Earlier this growing season the Field Heroes campaign began. The campaign is supported by Western Grains Research Foundation and is aimed at increasing awareness of naturally occurring arthropods that are beneficial to growers owing to their ability to consumer insect pest species!
Screenshots of true armyworm from the Cutworm Field guide are also shown below:
Cutworms are part of Canadian agriculture on the Prairies. Most of the time they are of little concern but outbreaks do occur from time to time, causing significant economic damage if not controlled. Cutworm outbreaks can range from small patches of clipped or missing plants in individual fields to widespread areas with entire quarter
sections needing re-seeding.
Cutworm management starts with identification – knowing what species is at work in your fields helps unlock information
that improves cutworm scouting and management. Knowledge of cutworm biology, behaviour, preferred habitat, impacts of weather and interaction with its natural enemies will all improve scouting
techniques and pest management decisions for growers.
Just released, the Cutworm Pests of Crop on the Canadian Prairies – Identification and Management Field Guide describes the economically important cutworm pests in detail and provides the information needed to manage them.

the Control of Arthropod Pests of Livestock, Poultry and Farm Buildings in
Western Canada”. This is an 70-page guide and a valuable resource providing an updated list of insecticides used to control pests of
livestock. The Guide has been posted as a downloadable pdf file.
When encountering insects found in prairie crops, I quite often don’t know if I’ve found a ‘good’ or a ‘bad’ insect. In these instances, I feel like Glinda the Good when she asked Dorothy, ‘are you a good witch, or a bad witch?’ Some are ‘good’ insects (predators, parasitoids, pollinators, decomposers) and others are ‘bad’ (defoliators, sap suckers, seed eaters, root eaters, disease vectors). And of course there’s also the great grey middle where some insects have a balance of good and bad traits, while others are seemingly and completely benign. Many times, you can’t tell simply by their appearance which category an insect falls in (unlike Glinda in identifying a bad witch: ‘Only bad witches are ugly.’). Especially when you encounter their adult form as it’s often the larvae or nymphs that cause most of the damage.
study many aspects of the insects that make their home in our crops and nearby
land. One of those aspects is how the ‘good’ insects contribute to the
producers’ bottom line in terms of the pest control services they provide. Economists estimate that for
every $1 invested in Integrated Pest Management research, the industry gets
back about $15 in benefits. For a brief look at some of the work AAFC
entomologists do in Saskatchewan, make some popcorn, sit back and watch our new video.
if I didn’t add that AAFC entomologists partner with provincial, university, industry
and private entomologists in the region and across Canada to discover, monitor and
publicize the latest findings and trends in crop pests and beneficials.

Today Alberta Agriculture & Forestry posted the link to their online 2016 Cutworm reporting tool which is located at: http://www1.agric.gov.ab.ca/$Department/deptdocs.nsf/all/prm13779
Cutworm reports are mapped in real-time to help keep the agricultural industry informed.
Field Crop and Forage Pests and their Natural Enemies in Western Canada: Identification and Field Guide (2015) by Hugh Philip is a new publication from Agriculture and Agri-Food Canada. Two downloadable (~8 MB) versions of the complete field guide are available:
Have you used the new Canola Insect Scouting Chart?
- The Canola Insect Scouting Chart helps growers anticipate and identify insect pests according to relative crop stages.
- Insect pest names have been hyperlinked to pages published within the new “Field Crop and Forage Pests and their Natural Enemies in Western Canada: Identification and Field Guide”.
- Growers can link to photos and to fact sheets by clicking each insect name on the chart.
