Technical Abstract: Nitric oxide (NO) has been demonstrated as an effective fumigant against various insect pests on postharvest products under ultralow oxygen (ULO) conditions. NO showed efficacy against all life stages of insect pests with varied fumigation time and temperature, and had feasible cost-effectiveness to be commercially applied for pest control on fresh commodities. In addition, NO fumigation has been demonstrated to enhance the quality of fresh produce quality. In this study, we conducted a series of NO fumigation experiments to control spotted wing drosophila (SWD) Drosophila suzukii (Walker) (Diptera: Drosophilidae), a nuisance insect pest that feeds inside of ripening stone and small fruits, on strawberry under ULO conditions at 2 °C in a growth chamber. Dose-response tests were designed to determine effects of NO concentration (0.5 to 2.5 %) and fumigation time (2 to 8 h) on mortality of SWD at immature life stages (egg, larvae, and pupa). In addition, NO residues were determined using a nitric oxide analyzer to measure nitric oxide, nitrate, and nitrite concentrations in treated and untreated strawberries. The results of the present study are discussed. The likely benefits of NO fumigation on pest control, and quality enhancement of fresh products are also discussed.
