Abstract

Pathogenicity, entomopathogenic fungus Metarhizium anisopliae (Metsch.) Sorokin has been recorded for the first time on rice leaf folder, Cnaphalocrocis medinalis (Guenee) (Lepidoptera: Pyralidae). Effective control of the pest was recorded under field conditions after application of spore suspension of Metarhizium anisopliae in gelatin (1 %) at 1 × 108 spores/ml on the infested rice crop. Between 5 to 7 days after treatment, 60-70 per cent mortality was recorded.
