Al-Ayedh: Rearing the Red Date Palm Weevil 353 EVALUATION OF DATE PALM CULTIVARS FOR REARING THE RED DATE PALM WEEVIL, RHYNCHOPHORUS FERRUGINEUS (COLEOPTERA: CURCULIONIDAE)

Development of red date palm weevil Rhynchophorus ferrugineus (Olivier) was evaluated on 4 popular cultivars of date palm, viz., ‘Khalas’, ‘Sukkary’, ‘Khasab’, and ‘Sillaj’ for 2 consecutive generations. The weevils reared on ‘Sukkary’ showed significantly better growth expressed in most parameters such as length, width and weight at larval, pupal and adult stages. Significantly greater numbers...

Palm Date Fibers: Analysis and Enzymatic Hydrolysis

Waste palm dates were subjected to analysis for composition and enzymatic hydrolysis of their flesh fibers. The fruit contained 32% glucose and 30% fructose, while the water-insoluble fibers of its flesh consisted of 49.9% lignin and 20.9% polysaccharides. Water-insoluble fibers were settled to 55% of its initial volume in 12 h. The presence of skin and flesh colloidal fibers results in high vi...
