Research Project: Enhancing Biological Control to Stabilize Western Orchard IPM Systems Project Number: 5352-22430-001-13
Project Type: Reimbursable

Start Date: Sep 01, 2008
End Date: Jul 31, 2013

Objective:
The overall objective is to improve the sustainability of apple, pear, and walnut cropping systems in the western U.S., by developing knowledge and tools that would allow growers to take full advantage of biological control in their orchards.

Approach:
• Objective 1: Evaluate the sublethal effects of newer pesticides on key natural enemies in laboratory assays, and in apple, pear, and walnut orchards • Objective 2: Characterize the phenology of key natural enemies using banding studies in the fall and orchard sampling during the spring and summer • Objective 3: Evaluate semiochemicals as a method of monitoring natural enemy presence, abundance, and phenology; assess effectiveness of this tool in evaluating the effects of inseticides on natural enemies; and compare sampling efficacy of these products to results of sampling done using beating trays • Objective 4: Develop methods in gut contents analysis to monitor predation of codling moth by generalist natural enemies, and confirm gut contents results using video monitoring.
