تاثير نوع بسته بندي و دماهاي مختلف بر ضدعفوني و نگهداري انجير خشك استهبان

Experiments were conducted to evaluate the effects of heat and cold treatments on the disinfestation of dry figs from Estahban. Tow types of packing bags (with or without holes), two storage conditions including one at 23°C and one cold storage condition (10°C and 2°C), 9 heat and cold treatment durations (3, 4, 5, 6, 7, 10, 15, 20 and 25 hrs) and 13 temperature treatments [23, 45, 55, 60, 65, 70, 75, 45+(-25), 50+(-25) and 60+(-25) °C] were used in these experiments. The results showed that Indian meal moth, Plodia interpunctella, which is a major pest in dry fig storage, can be satistfactorily controlled by packing figs in plastic bags with a thickness of 0.24 mm after suitable temperature treatment. Cold storage at 2°C significantly controlled all developmental stages of moths at storage. Temperature treatments at 60°C for 71us or more, at 65°C for 6hrs or more, and at -25°C for 15hrs or more were found to be capable of controling pest most satisfactorily without changing fruit external quality.
