Abstract The present study was conducted to survey and isolate entomopathogenic fungi as endophyte from wheat and tomato plants in Assiut, Upper Egypt. Two species of agricultural economic plants (wheat and tomato) were freshly collected two times / month. These plants were wheat and tomato. Plants with no visible symptoms of disease were carefully selected after physical examination. In the present study 30 samples (6 from wheat and 24 from tomato) were surveyed for entophytic fungi. Leaves, shoots, and roots of the two plants were examined. Thirty-three fungal species which belong to 17 genera were isolated as endophytes of the two plants. Beauveria bassiana was successfully isolated from the leaves of tomato (Solanum lycopersicum L.). Moreover, the pathogenicity of this isolate was assayed as endophyte on tomato and wheat plants. Also, the isolate of B. bassiana was assessed against the greater wax moth, Galleria mellonella L
