“…The fumigated dates were found to be phosphine residue-free. In addition, no changes in organoleptic properties were noted, which is consistent with earlier results published in previous studies [8][9][10]. The plate formula provided a maximal phosphine concentration much earlier and faster than phostoxin tablet formula.…”

Stored product insect pests, mainly sap beetles and moths, attack dates during the storage period. Currently, after methyl bromide phases-out, phosphine fumigation, heat treatment, and modified atmosphere are used for date disinfestation. Each of these methods has advantages but also serious limitations. To improve phosphine fumigation for date disinfestation, FumBox® -a mobile fumigation container -was designed and tested in commercial conditions. The FumBox® , modified dry 40 ft. HC standard container (76.4 m 3 ), was equipped with a newly developed platform generating and constantly monitoring phosphine gas concentrations, air temperature and relative air humidity of the fumigated goods. Magtoxin® Plates 56 % and Phos-toxin® Tablets 56 % (Detia Freyberg GmbH, Germany) were used. Dates of Medjool variety were treated. The phosphine was used at a dosage range of 1-3 g/m 3 and the exposure time between 24-72 hrs. Total date disinfestation was achieved in all fumigation treatments. The use of Magtoxin Plates with the D.G. provided more effective, quicker, and safer date disinfestation compared to Phostoxin tablets. The fumigated dates were phosphine residue-free. No changes in organoleptic properties were noted.

“…The efficacy of phosphine for date disinfestation was demonstrated in previous research studies [4][5][6][7][8]. Our current experiments, which used and incorporated the newly designed mobile fumigation container FumBox ® and P.G., demonstrated that Magtoxin Plates 2 g/m 3 for 24 hrs resulted in the best date disinfestation outcome.…”

In this concluding article in the series on the technological feasibility of ionizing radiation treatment for shelf life improvement of fruits and vegetables, the present status of research on several commodities that have not been dealt with earlier is discussed. The commodities include mushrooms, tomatoes, pineapples, lychees, longans, rambutans, mangostenes, guavas, sapotas, loquats, ber, soursops, passion fruits, persimmons, figs, melons, cucumbers, aubergines, globe artichokes, endives, lettuce, ginger, carrots, beet roots, turnips, olives, dates, chestnuts, almonds, pistachios, and other dried fruits and nuts. Changes induced by irradiation on metabolism, chemical constituents, and organoleptic qualities are considered while evaluating the shelf life. The commodities have been grouped into those showing potential benefits and those not showing any clear advantages from radiation treatment. Shelf life improvement of mushrooms and insect disinfestation in dried fruits, nuts, and certain fresh fruits appears to have immediate potential for commercial application.

There is a need for alternative treatments for postharvest pests on stored products. In this study, 45-d long-term controlled atmosphere (CA) treatments with 3, 5, 6.5, and 8% O2 were studied to determine effects on survival and development of rice weevil (Sitophilus oryzae) and confused flour beetle (Tribolium confusum) eggs and susceptibility of different life stages to a 14-d 5% O2 treatment. Low oxygen treatments were effective against S. oryzae and T. confusum. The 45-d CA treatments with 6.5, 5, and 3% O2 resulted in 0.26, 0.004, and 0% survival rates from egg to adult respectively for S. oryzae and 6.51, 0.14, and 0% survival rates from egg to later stages respectively for T. confusum. For both species, eggs were more susceptible to low oxygen treatment than larvae or pupae. A 14-d CA treatment with 5% O2 resulted in 4.9 and 3.3% survival of eggs of S. oryzae and T. confusum, respectively, as compared with over 50% survival of larvae and pupae for both species. S. oryzae adults, however, were very susceptible to low oxygen treatment and 14-d exposure to 5% O2 atmosphere resulted in zero survival. In contrast, the 14-d exposure to 5% O2 atmosphere resulted in over 94% survival for T. confusum adults. This study suggested there were considerable differences between stored product insects in susceptibility to low oxygen treatment and that long-term CA storage treatments with a low oxygen level of ≤6.5 and ≤5% have potential in controlling S. oryzae and T. confusum, respectively.
