Bio-efficacy of entomopathogenic nematode Heterorhabditis indica against Spodoptera litura (Fabricius)

Abstract

The investigations on bio-efficacy of entomopathogenic nematode, Heterorhabditis indica against Spodoptera litura (Fabricius) was carried out at Biocontrol Research Laboratory, Department of Entomology, Junagadh Agricultural University, Junagadh during 2014-15. Bio-efficacy of H. indica against S. litura discovered that the larval mortality of S. litura directly proportional to dose of infective juvenile and time of exposure. At 120 hrs after application, cent per cent larval mortality was recorded at all the doses (20, 40, 60, 80 and 100 IJs/larva) of S. litura.
