Assessing the Impact of Swede Midge on Canola Production in the Prairies & Ontario

Researcher:

Dr. Rebecca H. Hallett, School of Environmental Science, University of Guelph

Project Code:

CARP 2005-14

Final Report:

February 2008

Summary:

Ecoclimatic modeling indicates that most of Canada is suitable for establishment of swede midge, including most of Saskatchewan. In 2007, swede midge were found in three fields in Saskatchewan for the first time. Although researchers expect the insect will become established and become a regular pest of canola in the Prairie provinces, they do not expect the populations to reach the high levels found in Ontario.
