Male Redbanded Leafroller Moth 1 Orientation Disruption in Vineyards 2

Abstract
Male redbanded leafroller moth, Argyrotaenia velutinana (Walker), orientation to pheromone traps was 99% disrupted with a 50:50 blend of ( Z )-11-tetradecenyl acetate and ( E )-11-tetradecenyl acetate released at a rate of 15 mg/h/ha from hollow fibers. Fibers placed on the ground beneath each vine were not as effective as those hung near the top of the vine. A 3rd pheromone component, dodecyl acetate, which elicits A. velutinana close-range mating behavior, was neither effective in disrupting male orientation to pheromone traps by itself nor in combination with the other 2 chemicals when released from microencapsulated formulations.
