Interpretive Summary:

Technical Abstract: The navel orange worm, Amyelois transitella (Walker), is a major pest of harvested nuts including walnut, almonds, and pistachios. Nitric oxide (NO) is a potent fumigant with strong efficacy against a wide range of insect pests, including both external and internal feeders. Due to the oxidation of NO, NO fumigation has to be conducted under the ultralow oxygen (ULO) conditions and has to be flushed with inert gas, such as nitrogen gas, at the end of fumigation. In this study, we evaluated the efficacy of NO fumigation against A. transitella at different life stages at 25°C under ULO conditions (
