Comparison of Different Pheromone Release Systems for Mating Disruption of the Obliquebanded Leafroller Integrated with a Biorational Insecticide

Abstract

The effectiveness of three different types of pheromone release systems in disrupting OBLR mating and subsequently preventing fruit damage were compared in 5-acre plots in two commercial orchards: (1) Microsprayers (aerosol spray-burst devices, MSU), one application setup for the summer; (2) Microencapsulated sprayable pheromone (3M), two applications applied by the growers per summer generation; and (3) Paraffin-based pheromone emulsions (Agrium), one application per summer generation.
