In the present study, pathogenicity of four native strains of Entomopathogenic fungus; Metarhizium anisopliae, was studied against adult stage of Ixodes ricinus. For this purpose a total number of 180 adult ticks were examined in triplicate. Thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. Samples were incubated in separate Pet...

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 Dengue is the most prevalent arboviral disease transmitted by Aedes aegypti worldwide, whose chemical control is difficult, expensive, and of inconsistent efficacy. Releases of Metarhizium anisopliae--exposed Ae. aegypti males to disseminate conidia among female mosquitoes by mating represents a promising biological control approach against this important vector. A better understandi...

چکیده کشاورزی پایدار یک فرایند زیستی است که سعی در پیاده سازی خصوصیات کلیدی یک اکوسیستم طبیعی دارد. در این پژوهش هدف تقویت و افزایش دراز مدت حاصلخیزی خاک، کنترل زیستی آفات و کاهش یا حذف کودهای شیمیایی است. در این راستا آزمایشی در رابطه با تاثیر سطوح 0، 3 و 6 تن در هکتار ورمی کمپوست روی برخی خصوصیات کمی دو رقم گوجه فرنگی و همچنین تاثیر قارچ بیماری‎زای حشرات metarhizium anisopliae بر کاهش خسارت ...

قارچهای بیمارگر حشرات ممکن است به وسیله آفت­کش­های شیمیایی که برای مبارزه با آفات استفاده می­شوند، تحت تاثیر قرار گیرند. سازگاری قارچ­های Beauveria bassiana  و Metarhizium anisopliae با سه قارچ­کش و 16 حشره‌کش در آزمایشگاه مورد ارزیابی قرار گرفت. آفت­کش­ها در سه غلظت (غلظت میانگین، نصف و دو برابر غلظت میانگین) آزمایش شدند. نتایج آزمایش‌ها نشان داد که قارچ­کش­های مورد استفاده در هر سه غلظت با ای...
