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.

“…High quality dates should meet grading requirements such as optimal organoleptic hallmarks and the absence of damage or pest residues [9], so postharvest date processing includes disinfestation treatments [10]. Traditionally, prior to storage or packing for sale, dates were disinfested using heat treatments in ovens (60 °C for about 20 min) or by fumigation with methyl bromide or phosphine; more recently, a modified atmosphere with high concentrations of carbon dioxide is being adopted [10,11]. However, these methods all present significant drawbacks, such as possible alterations of organoleptic characteristics due to heat treatments, or health and environmental hazards in the case of fumigation with toxic gases [12].…”

The dried fruit beetle (Carpophilus hemipterus) is considered a key pest of dates, infesting fruits both in the field and during storage. Control measures against the species rely on the use of chemicals or heat treatments based on sunlight, hot air or radio frequency (RF) applications. Previous investigations that have aimed to define control procedures for a total disinfestation using RF treatments with different exposure durations have shown the typical behavior of adults in some trials, which, under the influence of temperature increases, started to escape from infested fruits. We focused on the application of different RF voltage-time combinations to induce the emigration of C. hemipterus adults from dates in order to produce a complete disinfestation. The results showed that the application of 2500 V RF for 8–10 min to infested dates resulted in nearly 100% of adults escaping from fruits, thereby cleaning the commodity with low or no mortality inside and outside the dates. These achievements provide a new strategy for controlling key insect pests of dates that could be applied at an industrial scale, allowing for the quick disinfestation of fruits without affecting the fruit with harmful substances, such as residues from chemical treatments, and without unwanted side effects on date quality.

Modified/controlled atmosphere applications, as an alternative to the chemical treatments, are an effective technique in controlling pest of stored products, especially dried fruits. In gas tight units, it is applied with the principle of preventing the insect respiration by changing the oxygen (O2), carbon dioxide (CO2) and nitrogen (N2) gas levels of the atmosphere. In the study, 1-, 2-and 3-d-old pupae of dried fruit beetle, Carpophilus hemipterus (L.), which is an important dried fruit pest, were exposed to the modified / controlled atmosphere. The modified/controlled atmosphere consisting of 2.1% O2 + 90% CO2 + 7.9% N2 gas mixture was applied for 48, 72, 96 and 120 h at 20°C and 75 ± 5% relative humidity. One, two and three d old pupae responded similarly to modified/controlled atmosphere application. Mortality rates remained close in each exposure time and no significant difference was found between age groups. Unlike the age factor, the exposure time was found to be statistically significant and the mortality rates increased as the exposure time increased in each age group. The highest mortality rates were found as 38, 60 and 47% in 1-, 2-and 3-d old pupae after 120 h of application, respectively.
