Characterization of a new strain of Metarhizium novozealandicum with potential to be developed as a biopesticide.

ABSTRACT: The fungal species Metarhizium novozealandicum, that occurs only in New Zealand and Australia has been poorly studied.  In this work, a new strain of M. novozealandicum isolated from a larva of Wiseana sp. is described based on morphology, genomic multilocus (ITS, EF-1α and β-tubulin) phylogeny, growth in different culture media and insecticidal activity. The isolate AgR-F177 was clustered in the same clade with M. novozealandicum. AgR-F177 colonies developed faster on Sabouraud Dextrose Agar (SDA) than on Potato Dextrose Agar (PDA) when incubated at 25°C, with no growth observed at 30°C on either media. Conidia yield on an oat-based medium in semisolid fermentation was 7.41 x 108conidia/g of substrate and a higher yield of 1.68 x 109conidia/g of substrate was obtained using solid fermenta
