Morgan County, Colorado - I thought you may be interested to learn about Sawfly, a pest that has been present in the area we are cutting. The following is a very brief overview.
The adult female deposits eggs in the developing wheat plant. Despite laying many eggs, only one larva will survive. The larva will begin to mature and move down the inside of the stem. Sawfly activity can hamper the metabolic processes of the plant and may reduce yield. The damage to the stem also causes lodging creating harvestability issues. This damage is due to a v-shaped notch larva cut
