Abstract	The insecticidal virulence of various entomopathogenic fungal isolates retrieved from soil samples was tested on adults of the granary weevil Sitophilus granarius (L.) (Coleoptera: Curculionidae). Bioassays were carried out in the laboratory where experimental adults were sprayed with 1 mL of conidial suspension (108 conidia/mL) from each isolate. Mortality was recorded at 7, 14, and 21 days after exposure. Mean mortality, mean lethal time, survival, and hazard effect were estimated for each isolate. Two isolates of Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae), one isolate of Aspergillus insuetus (Bainier) Thom & Church (Eurotiales: Trichocomaceae) and Metarhizium anisopliae (Metschinkoff) Sorokin (Hypocreales: Clavicipitaceae) resulted in the highest mortality (97–100%). The isolates with both the highest hazard effect and the lowest survival rate were Aspergillus sp. and M. anisopliae. Our results indicate that entomopathogenic fungi have the potential to become a very useful tool in reducing chemical applications in storage facilities.
