Entomopathogenic fungi, such as Metarhizium anisopliae and Beauveria bassiana, are being researched as alternatives to chemical adulticides to control mosquito vectors of malaria and dengue. Two cited concerns of fungal control include conidial viability and risks fungal entomopathogens pose to human health. We measured spore viability of 10 fungal isolates over 26 weeks and found a range of pe...
The variability in esterases of the entomogenous fungus Metarhizium anisopliae was determined electrophoretically on 8.5% polyacrylamide gel. Ten isolates from diverse taxonomic groups of insects were analyzed. The electrophoretic analysis showed differences and similarities between these isolates and it was possible to distinguish six different patterns. The results obtained show a great polym...
Beauveria bassiana (Balsamo) Vuellemin, Metarhizium anisopliae (Metschnikoff) Sorokin and Vertillium lecanii are entomopathogenic fungi (EPF) that occur naturally in the environment and have a potential as biological control agents against many insect pests. A laboratory study was conducted to mass produce entomopathogenic fungus, Beauveria bassiana, Metarhizium anisopliae and Verticillium leca...
The objective of this work was to evaluate if the immunosuppressant Sandimmun Neoral enhances the activity of Metarhizium anisopliae against the leaf-cutting ant Atta sexdens. The vulnerability to the pathogen was measured by comparing the mortality rate of worker ants subjected to the following treatments: immunosuppressant+control, immunosuppressant+M. anisopliae, excipient+control, excipient...
نماتود ریشهگرهی از مهم ترین نماتودهای انگل گیاهی با دامنه وسیع میزبانی است. با توجه به خطرات سموم، استفاده از روش های غیرشیمیایی، از جمله مهار زیستی در مبارزه با آفات و بیماری های گیاهی ضروری به نظر می رسد. در این پژوهش، اثر دو عامل کنترل زیستی metarhizium anisopliae و pseudomonas fluorescens cha0 بر نماتود meloidogyne incognita به طور جداگانه و به طور توام، در چند آزمایش مطالعه گردید. در آزم...
Social life is generally associated with an increased exposure to pathogens and parasites, due to factors such as high population density, frequent physical contact and the use of perennial nest sites. However, sociality also permits the evolution of new collective behavioural defences. Wood ants, Formica paralugubris, commonly bring back pieces of solidified coniferous resin to their nest. Man...
Metarhizium spp. are being used as environmentally friendly alternatives to chemical insecticides, as model systems for studying insect-fungus interactions, and as a resource of genes for biotechnology. We present a comparative analysis of the genome sequences of the broad-spectrum insect pathogen Metarhizium anisopliae and the acridid-specific M. acridum. Whole-genome analyses indicate that th...
Strains of insect-pathogenic fungi with high virulence toward certain pest insects have great potential for commercial biological control applications. Identifying such strains has been a central theme in using fungi for biological control. This theme is supported by a persistent paradigm in insect pathology which suggests that the host insect is the predominant influence on the population gene...
Entomopathogenic ascomycete fungi are ubiquitous in soil and on phylloplanes, and are important natural enemies of many soil-borne arthropods including larval western corn rootworm, Diabrotica virgifera virgifera, which is a major pest of corn. We measured the prevalence of Beauveria bassiana and Metarhizium anisopliae sensu lato in ten cornfields in Iowa, USA by baiting with larval insects. B....
In an initial attempt to characterise single-spore isolates from Metarhizium anisopliae wild-type strain V275, three genetically identical spontaneous pr1A- and pr1B-deficient mutants were detected. These mutants were identified by Nested-PCR amplification and verified by Southern hybridisation. Sequencing and comparison of the highly conserved sequences of 28S rDNA domains 9-11 confirmed that ...
