A medium was developed with rice hull, saw dust and rice bran at a ratio of 75:25:100, respectively, to mass culture Beauveria bassiana (Balsamo) Vuillemin, a potential biocoritrol agent against the rice hispa, Dicladispa armigera (Olivier) (Coleoptera:Chrysomelidae). It produced 39.33 × 107 conidia/ml of water 24 days after inoculation. The mortality of the adult could be achieved up to 78.6 per cent at spray concentration of 106 spores/ml of water.

Abstract


A medium was developed with rice hull, saw dust and rice bran at a ratio of 75:25:100, respectively, to mass culture Beauveria bassiana (Balsamo) Vuillemin, a potential biocoritrol agent against the rice hispa, Dicladispa armigera (Olivier) (Coleoptera:Chrysomelidae). It produced 39.33 × 107 conidia/ml of water 24 days after inoculation. The mortality of the adult could be achieved up to 78.6 per cent at spray concentration of 106 spores/ml of water.
