Extract

The occurrence of midges on jack pine, Pinus banksiana Lamb., in Manitoba has been reported by Lejeune (4), Barker and Wong (1), and Prentice and Hildahl (5, 6). The Forest Insect Survey also reported a species of Retinodiplosis on jack pine in Ontario, and Barnes (2) suggested that this may have been R. resinicola (Osten Sacken). This name was also provisionally assigned to a species found near Stead, Manitoba, in 1956 (7). Vockeroth (8) now shows that Retinodiplosis Kieffer is a synonym of Cecidomyia Meigen, which is represented by at least two species on jack pine in Manitoba and Saskatchewan. These are C. reeksi and C. banksianae. The former is the more common and undoubtedly was the species most frequently represented in the early reports of pine midges in Manitoba.
