| Abstract | ||
| The virulence of different fungal isolates of Beauveria bassiana and Metarhizium anisopliae to the lesser grain borer Rhyzopertha dominica (Fab.) was tested. The results showed highest mortalities for isolate of B. bassiana 3000 were 35, 50 and 50 % on periods 7, 14 and 30 days respectively, but isolate of M. anisopliae 2000 caused mortalities 35, 45 and 50 % on periods 7, 14 and 30 days respectively. When mixed isolates of fungus, appeared highest mortality for isolate B. bassiana 3000 + isolate M. anisopliae 2000 was 51.7 %, the lowest mortality was 25.8 % when mixed fungus isolates B. bassiana 3001 + M. anisopliae 2000. Highly significant differences were demonstrated for B. bassiana 3000 and 3001 and for M. anisopliae 2000. | ||
