Efficacy of genetically transformed Metarhizium anisopliae against Spodoptera litura and Aphis craccivora.

ABSTRACT: To increase the insecticidal potency of the entomopathogen, Metarhizium anisopliae (Metsch.) Sorok, the fungus was genetically modified with scorpion neuro β-toxin LqqIT1a and two different insect specific heterologous toxic proteins viz., Cry1a and GNA. LqqIT1 is an anti-insect neurotoxin derived from yellow scorpion, Leiurus quinquestriatus quinquestriatus (Ehren.). The present study reports the bio-efficacy of genetically modified fungus, M. anisopliae, in which scorpion neurotoxin gene 'LqqIT1' is stacked in its genome, for improved efficacy against the tobacco caterpillar, Spodoptera litura (Fab.) and Aphis craccivora (Koch). All the transformed clones of M. anisopliae were found potent against S. litura and A. craccivora
