NDSU Extension Cropping Specialist Lesley Lubenow is seeing increasing numbers of striped flea beetles in canola field surveys. “It depends on the area, but at one in Towner County, about 20 percent of the flea beetles are striped. That’s quite a bit higher than people thought.” Lubenow says the striped flea beetle is more difficult to manage. Research is underway. “There is research out of Canada that shows the striped flea beetles are better competitors in the presence of neonicotinoid seed treatments. That basically means they’ve survived them better than others. They’re the ones you’d want to pick for your playground kick ball team. They’re better players.”
