سازگاری سه حشره‌کش فیپرونیل، پایری‌پروکسی‌فن و هگزافلومورون با جدایه‌ی DEBI 002 (آتشگاه) قارچ Beauveria bassiana مورد بررسی قرار گرفت. برای تعیین اثر این حشره‌کشها روی جوانه‌زنی اسپور قارچ، غلظت‌های مختلف آن‌ها به محیط کشت مالت آگار اضافه شد. به‌منظور محاسبه‌ی میزان رشد میسیلیوم در تیمارهای مختلف، قطر کلنی اندازه‌گیری شد و ارزیابی میزان اسپورزایی با شمارش اسپورها در واحد سطح صورت گرفت. نتایج نش...
the compatibility of beauveria bassiana isolate debi 002 (atashgah) with fipronil, pyriproxyfenand hexaflumuron insecticides was assayed. to determine the impact of the insecticides on thegermination of the fungal spore, different concentrations of the compounds were added to the culturemedium (malt agar). in order to calculate the mycelial growth in different treatments, each colonydiameter wa...
Jujube fruit fly, Carpomyia vesuviana, is the most important pest of jujube in Iran. During February and March 2013, a survey on fungi associated with pupae of C. vesuviana was conducted in Birjand, South Khorasan province of Iran. To isolate fungi, the samples were washed under running tap water, surface-sterilized in 0.5% sodium hypochlorite, then rinsed and placed ...
The exopolysaccharide (EPS) separated from the entomopathogenic fungus Metarhizium anisopliae was determined by gel permeation chromatography to be homogeneous. The high-performance anion-exchange chromatography with pulsed-amperometric detection (HPAE-PAD) showed a content of monosaccharides D-galactosamine and D-fucose at a molar ratio of about 2:1. The results obtained from Fourier transform...
Entomopathogenic fungi produce secondary metabolites which may bioactively help fungus in its virulence toward insect hosts. Beauveria bassiana produces several toxic low molecular compounds in vitro as well as in vivo, the most important of them is Beauvericin. The BEH isolate of the fungus was selected for Beauvericin assay. Beauvericin was obtained from surface and submerged cultures of the ...
