A topical bioassay was performed on southern mole crickets to determine the effects of combining Beauveria bassiana with either imidacloprid or diatomaceous earth. Field collected adult mole crickets were placed in a potting soil substrate treated with imidacloprid or D.E. for 48 hours before being topically treated with Beauveria bassiana. After the B. bassiana treatments, the crickets were returned to the pre-treated substrate. Three different Orthoptera-isolated strains of B. bassiana were evaluated in this study. All three products (B. bassiana, imidacloprid and D.E.)were applied at sub-lethal doses to check for additive, antagonistic, or synergistic effects. Crickets were checked daily for 28 days for mortality and cadavers were incubated to determine percentage fungal bloom for each treatment. Results from this study will be presented.
