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 ...
Microsclerotia (MS), overwintering structures produced by many plant pathogenic fungi, have not been described for Metarhizium anisopliae. Three strains of M. anisopliae--F52, TM109, and MA1200--formed MS in shake flask cultures using media with varying carbon concentrations and carbon-to-nitrogen (C:N) ratios. Under the conditions of this study, all strains produced MS, compact hyphal aggregat...
The pigeon tick Argas reflexus is a pathogen-transmitting soft tick that typically feeds on pigeons, but can also attack humans causing local and systemic reactions. Chemical control is made difficult due to environmental contamination and resistance development. As a result, there is much interest in increasing the role of other strategies like biological control. In this study, the efficacy o...
BACKGROUND Metarhizium is an important class of entomopathogenic fungi in the biocontrol of insects, but its virulence is affected by insect immunity. To clarify the mechanism in virulence of Metarhizium, we compared the immunological differences in Locusta migratoria L. when exposed to two strains of Metarhizium anisopliae (Ma). RESULTS The virulence of Ma IMI330189 was significantly higher ...
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...

سوسک شاخک بلند سارتا Aeolesthes sarta Solsky (Col.: Cerambycidae) یکی از مهمترین آفات چوبخوار در ایران و برخی دیگر از کشورهای آسیا بوده و بهرغم اهمیت آن، مطالعات معدودی دربارهی کنترل بیولوژیک آن انجام شدهاست. در تحقیق حاضر اثر قارچ بیمارگر Metarhizium anisopliae جدایهیDEMI-001 علیه لارو آفت مورد ارزیابی آزمایشگاهی قرار گرفت. برای این منظور غلظتهای مختلفی از کنیدی قارچ تهیه شده و لاروهای آف...
چکیده اثر غلظت های مختلف جدایه EUT115 قارچ Metarhizium anisopliae به همراه شاهد، بر مراحل مختلف رشدی شتهی سبز هلو Myzus persicae، روی سه ژنوتیپگیاه کلزا Brassica napus، در شرایط آزمایشگاهی مورد بررسی قرار گرفت. تعداد 30 شته از هر مرحلهی رشدی با قارچ تیمار و به تشتک های پتری حاوی دیسکهای برگی روی آب- آگار 2 درصد منتقل شد. مرگ و میر شته ها به صورت روزانه تا 14 روز پس از شروع آزمایش ثبت شد. ب...
BACKGROUND Filamentous fungi are the most widely used eukaryotic biocatalysts in industrial and chemical applications. Consequently, there is tremendous interest in methodology that can use the power of genetics to develop strains with improved performance. For example, Metarhizium anisopliae is a broad host range entomopathogenic fungus currently under intensive investigation as a biologically...
