摘要：
Fourteen geographical isolates of entomopathogenic fungus, Nomuraea rileyi (Farlow) Samson were tested for their germination potential. They were also screened for concentration and time mortality response against tobacco caterpillar, Spodoptera litura. Four samples were found superior in germination. The maximum spore germination was observed in isolate Nr-Kc collected from cadaver of S. litura (84.16 %) followed by isolate Nr-Mc (82.60 %), Nr-Rc (82.48 %) and Nr-Hc (82.06 %). Lowest LC50value was recorded by the isolate Nr-Kc against second and third instar larvae of S. litura (1.26 × 105and 1.60 × 106, respectively). Similarly, the isolate Nr-Kc also recorded lowest LT50value in respect of second instar (143.89 h) and third instar (178.43 h) larvae of S. litura. © 2015, The National Academy of Sciences, India.
