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 H. armigera revealed that H. indica caused cent per cent larval mortality of 3rd, 4th and 5th instar larvae of H. armigera at inoculum levels of 20, 40, 60, 80 and 100 IJs/larva after exposure time of 120 hrs. Third instar larvae were most susceptible to H. indica than fourth and fifth instar larva.
