flea beetles

Be on the lookout for three early-season crop pests

MAFRD entomologist John Gavloski has advice on flea beetles, 
cutworms and wireworms for Manitoba farmers

Be on the lookout for flea beetles, cutworms and wireworms, all of which can take a bite out of yields early in the growing season, says John Gavloski, entomologist with Manitoba Agriculture, Food and Rural Development (MAFRD). Canola is especially vulnerable to flea beetle damage during the cotyledon to second true-leaf stage, Gavloski said during


Oriental fruit fly

A destructive crop pest with many different names

The finding is expected to help with international biosecurity and control

A global research effort has finally resolved a major biosecurity issue: four of the world’s most destructive agricultural pests are actually one and the same. For 20 years, some of the world’s most damaging pest fruit flies have been almost impossible to distinguish from each other. The ability to identify pests is central to quarantine,

Manitoba Insect and Disease Update: July 25, 2014

Manitoba Agriculture’s weekly Insect and Disease Update is now available. Visit the MAFRD website for full text and images. Highlights: Goss’s wilt and leaf blight disease are showing up in corn. Ergot disease infection is now showing up in fall rye and grasses. Blackleg infection on lower stems/roots on canola is showing up. Downy mildew on sunflowers is


Pest surveillance branch update June 19, 2014

Alberta Insect Pest Monitoring Network – The wet weather will favor disease development. Many fungal and bacterial diseases will thrive with the continuous moisture available. On his weekly insect update on Call of the Land, Scott Meers talks about cutworms, scarab beetle, and bertha armyworm. Diseases to watch for under these conditions at this time of year

Swede midge threat looms over Manitoba canola crops

A deceptively tiny bug can wreak non-stop havoc in canola

If you thought clubroot was scary, get ready for Swede midge — a voracious mosquito-like bug that can wreak havoc with your canola yields. First found in North America in 2000, and has appeared in low numbers in Manitoba in 2007 and 2013, said Julie Soroka, a Saskatoon-based entomologist with Agriculture and Agri-Food Canada. “The

Temperature swings hard on insects

The research is changing how scientists view the effect of climate change on plants and animals

Many species of insects, including a wasp commonly used for biocontrol in Canada, are at risk due to increasing dramatic temperature changes related to global warming. Increasingly extreme swings in temperature may put some insects at higher risk than previously thought, according to a new study published today in the Proceedings of the Royal Society
