abstract
The present study is related to the Spodoptera litura (Fabricius), which is one the most important insect pest of the crops, vegetables, pulses, groundnut. An Entomopathogenic Fungi, Paecilomyces lilacinus was isolated from the soil. The media used for the isolation is PDA (Potato Dextrose Agar) in addition with Yeast extract and Chloramphenicol was used as antibiotic. The artificial rearing of S. litura was done in laboratory by providing artificial diet and natural diet. Adult stage was used for test experiment. Five different concentration (1x10⁴, 1x10⁵, 1x10⁶, 1x10⁷, 1x 10⁸) were used for the test experiment. Isolated Fungus show the maximum pathogenicity/ mortality at the spore concentration of 1x 10⁶ spore ml^-1.
