BACKGROUND The fungal pathogen, Beauveria bassiana, is an efficient biocontrol agent against a variety of agricultural pests. A thorough understanding of the basic principles of insect-fungus interactions may enable the genetic modification of Beauveria bassiana to enhance its virulence. However, the molecular mechanism of insect response to Beauveria bassiana infection is poorly understood, le...

The fungal entomopathogen Beauveria bassiana became established as an endophyte in in vitro-grown cocoa seedlings tested for up to 2 mo after inoculation to the radicle with B. bassiana suspensions. The fungus was recovered in culture from stems, leaves and roots. B. bassiana also was detected as an epiphyte 1 and 2 mo postinoculation. Penicillium oxalicum and five bacterial morphospecies also ...

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...

We describe a case of disseminated Beauveria bassiana infection in a patient with acute lymphoblastic leukemia. Her infection was successfully treated with amphotericin B and itraconazole. B. bassiana is rarely reported as a human pathogen. It is commonly found in soil and because of its pathogenicity to many insect species is incorporated into several pesticides.

A tritrophic association is reported, involving a Colorado potato beetle (Leptinotarsa decemlineata) infected with Beauveria bassiana, which in turn was infected with Syspastospora parasitica.

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...

Background. The New Zealand forest industry would greatly benefit from a successful way of controlling insect pests. The entomopathogenic fungus, Beauveria bassiana could hold such potential and has previously been shown to be capable of endophytic colonisation of the Monterey pine Pinus radiata. Nevertheless clarifications on its mode of transmission, persistence and action in this plant are r...

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...

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...

INTRODUCTION The use of entomopathogenic fungi to control disease vectors has become relevant because traditional chemical control methods have caused damage to the environment and led to the development of resistance among vectors. Thus, this study assessed the pathogenicity of entomopathogenic fungi in Triatoma dimidiata. METHODS Preparations of 108 conidia/ml of Gliocladium virens, Talarom...
