The present study was undertaken to analyse the bio-insecticidal activity of various extracts of fungal isolates from the composite soil samples against grasshopper as test species. The fungal compound from the isolates was prepared using various extracts and the efficacy of insecticidal activity was assessed at different concentrations and at different intervals. It was found that the grasshoppers were effectively killed. Among the extracts, methanol extract of the fungal isolates was very active at 72 hours of exposure and the dosage of 50μl concentration was found to be effective with high insecticidal activity.
