The wheat midge is orange in colour and closely resembles a mosquito because of its small size.

Going, not gone: Some hot spots remain for midge

Recent low wheat midge counts no guarantee the problem won't return

Wheat midge populations on the Prairies have been declining for the past few years, but a researcher specializing in insect pests says farmers need to remain vigilant about the threat they pose to crops. “My advice (to farmers) is don’t turn your back on wheat midge, even if you are in a (low level) green […] Read more

Wheat midge 101: the basics of scouting

Growing soft white wheat or a non-midge-tolerant variety? Get ready to scout

It’s smaller than a mosquito, but more of a headache for Prairie farmers — wheat midge might look innocuous, but it can cause significant crop damage in Western Canada. Since midge-tolerant spring wheat varieties have become widely available, midge scouting has become a thing of the past for many Prairie farmers. However, with only one […] Read more

A new species of midge lands on the Prairies

Researchers say this 
new “anonymous” midge is not an imminent concern, but it’s worth watching

An anonymous midge species has been identified in Saskatchewan and central Alberta. The new species is similar to Swede midge (a species already present in Saskatchewan), but to this point does not appear to have caused significant, widespread damage in canola crops. Researchers are still trying to find out more about the as yet unnamed […] Read more

Midge scouting in canola

Scouting is an important component of management. If you don’t know what’s in your field, you can’t evaluate what control measures to use. Yearly scouting is needed to assess what pests exist in fields, as populations don’t always remain constant. For example, in 2016 there were higher counts of cutworm but lower incidence of Bertha […] Read more

Anonymous midge appears in Prairie canola

Canola crops in northeastern Saskatchewan and east-central Alberta have run up against a potential pest problem so new it doesn’t yet have a name. Researchers with Agriculture and Agri-Food Canada, the University of Guelph and the Canadian Food Inspection Agency have reported a new species of midge damaging canola crops in those areas. The species […] Read more

The severity of wheat midge this season will depend on the weather.

Protect yourself against wheat midge

Wheat midge may be on the rise this year, especially in southeastern Saskatchewan

Farmers in most areas of Saskatchewan need to be aware of wheat midge, says Scott Hartley, Sask­atch­­e­wan’s provincial special­ist for insect pest management. Specifically, eastern Sask­­­­atch­ewan, primarily east central and southeast. There’s another section from Prince Albert south, “extending quite a ways, at least down to close to Bethune.” Midge threats in Alberta aren’t as high, but are more pronounced east of Edmonton and in the Peace region. However, Alberta […] Read more
