Metarhizium anisopliae and Beauveria bassiana are ubiquitous insect pathogens and possible plant symbionts, as some strains are endophytic or colonize the rhizosphere. We evaluated 11 strains of M. anisopliae and B. bassiana, and two soil saprophytes (the non-rhizospheric Aspergillus niger and the rhizosphere-competent Trichoderma harzianum) for their ability to germinate in bean root exudates ...

The anamorph genus Metarhizium is composed of arthropod pathogens, several with broad geographic and host ranges. Members of the genus, including "M. anisopliae var. frigidum" nomen nudum and Metarhizium flavoviride, have been used as biological insecticides. In a recent revision of the genus the variety "M. anisopliae var. frigidum" was suggested to be a synonym of M. flavoviride based largely...

PURPOSE To report a case of fungal keratitis caused by Metarhizium anisopliae complex. METHODS Case report. RESULTS Our patient presented with a central corneal infiltrate. Fungal culture yielded a Metarhizium species. She was started on antifungal agents with no significant improvement. A therapeutic corneal transplant was performed after perforation. At two years follow up, she was free o...

Compatibility of the entomopathogenic fungus, Metarhizium anisopliae with representative pesticides, plant oils and a fungal antagonist were studied in vitro. The pesticides tested were: endosulfan, acephate, abamectin, ethion, chlorothalonil, iprodion + carbendazim, thiophanate methyl and dinocap, an antagonist, Trichoderma harzianum and the plant oils: coconut oil, groundnut oil, gingili oil,...

A series of laboratory bioassays were conducted for the evaluation of the insecticidal efficacy of an isolate of Metarhizium anisopliae (Metschnikoff) Sorokin (Ascomycota: Hypocreales) against larvae of the Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), under various temperature-relative humidity (r.h.) conditions. The fungus was applied at four doses (0, 8 × 106...

The red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) is a serious pest of the palm tree in tropical regions of the world. One strain of Metarhizium sp. ZJ-1, isolated from Chinese soils, was evaluated for growth characteristics, and screened for its virulence to R. ferrugineus larvae in laboratory conditions. An approximately 685-bp fragment was amplified by ITS (I...

BACKGROUND Considering to the high distribution of cockroaches as urban pests, the efficacy of different formulations of Metarhizium anisopliae strain Iran 437C were assessed against the brown-banded cockroach, Supella longipalpa F. under laboratory and field conditions. METHODS Metarhizium anisopliae isolates were screened with immersing adults of the brown-banded cockroachs in aqueous suspe...
