Ten strains of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana were evaluated to find the most effective strain for optimization studies. The first criterion tested for strain selection was the mortality (> 50%) of Spodoptera litura larvae after inoculation of the fungus for 4 days. Results on several bioassays revealed that B. bassiana BNBCRC showed the most virulence ...

In this study, the effects of commercially available entomopathogens, Nibortem (Verticillium lecani), Met52 (Metarhizium anisopliae), Nostalgist (Beauveria bassiana) and Priority (Paecilomyces fumosoroseus), a herbal insecticide, Nimbecidine (Azadirachtin), on pest aphids, Aphis fabae Acyrthosiphon pisum, were investigated. The corrected mortalities they caused to A. 78.41%, 87.50%, 65.91%, 63....

Metarhizium anisopliae is an entomopathogenic fungus that has evolved specialized strategies to infect insect hosts. Here we analyzed secreted proteins related to Dysdercus peruvianus infection. Using shotgun proteomics, abundance changes in 71 proteins were identified after exposure to host cuticle. Among these proteins were classical fungal effectors secreted by pathogens to degrade physical ...

Strains of the entomopathogens Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin were screened for effectiveness against the Formosan subterranean termite, Coptotermes formosanus (Shiraki). Biological control methods are being considered to augment current integrated pest management schemes that involve chemical baits and nonrepellent termiticides. In this...

Western flower thrips (WFT), Frankliniella occidentalis (Pergande), is an important pest of vegetable crops worldwide and has developed resistance to many insecticides. The predatory mites Neoseiulus (=Amblyseius) cucumeris (Oudemans), the entomopathogenic fungus Metarhizium anisopliae (Metsch.), and an insecticide (imidacloprid) were tested for their efficacy to reduce WFT population density a...

Cells store lipids in droplets. Studies addressing how mammals control lipid-based energy homeostasis have implicated proteins of the PAT domain family, such as perilipin that surrounds the lipid droplets. Perilipin knock-out mice are lean and resistant to obesity. Factors that mediate lipid storage in fungi are still unknown. Here we describe a gene (Mpl1) in the economically important insect ...

BACKGROUND This study was initiated to search for fungal candidates for microbial control of brown planthopper (BPH) Nilaparvata lugens Stål, to which little attention has been paid in the past two decades. RESULTS Thirty-five isolates of Metarhizium anisopliae (Metschnikoff) Sorokin and M. flavoviride Gams & Rozsypal from different host insects worldwide were bioassayed for their lethal effe...

background: metarhizium anisopliae strain iran 437c is one of the most virulent fungal isolates against house fly, musca domestica . the objective of this study was to determine the interaction of this isolate with sublethal doses of spino­sad against housefly. methods: in adult bioassay, conidia of entomopathogenic fungus were applied as inoculated bait at 10 5 and 10 7 spore per gram and spin...

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 sus...
