the beet armyworm spodoptera exigua (hübner) is a serious and economically important pest of solanaceous crops worldwide. the nutritional indices of this pest on three host plants including pepper capsicum frutescens, eggplant solanum melongena and tomato solanum lycopersicum were determined under laboratory conditions at 26 ± 1 °c, 60 ± 5% rh and 16: 8 (l: d) h. the highest relative consumptio...
Objective- The aim of this study was to determine the first possible time for pregnancy recognition and several features of developing embryo between days 8 to 44 of pregnancy. Design- Experimental study Animals- Six healthy registered Caspian mares Procedures- Daily ultrasound examinations were conducted from days 8 to 44 (ovulation = day 0) of pregnancy to monitor the conceptus in Caspian ...
background: this study quantified the effect of four popular culture media in a biodiesel production study on the qualitative and quantitative lipid content, dry biomass, and lipid productivity of nannochloropsis oculata. methods: culture of microalgae was done separately in walne, f/2, sato, and tmrl media. in the logarithmic and stationary growth phases, biomass production and lipid accumulat...
this study evaluated the effects of 0.25% activated charcoal added to sesame seed meal (ssm) in partial replacement of soybean meal (sbm) of juvenile clarias gariepinus diet on growth and haematological parameters for 70 day experimental period. six experimental diets were formulated as: control diet 1 (100% ssm without activated charcoal), control diet 2 (100% ssm plus 0.25% activated charcoal...
A 10-week feeding experiment was conducted to evaluate the effects of feeding level, energy and protein maintenance requirement of rainbow trout, Oncorhynchus mykiss, fingerling (5.65±0.45cm; 1.42 ±0.25g) by feeding casein-gelatin based purified diet (45% CP; 3.67 kcal g-1 GE) at six feeding levels 2-7% of BW/day in two equal meals, at 0800 and 1700 h, in triplicate, with 20 fish per trough fi...
the green colonial microalga, botryococcus braunii is well known for its high lipid content and has already been proposed as a renewable energy source for various aquaculture and biotechnological applications. however, due to its slow growth rate compared with other microalgae, b. braunii has not yet been used in mass culture to produce more biomass. therefore, in this study we tested different...

the present study was conducted to investigate the clinical effects and possible side effects of yarrow extract ( achillea millefolium l.) as feed additive on biochemical blood parameters and growth performance of rainbow trout ( oncorhynchus mykiss ). fishes were treated with 0 (control), 0.1, 0.5 and 1% of yarrow extract for 30 days. plasma alanine aminotransferase (alt), aspartate aminotrans...
The neutron longitudinal and transverse asymmetries A n 1 and A n 2 have been extracted from deep inelas-tic scattering of polarized electrons by a polarized 3 He target at incident energies of 19.42, 22.66 and 25.51 GeV. The measurement allows for the determination of the neutron spin structure functions g n 1 (x; Q 2) and g n 2 (x; Q 2) over the range 0:03 < x < 0:6 at an average Q 2 of 2 (Ge...
the effect of various host plants including chickpea (varieties arman, hashem, azad and binivich), common bean (variety khomein), white kidney bean (variety dehghan), red kidney bean (variety goli), cowpea (variety mashhad), and tomato (variety meshkin) on the reproductive performance and growth indices of the cotton bollworm, helicoverpa armigera (hübner) was determined under laboratory condit...
