Phenological studies on the white muscardine fungus Beauveria bassiana (8als.) Vuill, and Dicladispa armigera (Olivier), a serious insect pest of rice in Assam, India (Hazarika and Dutta, 1991), revealed that the fungus was adapted to the rainfed rice ecosystem. The fungus occurred naturally as an effective biocontrol agent suppressing D.armigera populations (Hazarika and Puzari, 1990; Puzari and Hazarika 1991, 1992). Agarwal (1990) showed the association of B.bassiana with egg, larva, pupa and adults of different insects with variable susceptibility to different stages. This investigation depicts such effects on the embryonic and post embryonic stages of D. armigera.
