Abstract
  • BACKGROUND: Oregon produces 99% of the hazelnuts grown in the United States. The key pest threatening commercial hazelnut orchards in Oregon is Cydia latiferreana (Tortricidae), filbertworm moth (FBW). Currently, most growers control FBW with one to two applications of esfenvalerate (Asana XL), a broad spectrum pyrethroid. Pheromone mating disruption is an alternative or accompaniment to pesticides that are used to control related lepidopteran pests. Trials were conducted during 2009 and 2010 in two commercial orchards in the Willamette Valley of Oregon using a synthetic sex 1 pheromone. Dispensers containing components of FBW sex pheromone were placed at two densities(high, low, and untreated control) during 2009 and low density and control during 2010. Traps containing septa of the compound at two strengths (1x and 10x) were placed in each test plot. RESULTS: Greater mean FBW per trap counts were recorded in control plots than in the treatment plots in one orchard in 2009. Greater numbers of FBW were captured in control plots versus treatment plots in all replications. Nuts examined for infestation of FBW were below the industry rejection threshold of 1%. Percent-trap-shutdown rates ranged from 58.2% to 81.7% CONCLUSION: Observed trends in FBW trap counts using mating disruption management method warrant further research.
