Effect of Beauveria bassiana on Rhyzoperlha dominica parental adult mortality, F1 emerged adults; wheat kernels weight loss and damage were evaluated. Lesser grain borer. R. dominica adults were exposed to B. bassiana (BIOVER~ conidia powder admixed with wheat kernels in different six rates wlw (weight of B. bassiana conidial powder to weight of wheat kernels) and compared to untreated (check). Mortality percentage of R. dominicaadults increased with increasing rates of B. bassiana after seven days. Significant differences were observed between all tested B. bassiana rates (P=0.0001). The maximum percentage of adult mortality after seven days of exposure was achieved at the highest rate compared to the untreated. Same trend was recorded after 14 days of exposure (P= 0.0001) at the previously mentioned rates compared to the untreated check. Negative relationship between B.
