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.

    The study was conducted on date palm fruit (Phoenix dactylifera L.) c.v. Ashrassi, wich included tow experiment: first one field study carried out during the growing season 2017 at Mandali date palm station/ Ministery of Agriculture, the second one was A laboratory experiment conducted at Post harvest physiology lab at the Department of Horticulture and Landscape Grading/ College Agriculture University of Diyala,9 trees were selected at 10 years old homogeneous in size and growth planted at 5x5 m, The experiment was designed as factorial experiment using Complete Block Designed (RCBD), with two factor: tryptophan spraying at 0, 100, 200 ml. L- 1 concentration five times one spray each month, at Hababok stage, the second factor: some artificial ripening method to promote fruit Ripening, included (heat treatment at 20ºC for 10 minutes, freezing the fruit at- 18 ºC for 42 hours, and soaking the fruit in ethephon solution at 1000, 1500 ml. L- 1. The results can summarized as follow, The interaction between tryptophan spray with 200 ml. L- 1 and freezing the fruit gave the highest values for fruit weight, length and total sugar percent, also the interaction between tryptophan spray with 200 ml. L- 1 and soaking the fruit in ethephon solution at 1500ml.L- 1 resulted significant increase in reducing sugar percent.

Phoenix Dactylifera L

In this study, long term preservation of butter oil was achieved through ethanolic extract of date palm fruit (Phoenix dactylifera L.). Butter oil was supplemented with date palm fruit extract (DPFE) at three different concentrations i.e. 250, 500 and 750 ppm (T1, T2 and T3) and compared with a control. Total phenolic content, DPPH free radical scavenging activity and inhibition of linoleic acid peroxidation of the DPFE was 5.19 GAE, 74.2 and 81%, respectively. IC50 value of date extract for the inhibition of DPPH and linoleic acid peroxidation was 2.45 and 0.82 mg/mL, respectively. The loss of oleic acid and linoleic acid in control after six months of storage was 16 and 52% as compared to T3 which was 4% and 14%. T3 yielded the lowest concentration of primary and secondary oxidation products with no effect on sensory attributes. DPFE can be used to enhance the shelf life of  butter oil at ambient temperature.
