The phylogenetic lineage, taxonomic affiliation and interrelationships of important asexual entomopathogenic fungal genera were studied using the sequences of partial regions of beta-tubulin and rRNA genes. The species structures of Beauveria bassiana and Nomuraea rileyi were also investigated. A total of 147 fungal entries covering 94 species were analysed. Phylogenetic analysis placed all the...

The ascomycete fungus Beauveria bassiana is a pathogen of hundreds of insect species and is commercially produced as an environmentally friendly mycoinsecticide. We sequenced the genome of B. bassiana and a phylogenomic analysis confirmed that ascomycete entomopathogenicity is polyphyletic, but also revealed convergent evolution to insect pathogenicity. We also found many species-specific virul...

de la polimerasa (PCR) y secuenciación mediante amplificación genómica de la región espaciadora interna transcrita (ITS-2) del ADN ribosómico, obteniendo Beauveria bassiana con un porcen-taje de similitud de la misma especie en GenBank del 99% (BLAST GU373855.1). Tras su identificación, y aun no habiendo suficientes pruebas que demostraran la infección fúngica, se decidió tratar al paciente con...

A specimen of Beauveria bassiana was collected from Yang-yang of Gangwon province, Korea in October 2006. Conidial isolates were prepared from the specimen by the dilution method and inoculated in brown rice medium for fruiting body production. After nearly two months incubation for perithecial stromata developed from single isolates as well as from their combinations. They were determined as C...

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....

Fifty Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales) strains isolated from the coffee berry borer were used to develop a novel screening method aimed at selecting strains with the highest biocontrol potential. The screening method is based on percent insect mortality, average survival time, mortality distribution, percent spore germination, fungal life cycle duration, and spor...

Bing, L.A. and Lewis, L.C., 1993. Occurrence of the entomopathogen Beauveria bassiana (Balsamo) Vuillemin in different tillage regimes and in Zea mays L. and virulence towards Ostrinia nubilalis (Hiibner) Agric. Ecosystems Environ., 45: 147-156. The entomopathogen, Beauveria bassiana (Balsamo) Vuillemin, is an important component in the corn (Zea mays L. ) agroecosystem; this pathogen was found...

In this study, the effects of strain Beauveria bassiana (LPSC 1067) as an endophyte in corn plants on consumption, fecundity, and food preference of Dichroplus maculipennis were examined. We observed that the daily consumption by grasshoppers fed with control plants was almost twice that of those that were fed treated plants. Significant differences in fecundity of grasshoppers that were fed wi...

Reports of natural infections of the insect pathogenic fungus Beauveria bassiana (Bals.) Vuill. (Ascomycota: Hypocreales) in greenhouses and laboratory colonies of Scatella tenuicosta Collin (Diptera: Ephydridae), a nuisance pest and vector of plant pathogens, suggest the potential for using B. bassiana for microbial control of this pest. In this study we assessed the diversity of B. bassiana i...

The minisatellite locus, BbMin1, was isolated from a partial Beauveria bassiana genomic library that consisted of poly(GA) flanked inserts. Polymerase chain reaction (PCR) of the BbMin1 repeat demonstrated allele size variation among 95 B. bassiana isolates. Amplification was also observed from single isolates of Beauveria amorpha, Beauveria brongniartii, and Beauveria caledonica. Eight alleles...
