Abstract
Laboratory-reared male redbanded leafroller moths, Argyotaenia velutinana (Walker), were marked and released into small field plots permeated with a pheromone component (Z)-11-tetradecenyl acetate at a release rate of 5 mg/h/ha. Pheromone-mediated activation occurred normally in released males whether or not they were previously exposed to disruptant before their normal peak of activity. Preflight behaviors such as wing-fanning while walking were followed by flight, but orientation to sex pheromone-baited traps in the plot center was significantly reduced compared to a control plot.
