Electrophoretic karyotypes of eight wild-type strains of Metarhizium anisopliae var. anisopliae were obtained by pulsed-field gel electrophoresis. These strains were isolated from insects of six different Brazilian states. The chromosomal DNA molecules of three strains were separated into seven bands and of five strains into eight bands. Chromosome length polymorphisms were also observed. The s...

Reniform nematode, Rotylenchulus reniformis received greater attention due to its polyphagous nature, cosmopolitan distribution and adaptability different agro-ecological condition. It causes great losses pulses including Mungbean (Singh, 2015). Therefore, an experiment was carried out test the efficacy of botanicals manage reniform nematode infecting summer mungbean. Bioagents i.e. Metarhizium...

In the present study, four fungal isolates (Metarhizium anisopliae) were isolated and examined for their sporulation characteristics and virulence against Coptotermes formosanus. Initially fungal strains were isolated through insect bait (Galleria) method. The mortality was significantly varied between 2 to 4 days. nd th In in this study inspection, the mortality of termites was observed after ...

Mortality of German cockroaches, Blattella germanica (L.), caused by Metarhizium anisopliae (Metschnikoff) Sorokin strain AC-1 alone and in combination with different formulations of boric acid, was evaluated in laboratory bioassays. Topical application of M. anisopliae alone (8.96 10 conidia/m) required 28 days to cause >92% cockroach mortality (LT50 10 days). In contrast, in combination with ...

Genetically engineered maize producing the insecticidal protein Cry3Bb1 from Bacillus thuringiensis (Bt maize) is protected against corn rootworms (Diabrotica spp.), which are serious maize pests in North America and Europe. The aim of the present study was to investigate the interaction of Bt maize (event MON88017) and the entomopathogenic fungus Metarhizium anisopliae for controlling the west...

Entomopathogenic fungi are potential tools to biocontrol cicadellids and delphacids, two groups of insects that cause extensive damage to agricultural crops. However, bacteria living on the host cuticle may inhibit fungal growth. In the present work, following the molecular characterization of 10 strains of Bacillus isolated from the integument of cicadellids and delphacids, we selected isolate...

The three fungal pathogens Metarhizium anisopliae (Metchnikoff) Sorokin (Hypocreales: Clavicipitaceae), Paecilomyces fumosoroseus (Wize) Brown & Smith (Deuteromycotina: Hyphomycetes), and Beauveria bassiana (Bals.-Criv.) Vuill. (Hypocreales: Clavicipitaceae) were evaluated as potential biological control agents against the cactus moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae). The ...

We investigated the fungal entomopathogens Beauveria bassiana and Metarhizium anisopliae to determine if endophytic colonization could be achieved in cassava. An inoculation method based on drenching the soil around cassava stem cuttings using conidial suspensions resulted in endophytic colonization of cassava roots by both entomopathogens, though neither was found in the leaves or stems of the...
