The idea under study here is simple: plant something even more attractive than faba beans along the field edge, draw lygus in and hit them with an insecticide before they move on.

Could trap crops help fend off lygus in faba beans?
A study explores how bracketing crops such as safflower or sunflower could help manage lygus in faba fields
What insect pests are bugging your forage crops?
Grasshoppers, cutworms and armyworms can cause major damage if left unchecked. Learn how to scout and manage them
Manitoba Agriculture entomologist John Gavloski highlights several key insect pests that can affect forage crop production and shares strategies for managing them.
When a pest isn’t a pest
Finding flea beetles and lygus bugs in canola fields doesn’t necessarily mean they’re a problem. Sometimes lygus bugs can even benefit the crop
Insect pests aren’t always true pests. Hard as it may be for farmers to imagine, sometimes the insects do more good than harm. That was a key message from an April online seminar on insect control in canola organized by the University of Manitoba’s Faculty of Agricultural and Food Sciences. The three panelists — Alejandro […] Read more
Prairie insect pest outlook for 2023
Grasshoppers top the threat list but flea beetles, wheat midge, lygus bug, cutworms, bertha army worm and wheat stem sawfly are also risks in some areas
The Prairie Pest Monitoring Network (PPMN) warns grasshoppers could be a problem for producers in Manitoba, Saskatchewan and Alberta if hot, dry conditions during the growing season persist into 2023. The network’s annual grasshopper survey is conducted in late summer and early fall by estimating the density of adult insects, usually in ditches along cereal […] Read more
Insect economic thresholds: what do they mean?
Q & A with CPS
Q: What do insect economic thresholds mean? A: Insects can eat into your profits. They can appear at any time during the growing season and can cause damage that is patchy, scattered and difficult to gauge. Accurate estimation of both pest population and potential crop damage levels can only be obtained by thorough field scouting. […] Read more
Lygus bug: Profile of a crop pest
The lygus bug is an interesting pest. Native to Canada, adult insects overwinter under plant debris and migrate into crops, including canola, alfalfa, soybeans and sunflowers. Arriving in spring and summer, they lay their eggs on crop stems. Lygus is a complex that refers to four species: L. elisus (pale legume bug), L. lineolaris (tarnished […] Read more
Lygus bugs: know when to spray them
Researchers are revisiting economic threshold recommendations on spraying these bugs
[UPDATED: Jan. 31, 2018] Economic thresholds are developed and publicized so farmers will know when it makes sense to spray for a particular pest. For example, the economic threshold might be that if you have two bugs in your sweep net, the yield you gain will make it worth your costs and time to spray […] Read more
Watch for lygus bug damage on faba beans
The insects leave a black spot which is discounted by export customers
Central Alberta farmers planning to sell low-tannin faba beans for export will need to beware of lower tolerance levels for lygus bug damage. Snowbird is a low-tannin variety of faba beans commonly sold into the human market overseas. Parkland Alberta Commodities, a grain buyer based in Innisfail, Alberta, set the tolerance level for lygus bug-damaged […] Read more
How to find lygus bugs
Lygus bugs can cause extensive crop damage. Scout for them in your canola crops
In recent years, high populations of lygus bugs have been reported in a large portion of Alberta, as well as in some fields in Saskatchewan and Manitoba. While lygus bugs are always present in canola fields, outbreaks of high populations can cause extensive crop damage. For the most part, canola can compensate for much of […] Read more
