The aim of this study is to investigate the chemical content of mesquite (prosopis juliflora) stalk, and the potential use in manufacture of sustainable fiber reinforced polymer composite, papermaking, plastics and textile industry. The raw mesquite stalk has 69% cellulose, 8% hemicelluloses, 0.53% lignin and 11.19% moisture content. The proportion of minerals in the samples were estimated by Inductively Coupled Plasma Emission (ICPE) spectrometer, the minerals in μg/L were, and Ba concentration is less than μg/L. The production of vegetable fibers from the prosopis juliflora stalk was done through chemical extraction and water treatment. The produced fibers have 67% Cellulose, 5.47% lignin, 7.20% hemicelluloses and 0.09% ash. The fibers characterized by Fourier Transform infrared spectroscopy (FTIR), Density, porosity and Tensile strength. The density of the fiber was 0.50 g/cm3 and porosity 0.671. The FTIR spectrum show peaks at 3423.76, 2920.32, 781.20 and 1425.44 cm-1, attributed to O-H stretching, C-H stretching, C-O stretching and deformation vibrations of CH2 and CH groups respectively. The Tensile strength for three samples and elongation for each sample, were 1.09 kg, 3.76 kg , 1 kg, and elongation 1.09% , 1.03% , 0.56% respectively. The Morphological investigation was carried out using scanning electron microscope (SEM) and identifying elements zoom in 20 μm. By analyzing cross section of the sample, it was found to contain 80.6% oxygen and 19.4% calcium.

Due to a lack of knowledge about arthropod biodiversity in Egyptian organic agro-ecosystems; the study aimed to introduce information on the diversity, richness, and distribution of insect and mite species in two organic agro-ecosystems, also, to investigate the impact of plant-arthropod interactions. Samples collected from two organic farms, i) Shampoliah farm, Fayoum (GCS 29°21'07.4"N 30°44'17.8"E), and ii) SEKEM farm, Sharkia (GCS 18 30°22'56.1"N 31°39'17.4"E). Results shown 39 species recorded in Shampoliah farm, and 35 species in SEKEM of mite, insect, medicinal, and weed species. When 14 species shared among two sites. Study has measured the H', D and 1/D indices within each location, and the similarity/dissimilarity between locations. The study hypothesized the possible plant-arthropod interactions that explain why diversity differs from an ecosystem to another; due to; plant size, plant morphological characters, soil fertilization, plant nutritional content, and the prey-predator interactions. The added hypothesis; is to show that the importance of natural habitat is supporting natural enemies and distribution of arthropods, which could vary dramatically with the type of pest species, IPM, and landscape type considered.
