| Abstract | ||
| This study was conducted in Biology Dept., College of Science for women , Baghdad University in year 2010 to identify the effect of Biofungus Metarihizum anisopliae in some different stages of saw toothed grain beetle Oryzaephilitis suriuamensis . The eggs in age of 24 and 72 hours, Larvae in second fourth instar and pupae in age 24 and 72 were treated with fungal dilution 4.8×10 -6 , 4.8×10 -4 and 4.8×10 -2 . Results of the study showed the following : Non – hatching eggs at the age at 24 hours with fungal suspension 4.8 x 10-2, while 100% the highest mortality rate for egg , but lowest rate mortality was 23.3% of dilution 4.8 x 10-4. The highest mortality of four larvae stage 66.6% indilution 4.8 x 10-4. The highest mortality of pupa 73.3% in 72 hours. | ||
