Evaluation of four fungal pathogens against Dinoderus minutus Fab. (Coleoptera: Bostrychidae), a post harvest pest of bamboo

摘要

Efficacy of our entomopathogenic fungi, Beauveria bassiana. B. brongniartii, Paccilomyces fumoso-roseus and Aimarhizium anisopliae isolated from different host insects were evaluated in the laboratory against adult Dinoderus minutus Fab. (Coleoptera: Bostrychidae). All the four fungi were pathogenic to D. mama's. The LC50 (8.7 x 10(5) coniclia/ml) and LT50 (58.74 11) values showed that B. brongniartii was inure virulent against D. minutus under laboratory conditions, followed by B. bassiana, M. anisopliae and P. fumoso-roseus.
