Vitex pseudo-negundo (Hausskn) were studied on P. . chemical constituents the also assessed using gas chromatography–mass spectrometry. Assays showed that fumigant toxicity A. (LC 50 : 9.60 µl/liter air) was higher than V. 23.05 air). Moreover, speed mortality caused by oil (LT 2.07 h) 3.11 h). To assess oils,...

The development of inexpensive carbon fiber precursors is necessary to meet the future demands fibers. This work shows how asphaltenes, which are obtained as a by-product in bitumen production, can play an important role such precursors. To synthesize fibers from asphaltene, stabilization by means oxidizing acids (HNO3 and H2SO4) was developed. Stabilization could not be achieved non-oxidizing acid (HCl). reactions leading investigated for nitric treatment, led oxidation incorporation...

V2O5-coated, low-cost carbon fibers were produced using asphaltenes and V2O3 as precursors, both industrial byproducts. Asphaltenes can be used without any further treatment to fabricate fibers. The coated with V2O5 a straightforward two-step coating procedure, that is, surface etching of NH4OH, followed by dipping into solution. This facile process represents time-saving alternative other metal oxide techniques, such atomic layer deposition, create fiber-based electrode materials. After...

The cotton bollworm, Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is a polyphagous and cosmopolitan insect pest that causes damage to various plants. In this study, the lethal sublethal effects of azadirachtin Bacillus thuringiensis Berliner sub sp . kurstaki (Bacillales: Bacillaceae) were evaluated on third instar H. under laboratory conditions. LC50 values Bt 12.95 96.8 µg a.i./mL, respectively. A total mortality 56.7% was caused larvae when LC20 insecticides applied in combination...

The Indianmeal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae), is a major stored product pest that found throughout the world. In this study, effect of oral exposure to Bacillus thuringiensis (Berliner) subsp. kurstaki (Bacillales: Bacillaceae) and azadirachtin was evaluated in third instar P. under laboratory conditions. median lethal concentration (LC50) Bt on instars 490 241 μg a.i./ml, respectively. time (LT50) these insecticides same (4.5 d following 750 or 400 a.i./ml...

Habrobracon hebetor Say is one of the most important natural enemies Helicoverpa armigera Hübner (Lep.: Noctuidae).In this study, sublethal effects LC 30 concentration azadirachtin, cypermethrin, methoxyfenozide and pyridalil on functional response H. to different densities 5th instars larvae Ephestia kuehniella Zeller were evaluated.Young females exposed insecticides for an appropriate time exposure.Then, six randomly selected alive transferred individually plastic Petri dishes (10 cm in...

Abstract The Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), is a common pest of cereal grains and other stored products. In this study, the effects ten barley cultivars (Abidar, Bahman, Line20, Line22, Line30, Lisuei, Lokht11, Makuyi, Sahand, Sahraa) were evaluated on life table parameters nutritional indices T. under following laboratory conditions: 33 ± 1°C, 60 5% RH, photoperiod 14: 10 (L: D) h. Life history could be appropriate in resistance susceptibility...

Fumigant toxicity and sublethal effects of essential oils from Artemisia khorassanica Podl. sieberi Bess were investigated against adults Sitotroga cerealella Olivier. To assess the effects, adult moths exposed to LC30 each oil, life table parameters surviving S. studied. Higher fumigant A. (LC50: 7.38 µl/liter air) than 9.26 was observed cerealella. Also, insecticidal (LT50: 9.01 h) faster 14.37 h). A significant extension in developmental time (egg adult) treated with oils. In addition,...

High energy and power values are obtained from fabricated electrochemical double layer supercapacitor (EDLS) cells derived asphaltene precursors, which a solid by‐product of bitumen extraction in pentane solvents. Chemical activation, using dry KOH, is used to activate carbon fibers. activation introduces high specific surface areas (SSAs) into the fiber microstructure by partially etching carbon. The electrodes prepared mixing activated fibers, polytetrafluoroethylene (PTFE), acetylene...
