Abstract
Pleurotropis utahensis Crawford was first reported as a parasite of the wheat stem sawfly, Cephus cinctus Nort., by Crawford (2) prior to 1913. It has been recorded by Crawford (2) from Kimball and Salt Lake City, Utah; by Ainslie (1) from North Dakota; and by Gahan (5) from Missoula, Montana. It is one of several parasites of the wheat stem sawfly in the Prairie Provinces of Canada, where it has been recorded (7) (8) as far west as Sylvan Lake, Alberta. Criddle (3) (4), and in his original notes, records it from as far east as Boissevain, Manitoba. During the present study this parasite has been collected from sufficient locations that one might assume that it occurs throughout the area where wheat stem sawfly is found (6) in Alberta, Saskatchewan, and Manitoba.Keywords
