[en] Disinfestation of packed dry dates, Zahdi varity in standard cartons, such as are used in the industry was studied by using gamma radiation or methyl brpmide fumigation. The dose distribution of radiation from gamma beam-650 facility with a Co-60 source was calculated and the best feasible uniforming ratio=1.4 was followed where the average absorbed dose of 15 point was 75.65 Krad. The results of examination indicated that a complete disinfestation was achieved in both methyl bromide and radiation treated boxes when stored for 25 d. The live insects found in the irradiated dates were genetically sterile and developmentally inactive. While on longer periods of storage (55 or 80 d.), live, active and fertile insects have been found in the treated as well as untreated (control) boxes indicating reinfestation cases.(5 tabs., 10 figs., 22 refs.)
