Résumé

Diamond walnuts (Juglans regia) in the shell were treated with radio frequency (RF) energy in a 27-MHZ pilot-scale system to determine the treatment effect on third-instar codling moth, Cydia pomonella (Lepidoptera: Tortricidae) mortality and walnut quality. After 2 and 3 min of RF treatments, infested in-shell walnuts were heated to 43 and 53 °C. The corresponding insect mortality reached 78.6 and 100%. According to the performed tests concerning other parameters (fatty acids, oil peroxide value), it seems that RF treatments can, therefore, potentially provide an effective and rapid quarantine security protocol against codling moth in walnuts as an alternative to methyl bromide fumigation.
