Abstract:
The present investigation on “Pathogenicity of Metarhizium anisopliae against Spodoptera frugiperda larvae under laboratory conditions” was carried out at Biocontrol Laboratory, Department of Entomology, Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri during January 2021. In order to study the pathogenicity of Metarhizium anisopliae against Spodoptera frugiperda second and third instar homogenous larvae of Spodoptera frugiperda were selected. The bioassay was conducted by larval dip method (Ramanujam et al., 2020). Different doses of Metarhizium anisopliae 1.15% WP formulations viz., 0 g/litre, 2.5 g/litre, 5 g/litre, 7.5 g/litre and 10 g/litre were evaluated against second and third instar larvae of Spodoptera frugiperda in laboratory. The results revealed that highest mortality was obtained in second instar larvae with mortality ranging from 0% to 81.38% whereas, third instar larvae showed lower mortality than second instar larvae ranging from 0 to 72.77% using different doses of Metarhizium anisopliae 1.15% WP.
