Validating economic thresholds for flea beetles can be tricky — especially when we know the damage the insect can do to the canola crop. Héctor Cárcamo, research scientist at Agriculture and Agri-Food Canada (AAFC) at Lethbridge, Alta., recently completed a study that confirms an economic threshold.

Flea beetles are a common insect pest in early growing canola across the Prairies. There are two important species of concern for canola (and mustard) growers: the striped flea beetle and the crucifer flea beetle. “The feeding is indistinguishable, but the striped flea beetle comes up earlier,” says James Tansey, provincial entomologist with Saskatchewan Ministry… Read More

If you were farming on the western Canadian Prairies in 2019, you’ll most likely shudder at the thought of flea beetles, knowing how rampant they ran throughout the spring.

There are few things as frustrating as spending untold hours of preparation and seeding (and finally some rain!) only to have a host of insects crawl or fly in and eat the crop’s yield potential. In this episode of the Canola School, provincial entomologist for Saskatchewan’s Ministry of Agriculture, James Tansey, gets outside to talk… Read More

As temperatures warm, fields across the west are starting to see flea beetle emergence, and cotyledon defoliation. And that has producers wondering about when to take action. “There’s been some discussion about different threshold levels,” says Errin Willenborg, agronomist with Federated Co-op Ltd.
