The three fungal pathogens Metarhizium anisopliae (Metchnikoff) Sorokin (Hypocreales: Clavicipitaceae), Paecilomyces fumosoroseus (Wize) Brown & Smith (Deuteromycotina: Hyphomycetes), and Beauveria bassiana (Bals.-Criv.) Vuill. (Hypocreales: Clavicipitaceae) were evaluated as potential biological control agents against the cactus moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae). The ...

A promising alternative for insect pest control in agriculture is the use of entomopathogenic fungi. The objectives this work were to isolate and identify morphologically molecularly strains fungi from crops agricultural forestry interest development biocontrol technologies Argentina. Three Beauveria bassiana, two Metarhizium anisopliae isolated identified. Identity values greater than 99% with...

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 exposureunder laboratoryconditions.Results showed thatA.planipennisadultswere susceptible toB. bassiana andM. anisop...

The potential of a dry powder co-formulant, kaolin, to improve the control of storage beetles by the entomopathogenic fungus Beauveria bassiana, isolate IMI389521, was investigated. The response of Oryzaephilus surinamensis adults to the fungus when applied to wheat at 1 × 10(10) conidia per kg with and without kaolin at 1.74 g per kg wheat was assessed. Addition of kaolin increased control fro...

SILVA, S.B. DA; BITTENCOURT V.R.E.P. [Evaluation of cellular response in engorged females of Boophilus microplus (Canestrini, 1887) inoculated with Metarhizium anisopliae, Beauveria bassiana, Penicillium corylophilum or Fusarium oxysporum]. Avaliação da resposta celular de fêmeas ingurgitadas de Boophilus microplus (Canestrini, 1887) inoculadas com Metarhizium anisopliae, Beauveria bassiana, Pe...

Solenopsis invicta Buren is one of the most important pests in China, and control measures are mainly based on the use of synthetic pesticides, which may be inadequate and unsustainable. Hence, there is a growing interest in developing biological control alternatives for managing S. invicta, such as the use of entomopathogenic fungi. To facilitate the commercialization of entomopathogenic fungi...

Beauveria bassiana is a fungal entomopathogen with the ability to colonize plants endophytically. As an endophyte, B. bassiana may play a role in protecting plants from herbivory and disease. This protocol demonstrates two inoculation methods to establish B. bassiana endophytically in the common bean (Phaseolus vulgaris), in preparation for subsequent evaluations of endophytic biological contro...

Declining populations of kudzu bug, Megacopta cribraria (F.), in the southeastern United States have been observed since 2013 and are generally attributed to increased prevalence of natural enemies. Beauveria bassiana (Bals.-Criv.) Vuill. infects kudzu bugs in North America, but the level of pest suppression has not been reported. Beauveria bassiana is sensitive to classes of fungicides used to...

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...

Understanding habitat selection of fungal entomopathogens is critical to improve the efficacy, persistence and cost of these fungi as microbial insecticides. This study sought to determine the prevalence of Metarhizium and Beauveria spp. isolated from the rhizosphere of strawberry, blueberry, grape and Christmas tree crops in the Willamette Valley of Oregon. Entomopathogenic fungi were assigned...
