One of the biological controls pest and plant disease is use enophytic bacteria. This study aimed to obtain endophytic bacterial from root tissue shallot plant, which potential as entomopathogens against larvae Spodoptera litura. research was arranged in a completely randomized design (CRD) with nine treatments consisting eight bacteria (isolation tissue) one control three replications. Paramet...
Body composition and fatty acid profile of the body tissue of Caspian kutum (Rutilus frisii kutum) fish larvae were determined from fertilized egg to 50 days post hatching (dph). Feeding with rotifer started from day 3 to day 7 thereafter they were fed with dry food until the end of the experiment. The changes observed in lipid content and the decrease in lipid levels during larval ontogeny ref...

چکیده مورچهها با حمایت از شپشکها در مقابل دشمنان طبیعی، میتوانند برنامههای کنترل بیولوژیک آنها را مختل نمایند. طی سالهای 1389 و 1390 با نمونهبرداری از باغات مرکبات شهرستانهای ساری و بهشهر، فون و فراوانی نسبی مورچههایِ همراه با شپشکها مورد مطالعه قرار گرفت. همچنین، تاثیر تراکمهای مختلف کاست کارگر گونهی santschi lasius turcicus بر میزان تغذیه و فراسنجههای واکنش تابعی حشرات ماده و لا...
In the present study when the egg masses of Lymnaea stagnalis showing different developmental stages were introduced with the sub lethal concentrations of baygon and nuvan from cleavage to before hatching stages exhibited the development arrest in most of the egg capsules due to deviation in protein fractions in the corresponding development stages in comparison to control groups resulted into ...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
Elm leaf beetle, Xanthogaleruca luteola (Müller), life and fertility tables were investigated under laboratory conditions (25±2°C, 70±5%R.H. and 16L: 8D), on Ulmus carpinifolia, U.c.var.umbraculifera, U. glabra var. pendula and Celtis caucasica, in spring and summer. Since the experiments were conducted under controlled conditions, feeding on hosts with different nutritional qualities was consi...

the optimum dosage for field application bactimos (w.p.) was determined as 0.04g/m , when efficacy of four concentration of 0.01 , 0.02 , 0.04 and 0.08 gim2 were compared in 1 x i m2 artificial breeding sites. this dosage caused 69.8%, 55.6% and 43.6% anopheline and 83%, 47.8% and 29.7% culicine larval mortality, in 24.48% and 72 hrs post treatment, respectively. abate and fuel oil were signifi...
background: metarhizium anisopliae strain iran 437c is one of the most virulent fungal isolates against house fly, musca domestica . the objective of this study was to determine the interaction of this isolate with sublethal doses of spinosad against housefly. methods: in adult bioassay, conidia of entomopathogenic fungus were applied as inoculated bait at 10 5 and 10 7 spore per gram and spin...
