CFM surveys
CFM surveys in 2017 and 2018 recovered larvae at 135 of the 547 sites
sampled in the northern prairie regions of Manitoba, Saskatchewan, and
Alberta (excluding the Peace River Region) (Fig. 1), albeit in low
numbers (<4) at most sites. Areas with positive larval records
broadly corresponded to the black, dark grey, and, to a lesser extent,
dark brown soil zones where canola production is the highest (Fig. 1A &
B, Canola Council of Canada 2020b). These regions are bordered to the
north by parkland or boreal forest, and to the south by drier regions
where other Brassicaceae crops, such as mustard, are produced in higher
quantities than canola (Diverse Field Crops Cluster 2020).
