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...

Biological control with pathogenic fungi is a promising alternative to chemical control against the subterranean termite. Biological control with pathogenic fungi might provide longlasting insect control without damage to the environment or non-target organisms. M. anisopliae is one of several natural agents for controlling a broad range of insects by direct penetration of the host cuticle. Usi...

We investigated the prevalence of entomopathogenic fungi associated with leaf-cutting ant colonies in a small area of tropical forest in Panama. There was a high abundance of Metarhizium anisopliae var. anisopliae near the colonies. Beauveria bassiana was also detected in the soil, Aspergillus flavus in dump material, and six Camponotus atriceps ants were found infected with Cordyceps sp. Based...

Metarhizium anisopliae is a fungus of considerable metabolic and ecological versatility, being a potent insect pathogen that can also colonize plant roots. The mechanistic details of these interactions are unresolved. We provide evidence that M. anisopliae adheres to insects and plants using two different proteins, MAD1 and MAD2, that are differentially induced in insect hemolymph and plant roo...

Bioassays were conducted to document the effects of Metarhizium anisopliae infection on adult female Asian longhorned beetle (Anoplophora glabripennis) reproduction before death and subsequent survival of offspring. The effect of infection on fecundity was evaluated for females already laying eggs and for newly eclosed females using M. anisopliae isolates ARSEF 7234 and 7711, respectively. Decr...

Ambient pH regulates the expression of virulence genes of Metarhizium anisopliae, but it was unknown if M. anisopliae can regulate ambient pH. Mutants of M. anisopliae altered in production of oxalic acid were evaluated for the interrelationship of ambient pH, buffering capacity added to media, growth, and generation of extracellular proteases and ammonia. Wild-type and acid-overproducing mutan...

Understanding mortality patterns and interactions between entomopathogenic fungi and parasitoids is important to improve insect biological control programs. The aim of this study was to evaluate the effect of Metarhizium anisopliae (Metschnikoff, 1879) Sorokin, 1833 and Beauveria bassiana (Balsamo) Vuillemin, 1912 (Hypocreales: Clavicipitaceae) on adults of Cotesia flavipes (Cameron, 1891) (Hym...
