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...

Date palm, phoenix dactylifera l. (arecales: arecaeae) is the most important crop of the arabian Peninsula. the Kingdom of Saudi arabia is among the top 3 date producing countries of the world estimated to have over 400 date palm cultivars of which 25 are important and yield 1.3 million tons of dates annually. the red palm weevil (RPW) Rhynchophorus ferrugineus (olivier) (Coleoptera: Curculioni...

Genetic Stability of Micropropagated Plantlets in Date Palm

Randomly amplified polymorphic DNA (RAPD) markers were used to analyze genetic stability of the somatic embryogenesis-derived regenerants (R1-6) and mother plant in Iranian date palm (Phoenix dactylifera L.) cultivar Khanizi. Total genomic DNA extracted from in vitro fresh leaves of regenerated plants and mother plant was amplified using 10-mer oligonucleotide Fermantas primers. Four primers of...
