Abstract

Fifteen isolates of Metarhizium (Nomuraea) rileyi collected from field populations of Spodoptera litura (F.) and Spodoptera frugiperda J. E. Smith in different crops across different agroclimatic zones of Andhra Pradesh were evaluated for their pathogenicity against third instar larvae of S. litura at the Biocontrol Laboratory, Regional Agricultural Research Station, Tirupati, India. Virulence was tested by applying conidial suspension @ 1x107 spores ml–1 on the groundnut leaves on which the larvae were allowed to feed. The cumulative mean larval mortality to the extent of 75.00 to 85.00% was observed with isolates viz. Nr.Yj.KZ, Nr.Dp.KZ, Nr.Rt.KZ, Nr.Rd.HATZ, Nr.Pp. HATZ and Nr.Cp.HATZ whereas the isolates Nr.Ik.SRZ, Nr.Vg.SRZ, Nr.Pl.SZ, Nr.Ag.SZ, Nr.Np.SRZ, Nr.Rp.SZ, Nr.Rg.NCZ, Nr.Hv.SRZ and Nr.Cd.SZ recorded 65.00 to 73.33% mortality.
