Some growers are reporting high numbers of adult flea beetles. Adults emerge from pupae in late July and August and overwinter to feed on young canola seedlings the following spring. These same adults do feed now, but Julie Soroka and Larry Grenkow (Can. J. Plant Sci. 2012: 97-107) found that flea beetle feeding on canola in late-summer is rarely an…
