Producers urged to protect beneficial insects

When battling crop pests, a research scientist cautions farmers not to throw the baby out with the bathwater

Prairie crop producers need to focus on conserving beneficial insects while simultaneously managing pest insects. Many of those beneficials help promote synergies and make the best use of other ecosystem service providers.

Bless your mess: Crops may not be best for underperforming acres

Taking poorer-producing ‘messy’ landscapes out of crops may improve fields’ economics and farms’ sustainability

UPDATED, March 7 — It might be difficult to consider “messy” fields as a pathway to improved crop production and profitability. But in the early going, a Prairie-wide university-developed research project suggests taking poor-producing acres out of annual crop production might be a means of improving overall efficiency, as well as the all-important bottom line.

An entomologist with the University of Manitoba stresses that farmers can be proactive in protecting predator and parasitoid populations.

Predators and parasitoids – your bug buddies in the field

How to spot and protect beneficial bugs in your crops

When scouting for insects in your fields next year, it’s not only crop-devouring pests you should keep an eye out for. That’s because insect predators like ground beetles as well as parasitic wasps and flies can take a big chunk out of pest populations. “It’s important to recognize there are a lot of natural enemies […] Read more

Saskatchewan producer Stuart Lawrence minimizes his insecticide use by letting lady beetles, a natural enemy of his problem aphids, do as much of the work as possible.

Beneficial insects play key roles on Prairie farms

The benefits of beneficials are many and varied, some parasitize or feed on crop pests while others can pollinate crops and improve seed set

A growing number of crop producers are recognizing the role of beneficial insects on their farms. It seems like just about every crop pest has a natural enemy that can keep their populations at bay, while many crops have beneficials that aid their growth and sustainability. Stuart Lawrence, Dean Hubbard and Ian Steppler are three […] Read more


The red turnip beetle is a pest that feeds on cruciferous crops such as canola or mustard.

Separating the good insects from the bad

These two insects look similar, but only one is beneficial in your fields


Throughout the growing season growers are tasked with the need to tell the difference between many “good” and “bad” things in the field. Sometimes it is hard to quickly tell the difference. Knowing the difference between things in the field is critical to determine if, when, and how to treat. Take for example the red […] Read more

I could see lots of the worms crawling around next to an armyworm that I also observed on the plant.

Crop advisor casebook: Can you identify the worms in this barley?

A Crop Advisor's Solution from the January 7, 2020 issue of Grainews

Like most farmers, Tom has dealt with his share of insect pests. He’s encountered many different pests at his 6,000-acre mixed grain operation near Wadena, Sask., over the years, but this past August he came across a new insect that had him stumped. Tom called me in early August to say he’d been out inspecting […] Read more
