*NEW* Episode 13: Weather Effects: Predicting Pest Populations
James Tansey, Entomologist, Saskatchewan Ministry of Agriculture and Meghan Vankosky, Research Scientist, Field Crop Entomology, AAFC, Saskatoon, explain the relationship between weather and pests. They talk about how natural enemies can help control pest populations, especially when pests and their predators respond similarly to changes in weather. If pests and predators have conflicting responses to weather conditions, then pest populations can ‘escape’ control by their natural enemies.
Episode 12: Get a Jump on Grasshoppers
James Tansey, Entomologist, Saskatchewan Ministry of Agriculture, discusses the types of grasshoppers that cause damage, the conditions they prefer, how to get ahead of them, and the beneficial insects that provide control.

John Gavloski, Entomologist, Manitoba Agriculture and Resource Development, describes how beneficial insects contribute to farm profitability through services such as predation, parasitism, decomposition, pollination and weed seed consumption.
Episode 10: Good Bugs Relocate for Work
Héctor Cárcamo, Entomologist, AAFC, Lethbridge, AB, explains the strategic practice of introducing predatory insects to new regions to provide pest control. He shares examples of beneficial insects that have been relocated to Western Canada and what criteria is necessary to make the move.
Episode 9: Secret Agents in the Stubble
Jennifer Otani, Pest Management Biologist, AAFC, Beaverlodge, AB, shines a light on the mysterious secret agents lurking in crop stubble that attack wheat midge to defend crop yield and quality.
Episode 8: GOOD vs Pea Leaf WeEVIL
Meghan Vankosky, Research Scientist, Field Crop Entomology, AAFC, Saskatoon, SK, discusses the impact pea leaf weevils have on crops. She also shares best management practices, including scouting tips, and how beneficial insects can fight the weevil.
Episode 7: Powerful Parasitoids Better Than Fiction
Tyler Wist, Research Scientist, Field Crop Entomology, AAFC, Saskatoon, SK, gets in-depth on how Cotesia wasps parasitize wheat head armyworm, a damaging pest for cereal crops. As you’ll hear, the method of control sounds stranger than fiction.
Episode 6: Have Parasitoids Been Active in Your Fields?
Tyler Wist, Research Scientist, Field Crop Entomology, AAFC, Saskatoon, SK, explains what a parasitoid is and the function it serves in crops. Put simply, parasitoids are a specialized predator whose offspring will kill insect pests.
Episode 5: Keeping Wheat Stem Sawfly in Check
Scott Meers, Mayland Consulting, talks about the yield-robbing pest, wheat stem sawfly. He explains that one of its few controls is the Bracon sephi, an orange wasp that is less than a quarter inch long. He shares tips on how to protect this beneficial parasitoid.
Episode 4: Who’s After Grasshopper Eggs?
John Gavloski, Entomologist, Manitoba Agriculture and Resource Development, highlights four beneficial insects that help to control grasshopper populations by eating their eggs. He underscores the importance of protecting these egg eaters by choosing a more selective insecticide when pest thresholds are reached.
Episode 3: Cereal Leaf Beetles Be Gone
Haley Catton, Research Scientist, Cereal Crop Entomology, AAFC, Lethbridge, AB, talks about the importance of T. Julius as an effective means of cereal leaf beetle control. She says gaining knowledge about beneficial insects will help growers make more informed pest control decisions.
