Wheat stem sawfly is a sneaky pest, as the damage caused by the larvae happens inside the cereal plant away from scouting eyes and out of reach of insecticides.
Regardless of the struggle, this little yellow and black insect does require scouting and careful planning for its management as it is a pest on the move.
Dylan Sjolie, who recently completed his Masters degree at the University of Saskatchewan, joins host Shaun Haney for this episode of the Pests & Predators Podcast, to burrow in to the damage wheat stem sawfly causes and the range of management options available for its control.
And that matters, because the pest can cause significant crop damage, most visible as toppled plants that are difficult to harvest. However, the same damage that impacts stem integrity also robs yield and protein content, making this an economically important pest.
There is help in the form of parasitoid wasps that target the sawfly and there are management practices, such as variety selection and harvest cutting height, that can add up to decent management of the pest.
