Biocontrol Potential of Entomopathogenic Nematodes Heterorhabditis and Steinernema Against Second Instar Grub of White grub, Leucopholis lepidophora (Blanchard)

The effectiveness of two entomopathogenic nematodes (EPN) viz. , Heterorhabditis indica strain NBAII-104 and Steinernema carpocapsae strain NBAII-04 against second instar grubs of L. lepidophora (Blanchard) under pot culture experiment. At aconcentration of 450 IJs ml-1, H. indica recorded highest mortality (87.60 %) at 15 DAT. While, S. carpocapsae recorded 54.05 per cent grub mortality at 450 IJs ml-1 at 15 DAT. We concluded that the NBAII-104 strain of H. indica was most virulent against second instar grubs of L. lepidophora.
