AAFC posts new IPM video

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.

AAFC entomologists 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.

I would be remiss 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.
