Progress Report Objectives (from AD-416) Develop the use of ultra low volume spray applications (< 5 gallons per acre) of a microencapsulated sex pheromone formulaltion for codling moth. Approach (from AD-416) Various studies will be conducted to evalaute the deposition and retention of microencapsulated sex pheromone of codling moth when applied with an ATV-pulled low volume sprayer. Efficacy trials will be conducted to compare this approach with standard uses of hand-applied sex pheromone dispensers in grower's orchards. Documents Trust with WA Tree Fruit Research Commission.

Significant Activities that Support Special Target Populations This report serves to document research conducted under a Trust agreement between ARS and Washington Tree Fruit Research Commission. Additional details of research can be found in the report for the parent project 5352-22000-017-00D 'Management of Insect Pests of Temperate Tree Fruit Crops'. Field evaluation of a new dispenser loaded with sex pheromone and pear ester was evaluated in a series of field trials. The new dispenser effectively shut-down traps baited with virgin female moths all season and outperformed a commercial dispenser late in the season. In orchard trials, moth catches were significantly lower in blocks treated with the new dispenser than a commercial dispenser. No difference in fruit injury were found in orchards treated with either dispenser type. The addition of a microencapsulated pear ester formulation effectively reduced codling moth injury when added at rates of 12 � 24 ml/100 gallons to half rates of Imidan. The addition of either Assail or Asana to a ULV pheromone 5- spray program significantly improved the effectiveness of the pheromone alone program. ADODR STATEMENT: Monitoring of activities and progress on this project was accomplished by direct supervision of on site employees, and use of e- mail and telephone to communicate with off site collaborators.

Progress Report 4d Progress report. This report serves to document research conducted under a trust agreement between ARS and the Washington Tree Fruit Research Commission. Additional details of research can be found in the report for the parent CRIS 5352-22000-017-00D Management of Insect Pests of Temperate Tree Fruit Crops Research in commercial orchards evaluated the effectiveness of ultra low volume applications of a microencapsulated sex pheromone for codling moth. Studies in 2006 were all conducted in apple orchards and at mid season. Fruit injury was similar in orchards treated with either the low volume sprays or hand-applied pheromone dispensers. In addition, the use of supplemental ultra low volume insecticide sprays significantly reduced fruit injury versus the untreated check plots.
