Late-season flea beetles

Flea beetle

Flea beetle numbers this late in the season are higher than we’ve seen in years, which could point to higher numbers next spring.

For this year’s canola crops, don’t take any action unless you see flea beetles feeding on pods over a broad number of acres. Entomologists have not set thresholds for late season flea beetle feeding, but it’s generally believed that numbers have to be very high — perhaps 100 per plant — before economic losses occur.
