Abstract

Potato broth, rice gruel, coconut water, rice husk, sawdust and rice bran were evaluated for mass culturing of Beauveria bassiana (Bals.) Vuill (Strain AAU-09). Amongst the solid media rice husk in addition of 2% dextrose was superior to others in terms of spore production (6.25 x 10⁷ conidia/ml) and pathogenicity (86.67%) to Dicladispa armigera (Olivier) adults. Likewise, amongst the liquid media potato broth supplemented with synthetic chitin (2%), dextrose (2%) and peptone (2%) supported maximum spore production.
