moth, Grapholitha molesta Busck. Dr. Van Steenburgh, in a paper to be published in the Report of the Entomological Society of in Ontario for 1934, has reviewed their importance in Ontario and has shown that Glypta rufiscutellaris Cress. is the predominant native species, ranking next to the introduced Macrocentrus ancylivorus Roh. Cremastus minor Cush. is of secondary importance, while the other species occur only in small numbers.
