A laboratory strain of  Trichoderma  album Preuss was assessed against the first larval instar and adult stage of Rhzopertha  dominica  F. under laboratory conditions by dipping bioassay. Four dose rates of T. album (7 ×10⁴, 7 ×10⁵, 7 ×10⁶ and 7×10⁷ conidia /ml) were applied. The count for mortality was made after 1, 3, 5 and 7 days. The treated wheat with T. album well as untreated wheat sample were stored for 6 months after infestation with R. dominica  . and the quality of the stored wheat was determined. The results showed that the first larval instar was more highly susceptible than the adult stage. The highest mortality percentages were 94% and 74% for T. album against  R. dominica first larval instar and adult stages, respectively, after 7 days exposure at 7×10⁷ conidia /ml. the LC₅₀ value was 5.61x10⁵ and 3.32x10⁶ conidia /ml while the LT₅₀ recorded at 4.02 and 6.43 days at 7 ×10⁷ conidia /ml on R. dominica first larval instar and adult stages, respectively. Wheat properties were enhanced during storage for treated wheat comparing to untreated wheat which it reduced weight loss by 26% also gluten content and color quality of wheat were improved after treatment with . T.album. These results indicate that the entomopathogenic fungus T. album has the potential to be a biocontrol agent for controlling  R. dominica and a suitable candidate further for research and development.
