The 2016 Annual Peace Canola Survey was completed by Agriculture & Agri-Food Canada staff based at Beaverlodge and Saskatoon.
Since 2003, the annual survey has been performed with the main objectives of
(i) collecting insect pest data throughout the region and
(ii) to detect introduction of the Cabbage seedpod weevil into the Peace River region.
In 2016, a total of 156 commercial fields of Brassica napus (e.g., each field ≥80 acres in size) were surveyed and no B. rapa was encountered.
Fields were surveyed by sweep-net using 50 – 180° sweeps on the following dates in these areas:
- July 5 near Whitelaw, Berwyn, Grimshaw, Dixonville, Manning, Hotchkiss, Hawk Hills, Notikewin, Blue Hills, Buffalo Head, La Crete.
- July 6 near Fort Vermilion, Blumenort, Valhalla, La Glace, Westmark, Woking, Spirit River, Blueberry Mountain, Silver Valley, Bonanza, Bay Tree, Beaverlodge, Halcourt, Wembley, Grande Prairie, Clairmont, Sexsmith, Teepee Creek, Bezanson, Dimsdale, Huallen, Fairview, Vanrena, Hines, Creek, Worsley, Eureka River,

Sweep-net samples were frozen then processed to generate data for a total of 21,278 arthropods which were identified and categorized into 38 taxa. The 2016 summary includes 15 economically important pests of canola reported from 156 surveyed canola fields plus data related to rotational practises in the Peace River region.
