The effectiveness of two different types of pheromone release systems in disrupting OBLR mating and subsequently preventing fruit damage were compared in 2.6-5.6-acre blocks in three commercial orchards in western NY: (1) Microsprayers (aerosol spray-burst devices, MSU), one application setup for the summer (Doyle and Oakes orchards); (2) Paraffin-based pheromone emulsions (Agrium), one application per summer generation (Mitchell orchard).
