در این تحقیق میزان تولید و جوانه زنی اسپور و بلاستوسپورهای قارچ metarhizium anisopliae که روی بذرهای مختلف تولید شده بودند، مورد ارزیابی قرار گرفت. آزمایش ها به صورت فاکتوریل و در قالب طرح کاملاً تصادفی که دارای 9 تیمار در سه تکرار بودند، انجام شد. نتایج اختلاف معنی داری را بین تعداد کنیدی تولید شده، دو هفته پس از کشت نشان داد (f= 4.66, df= 7, 16, p<0.01). بیشترین میانگین تولید محصول به میزان 10...
Metarhizium anisopliae is used as a biopesticide for insects that damage agricultural plantations like sugar cane and forage plants. In a previous study the sensitization to this fungus of asthmatic patients coming from sugar cane areas was showed. The aims of this work were: to compare crude extracts obtained with Tris-HCl and Coca liquid from several growth phases of M. anisopliae concerning ...
BACKGROUND The recent outbreak of bluetongue virus in northern Europe has led to an urgent need to identify control measures for the Culicoides (Diptera: Ceratopogonidae) biting midges that transmit it. Following successful use of the entomopathogenic fungus Metarhizium anisopliae against larval stages of biting midge Culicoides nubeculosus Meigen, we investigated the efficacy of this strain an...
Expressed sequence tag (EST) libraries for Metarhizium anisopliae, the causative agent of green muscardine disease, were developed from the broad host-range pathogen Metarhizium anisopliae sf. anisopliae and the specific grasshopper pathogen, M. anisopliae sf. acridum. Approximately 1,700 5' end sequences from each subspecies were generated from cDNA libraries representing fungi grown under con...
The susceptibility of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) to selected strains of the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin was evaluated through bioassays with direct immersion or foliar exposure under laboratory conditions. Results showed that A. planipennis adults were susceptible to B. bassiana and ...
ازدیاد و بیماریزایی قارچ های بیمارگر حشرات ممکن است تحت تأثیر آفتکش ها قرار گیرند.سازگاری (metarhizium anisopliae s.l. (metschnikoff) sorokin (demi 001 strain با حشره کش ایمیداکلوپرید، با بررسی اثرات آن بر جوانه زنی کنیدی، رشد رویشی کلونی و میزان اسپورزایی، مورد ارزیابی قرار گرفت. محیط کشت قارچ sday با غلظت های 10، 100 و 500 پی پی ام از ایمیداکلوپرید مخلوط شده و محیط عاری از حشره کش به...
Entomopathogenic fungi Metarhizium species are generally employed to manage the soil-dwelling stage of insect pests, and known for their rhizocompetency property. Since this fungus is typically recommended use in soil, it could potentially be investigated as a bioinoculant reduce abiotic stress, such salinity, along with improved plant growth promotion. Salt stress tolerance potential native is...
Filth flies are pests of livestock, and can transmit pathogens that cause disease to animals and their caretakers. Studies have shown successful infection of adult filth flies following exposure to different strains and formulations of entomopathogenic fungi. This study aimed to examine the effects of commercial formulations of Beauveria bassiana (Balsamo) (Moniliales: Moniliaceae) (i.e., Botan...
