It’s no secret that the striped flea beetle is a tougher opponent than the more common crucifer flea beetle. This canola pest tends to emerge earlier than the crucifer type and isn’t as easily killed by commonly used seed treatments. That does not mean, however, that the striped flea beetle is resistant to neonicotinoids, as has been rumoured.
In this video taken at this month’s Manitoba Agronomists Conference at Winnipeg, Man., John Gavloski, provincial entomolgist with MAFRI, explains more about the difference between striped and crucifer flea beetle, why the insect is not actually displaying resistance and when to scout for the pest.
