A New Technique

Algeria’s date palm (Phoenix dactylifera L) fruit is one of the most important exported products from non hydrocarbon sources. As other fresh or dry fruits, the dates (cv. Deglet Nour) are exposed to damage during storage. In our study, we will apply a postharvest treatment using a radiofrequency radiation as a new technique used on dates while evaluating its effect on date palm fruit quality. The results obtained reveal that the treatment was effective on the capacity of dates to maintain their pH, moisture content and ash percentage during the storage compared with the dates untreated. Likewise, it achieved complete disinfection of dates. As results, the radiofrequency presents a practical alternative to the actually techniques used on postharvest treatment.

The main objective of this study was to test some technological performances of date palm stem (Phoenix dactylifera L.) from the region of Marrakech in Morocco with a view to its use in housing construction in southern Moroccan regions. Physical characteristics were determined according to French AFNOR standards. The samples used were respectively 20 mm × 20 mm × 20 mm in the longitudinal, radial and tangential directions. All the results obtained were the average of the measurements on 50 samples. The results obtained showed that the moisture content has an average value of 15 % at the center of stem and 18 % at the periphery and the infradensity has a value of 0.18 g / cm3 in the center and 0.42 g / cm3 in the periphery. For samples from the center, the tangential, radial and longitudinal shrinkage were respectively 2.02 %, 1.77 %, and 0.42 %, while on the periphery of the stem the tangential, radial and longitudinal shrinkage were respectively 3.41 %, 2.98 % and 0.34 %. These results showed that the stem center has better dimensional stability compared to the peripheral region of the stem.

Comprehensive Survey

A comprehensive survey was conducted at different provinces of Saudi Arabia (SA) to investigate predacious prostigmatid mites (Acari: Trombidiformes: Prostigmata) mainly collected from the date palm, Phoenix dactylifera L. (Arecaceae) agro-ecosystem. A total of 41 species belonging to 28 genera in 14 families are recorded in the present study. Out of these, three families, 18 genera and 36 species are new to the mite fauna of SA. The new species, Neobonzia tabukensis sp.nov. (Cunaxidae), Cheletomimus (Philippicheyla) taifensis sp.nov. (Cheyletidae) are described and illustrated. A checklist of predatory prostigmatid mites from SA is given. A key to all terrestrial predatory prostigmatid mites, excluding Parasitegona and Heterostigmatina, reported from SA is provided. Also, a key to world species of the subgenus Philippicheyla Corpuz-Raros of the genus Cheletomimus Oudemans is given.
