BACKGROUND Entomopathogenic fungi such as Beauveria bassiana are considered promising biological control agents for a variety of arthropod pests. Beauveria species, however, have the potential to elicit allergenic reactions in humans, although no specific allergens have been characterized to date. METHODS Four putative allergens were identified within B. bassiana expressed sequence tag (EST) ...

Beauveria is a globally distributed genus of soil-borne entomopathogenic hyphomycetes of interest as a model system for the study of entomopathogenesis and the biological control of pest insects. Species recognition in Beauveria is difficult due to a lack of taxonomically informative morphology. This has impeded assessment of species diversity in this genus and investigation of their natural hi...

The aerobiology of caves in Southern Spain possesses special characteristics, different from located Northern Spain. Previous studies demonstrated the influence outdoor air on north and existence two patterns, depending season. In summer there is an abundance Ascomycota, whereas winter Basidiomycota predominates, which are related to periods stagnation ventilation, respectively. presence airbor...

Six Beauveria bassiana (Balsamo) Vuillemin isolates were obtained from Reticulitermes flavipes (Kollar) and Coptotermes formosanus Shiraki in the U.S. and China. These isolates, plus the B. bassiana isolate 26037 from American Type Culture Collection that was isolated from Colorado potato beetle (Leptinotarsa decemlineata (Say)) were compared against C. formosanus and R. flavipes in the laborat...

An autoinoculative device was used to test the ability of sap beetles (Coleoptera: Nitidulidae) to carry a specific strain of Beauveria bassiana (Balsamo) Vuillemin to overwintering sites in a multiyear field study. The device was baited with the pheromone and coattractants for the dusky sap beetle (Carpophilus lugubris Murray) and placed in the field in the fall of each year. The introduced st...

BACKGROUND: Beauveria bassiana is an important entomopathogenic fungus currently under development as a bio-control agent for a variety of insect pests. Although reported to be non-toxic to vertebrates, the potential allergenicity of Beauveria species has not been widely studied. METHODS: IgE-reactivity studies were performed using sera from patients displaying mould hypersensitivity by immunob...

Beauveria bassiana, an entomopathogenic fungus, is the alternative biocontrol agent exploited against major economic crop pests. Pieris brassicae L. is an emerging pest of the Brassicaceae family. Therefore, in the present study, fungal isolates of Beauveria bassiana, viz. MTCC 2028, MTCC 4495, MTCC 6291, and NBAII-11, were evaluated for their virulence against third instar larvae of P. brassic...

Emerald ash borer (EAB), Agrilus planipennis Fairmaire, native to Asia, is killing ash trees (Fraxinus spp.) across 15 states and southeastern Canada. Integrated pest management using biological control is the only viable long-term approach for controlling the spread of EAB outside of host resistance. Three hymenopteran parasitoids, Spathius agrili Yang, Tetrastichus planipennisi Yang, and Oobi...

Beauveria spp. (one Beauveria sp., two B. brongniartii, and 47 B. bassiana) isolated from insects and soil from Kenya and other 16 different countries, were obtained from the CABI Bioscience Genetic Resource Collection. DNA was extracted from the 50 isolates and their genetic variability was investigated using restriction analysis of the internal-transcribed-spacer ribosomal region restriction ...
