The project has a long-term goal to ensure pest-free security and food safety of walnuts in postharvest marketing channels via the development of efficient, economical, and environmentally benign treatments. The short-term goal is to conduct confirmatory trials with Controlled Atmosphere and Temperature Treatments System (CATTS)for control of navel orangworm and codling moth in low-oxygen atmospheres (e.g., 98% carbon dioxide and/or nitrogen) over ~7-8 hours at 43egrees Celsius.
Utilize a cooperative effort between USDA-ARS, USDA-APHIS, California industry, and foreign counterparts to address pest-related barriers to export. Particular attention will be paid to the expansion and retention of export markets for the California Walnut industry. Pests will be targeted with postharvest techniques. outlined as objectives. Conduct commercial-scale studies to confirm treatment efficacy. Whenever possible, treatment parameters will be tailored to infrastructural and logistical requirements of industry with priority given to those that minimize interruption conventional methods of production, storage, and distribution.
