Highlights • The manuscript deals with the characterization of lepidopteran-specific cry1 and cry2 gene harbouring Bt isolates.• We were able to find certain Bt isolates containing both cry1 and cry2 genes.• Both cry1 and cry2 genes were found in isolates containing vip3A genes, hence can result in complementation of toxicity.• 13.63% of the Bt isolates were found to be toxic against Helicoverpa armigera.
