Weekly Update (May 11, 2017; Wk 02) - Diamondback moth

Diamondback moth (Plutellidae: Plutella xylostella) - Pheromone traps attracting male Diamondback moths are being deployed across the prairies.  High altitude air masses are tracked by AAFC-Saskatoon Staff (forward and backward trajectories).  These wind events have the potential to aid the movement of diamondback moth and aster leafhoppers northward on to the Canadian prairies from Mexico, southern and central USA as well as the Pacific Northwest.  Diamondback moth pheromone traps deployed across the prairies confirm their arrival - many thanks to the people who deploy and do the weekly monitoring!

Alberta Agriculture and Forestry has a live 2017 map reporting Diamondback moth pheromone trap interceptions.  Watch for updates from Manitoba and Saskatchewan as growing season progresses.

Biological and monitoring information for DBM is posted by Manitoba Agriculture, Food and Rural DevelopmentSaskatchewan AgricultureAlberta Agriculture and Forestry, and the Prairie Pest Monitoring Network.  

More information about Diamondback moths can be found by accessing the pages from the new "Field Crop and Forage Pests and their Natural Enemies in Western Canada: Identification and Field Guide".  View ONLY the Diamondback moth page but remember the guide is available as a free downloadable document as both an English-enhanced or French-enhanced version.
