Abstract

The pathogenicity test of different isolates of Beauveria bassiana and Metarhizium anisopliae at 1 x 10conidial mL-1 suspension was evaluated against rice grain bug adults in the laboratory. Mortalities of the rice grain bugs treated with the different isolates of M. Anisopliae did not differ significantly in 50-70% and 56.67-73.33% mortality after 12 days post treatment regardless of the treatments applied in trials 1 and 2, respectively. The insects treated with B. Bassiana isolates had lower mortality ranging from 3.33 to 26.67% in both trials. Thus, M. anisopliae was more pathogenic to rice grain bug than B. bassiana in the laboratory. In both trials, the insects started to succumb due to fungal infection in 3-5 days post treatment.
