Abstract

In this report, the insecticidal activity of Metarhizium anisopliae isolated from different geographical regions of Tamil Nadu was evaluated against Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) and Euproctis fraterna (Moore) (Lepidoptera: Lymantridae) under laboratory conditions. Among the tested isolates, Ma2 isolate at 10⁸ spore/mL was found more effective against S. litura and E. fraterna than Ma1 than and Ma3 isolates.
