the compatibility of beauveria bassiana isolate debi 002 (atashgah) with fipronil, pyriproxyfenand hexaflumuron insecticides was assayed. to determine the impact of the insecticides on thegermination of the fungal spore, different concentrations of the compounds were added to the culturemedium (malt agar). in order to calculate the mycelial growth in different treatments, each colonydiameter wa...

Chinch bugs of the genus Blissus (Hemiptera: Lygaeidae) are serious pests of maize, wheat, sorghum and various grasses. This study is the first to screen isolates of Beauveria bassiana and Metarhizium anisopliae against 4 instar and adult Blissus antillus aiming to develop a biological control program for this important pasture pest. Ten fungal isolates were initially screened and three isolate...

Factors affecting the occurrence and distribution of entomopathogenic fungi in 244 soil samples collected from natural and cultivated areas in Spain were studied using an integrated approach based on univariate and multivariate analyses. Entomopathogenic fungi were isolated from 175 of the 244 (71.7%) soil samples, with only two species found, Beauveria bassiana and Metarhizium anisopliae. Of t...

A screening test on 29 microorganisms for transformation of xanthohumol led to the selection of twelve fungal strains. One of them, Beauveria bassiana AM278, converted xanthohumol into a glucosylated derivative. This product was identified as xanthohumol 4'-O-beta-D-4'''-methoxyglucopyranoside.

This is the first reported case of native valve endocarditis caused by Engyodontium album. This fungus, rarely seen as a human pathogen, is separated from Tritirachium species by its lack of pigmentation and from Beauveria species by the presence of conidiogenous cells in whorls.

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.

In order to breed a Cordyceps bassiana isolate that stably forms fruiting body in artificial cultivation, isolates derived from subculturing and single spores were tested through mating. From C. bassiana EFCC 783, three subcultured isolates EFCC 2830, EFCC 2831 and EFCC 2832 were obtained and fourteen single conidial isolates were obtained from these three subcultured isolates. Two different mo...
