OPTIONS forcodling mothCONTROL

摘要

Three years of research found little difference between hand-applied and canister-released pheromone dispensers for disrupting codling moth mating. Aerosol pheromone dispensers worked as well or better than hand-applied mating disruption dispensers insuppressing codling moth, according to Washington State University research."Growers have more robust options today in controlling codling moth than in the past," said Dr. Jay Brunner, WSU entomologist who compared aerosol pheromone dispensers, also called puffers, to hand-applied dispensers. The first pheromone dispenser for codling moth, Isomate C, was registered in 1991. The revolutionary pest control method allowed tree fruit growers to significandy reduce codling moth pesticide application. The technique, which works by inundating an orchard with female pheromone to confuse male moths, has been widely adopted by Pacific Northwest apple growers. Brunner estimated that 90 percent of Washington's apple acreage is treated with pheromone mating disruption.
