Lygus Bugs in Faba Beans
August 31, 2017
Lygus bugs are known for attacking canola, alfalfa and sunflowers (you can probably blame the lygus for that gross seed), but they can also be a significant pest in faba beans — especially after their canola food source is harvested.
“Similar to other crops, the lygus bug will pierce the faba bean when the seed is still soft. They will also pierce the flowers and the pods,” explains Héctor Cárcamo, entomologist with Agriculture and Agri-Food Canada in Lethbridge. “So they feed on the reproductive structures: the flowers, the pods, and the seeds.”
