The pea leaf weevil can cause devastating economic losses to both peas and faba beans. Though the adult beetles feed on these crops after overwintering in perennial legumes, it is actually the larvae that cause the greatest damage. Larval feeding occurs on Rhizobium nodules for roughly six weeks. This may limit or completely inhibit nitrogen-fixation… Read More

Swede midge larvae and symptoms were spotted in much of northeastern Saskatchewan this summer, concerning producers and agronomists alike. This isn’t the first time there has been concern over their movement, however. Three adult midge were found in Saskatchewan in 2007, only seven years after first being identified in Ontario, where their spread has been… Read More
By now you’re fully aware of the importance of monitoring insect pests in your canola. So, you’ve collected and assembled your sweep-net, now what? The standard technique for sweeping is one 180 degree sweep for every quick step through the canola field (accompanied by the odd fall, of course). Sounds simple (and perhaps slightly embarrassing), but… Read More
Have you been keeping an eye on the bertha armyworm monitoring trap numbers in your area? As we crawl closer to mid-July, it’s important to be aware of regional risks, and have a good understanding of proper scouting techniques and spray timing. “You’re going to have your best success spraying at night,” says John Gavloski, provincial entomologist with… Read More
This spring I listened in on the Saskatchewan Ministry of Agriculture’s Alfalfa Weevil Webinar. I assume I’m not the only farmer out there who had little knowledge of the alfalfa weevil before the webinar, let alone any idea of how much of a problem it is becoming. Let’s just say that if you have yet… Read More
Tune in to Twitter tomorrow at 10 a.m. (mountain) to participate in the second #AbBugChat.

Anyone with a Twitter account can participate in a chat. Simply… Read More
If you are aggravated by puns or organisms belonging to the family Apidae, a warning: this article may bug you. But honey, I’ll try not to drone, if you promise to bee open-minded. There has been a lot of media coverage on the recent and very controversial propesed two-year suspension of neonicotinoids in the European… Read More
Alberta Agriculture wants your worms — cutworms, that is. In an effort to map out changing populations of various cutworms and to pinpoint cutworm feeding in new areas or at non-traditional times of the year, the Canola Council of Canada in concert with various provincial pest monitoring agencies and research scientists are asking for cutworm… Read More
The first few days of May brought a surprise! The Twitterverse lit up with reports of cutworms in southern Alberta. The first report came in on a new alfalfa stand. In alfalfa we normally expect that the cutworms will be redbacked but in this case they were army cutworm. The second field was a winter… Read More
