2016 Swede Midge Pheromone Monitoring - Olfert, Mori, Vankosky

In 2016, swede midge pheromone traps were deployed at 62 sites across the Prairie region to monitor adult populations of this brassica pest. Of the 62 trap sites, two were located in BC, 13 in Alberta, 29 in Saskatchewan (where positive swede midge identifications were made in 2007 and 2009), and 13 in Manitoba. The map below illustrates trap site locations in 2016.

None of the traps were positive for swede midge in 2016. 

We are grateful to all of the producers, agronomists, and cooperators who participated in the 2016 swede midge monitoring project. Without your assistance, we could not have supported such a thorough and widespread pheromone monitoring program. 

We also extend our thanks to Nancy Melnychuk (AAFC-Saskatoon) for organizing the program, distributing trapping materials, and processing returned sticky cards for adult swede midge.

Because of the serious threat that swede midge poses to canola production, it is vital that monitoring for swede midge continues across the Prairies. At this time, plans are being made for the 2017 swede midge monitoring program. Agrologists or growers interested in performing weekly monitoring in 2017 are encouraged to email either your provincial entomologist or the survey researchers hyperlinked below for more information.
