The 2019 Prairie-Wide Risk and Forecast Maps can be viewed and downloaded here.
Economically significant insect pests are monitored across the Canadian prairies each year, thanks to extensive networks of collaborators and cooperators. In 2018, that effort culminated in 5764 survey stops across Manitoba, Saskatchewan, Alberta and the BC Peace!
Here’s what’s included in the PDF file:
- Average tempature, average precipitation, and modeled soil moisture for 2018.
- A series of geospatial maps are included for each of the target species; the current map is followed by the previous 4 years.
- For some species, the geospatial maps represent 2018 distributions used to infer risk in the coming 2019 growing season. Data is included for bertha armyworm, cabbage seedpod weevil, pea leaf weevil, wheat stem sawfly and diamondback moth.
- For wheat midge and grasshoppers, the geospatial maps forecast or predict expected populations or risk for the 2019 growing season.
The historical Risk and Forecast Maps (2015-2019) are available for review.
These maps help the agricultural industry prepare to manage insect pests across the prairies and helps growers make crop choices and anticipate scouting priorities within their growing region. From May to July, the Weekly Updates will provide in-season updates, predictive model outputs plus scouting tips and links to relevant information.
Thank you to the many people who monitor each growing season!
