Banded Sunflower Moth Flying

Banded sunflower moth has just started to emerge based on pheromone trapping data from IPM scouts in North Dakota. Sunflower is still in the late vegetative to R1 (terminal bud forms miniature floral head), so it is too early for scouting. Sunflower is susceptible during the flowering period. Banded sunflower moth can be identified by its small size (1/4 inch long), and its forewings with a triangular, dark brown band across the middle of the wing. It is an economic insect pest of oil and confection sunflowers and larvae feed and tunnel through the florets and developing seeds. Oil content of sunflower also can be reduced when moth populations are economic. More on scouting and thresholds in the next issue of Crop & Pest Report.
