Differential expression of genes involved in entomopathogenicity of the fungi Metarhizium anisopliae var. anisopliae and M. anisopliae var. acridum (Clavicipitaceae).
Expression analysis of the genes involved in germination, conidiogenisis and pathogenesis of Metarhizium anisopliae during its saprophytic and pathogenic life stages can help plan strategies to increase its efficacy as a biological control agent. We quantified relative expression levels of the nitrogen response regulator gene (nrr1) and a G-protein regulator of genes involved in conidiogenesis ...

ملخ کوهان‌دار تاغ یکی از آفات مهم در اکثر تاغکاریهای ایران، به خصوص تاغزارهای استانهای اصفهان، سمنان، تهران (ابردژ ورامین) و خراسان می باشد. این بررسی برای ارزیابی چند حشره کش روی ملخ فوق طی دو سال در قالب طرح بلوکهای کامل تصادفی با سه تیمار و سه تکرار در تاغزارهای شهرستان اردستان انجام گرفت. تیمارها شامل مواد شبه هورمونی دیفلوبنزرون (به صورت دو فرمولاسیون پودری و روغنی)، نومولت و آب به عنوان ش...
full textEffects of temperature and relative humidity on sporulation of Metarhizium anisopliae var. acridum in mycosed cadavers of Schistocerca gregaria.
The effects of relative humidity (RH) and temperature on the sporulation of Metarhizium anisopliae var. acridum on mycosed cadavers of desert locust, Schistocerca gregaria, were assessed in the laboratory. Quantitative assessments of conidial production over 10 days under constant conditions showed that sporulation was optimized at RH > 96% and at temperatures between 20 and 30 degrees C. Under...
full textAdult survival, maturation, and reproduction of the desert locust Schistocerca gregaria infected with the fungus Metarhizium anisopliae var acridum.
Studies were conducted with two different doses of Metarhizium anisopliae var acridum to examine the effects on survival and reproductive potential of adult Schistocerca gregaria under conditions that either limited thermoregulation or enabled optimal thermoregulation. Adult S. gregaria infected with the fungal pathogen showed either a rapid and high mortality at relatively constant temperature...

full textDifferential expression of the pr1A gene in Metarhizium anisopliae and Metarhizium acridum across different culture conditions and during pathogenesis
The entomopathogenic fungi of the genus Metarhizium have several subtilisin-like proteases that are involved in pathogenesis and these have been used to investigate genes that are differentially expressed in response to different growth conditions. The identification and characterization of these proteases can provide insight into how the fungus is capable of infecting a wide variety of insects...
