Background & Aim: The use of herbal extracts as safe and effective factors for eradicating of stores pests has attracted much attention. In this paper, the bio-effects of fumigation and repellent effects of essential oil of Eucalyptus globolus were investigated on red flour beetle. Experimental: In this study, the toxicity, fumigation and repellency contacts were assayed by topical ap...

Current procedures for introduction of DNA into Drosophila embryos require the time-consuming microinjection of DNA solution into individual embryos (1, 2). A procedure has recently been used successfully in plants, yeast and cultured cells for the ballistic introduction of DNA via tungsten (W) particles (3-5) . Using a modification of this procedure for Drosophila embryos, we have obtained tra...
The development of a simple yet greener microfluidic paper-based analytical device (μ-PAD) for on-site detection Mn(II) in various types waters using tannin as natural reagent was described. μ-PAD consists twelve zones, created on Whatman Number 1 filter paper by drawing technique an acrylic watercolor. based the color change reaction zone due to between and pre-deposited tannin. image captured...
The extraction of DNA for molecular analyses is often a limiting factor in terms of cost, time, and availability of skilled labor. Here the authors describe a simple extraction protocol for obtaining DNA from field and greenhouse grown plants. This method was optimized for sampling mature wild sorghum populations in remote areas of Ethiopia and young greenhouse grown seedlings for genetic studi...
ABSTRACT Background and Objectives: Cellulose is a major component of plant biomass, which can be converted into biofuels and valuable chemicals. The key step in utilization of this organic material is its hydrolysis into soluble sugars. This study evaluated cellulase production by Trichoderma harzianum under different pH values, temperatures and incubation...
Trichoderma species have been famous for production of cellulases with relatively high enzymatic activity. However, attempts to use their cellulolytic enzymes in the bioconversion of cellulosic wastes have not been successful because of high cost of production and low enzymatic yields. This study aimed to obtain gamma-induced mutants of T. viride with enhanced extracellular cellulase production...
