Regarding the importance of the use of biopesticides especially microorganisms such as fungi in biological control the contribution is made by studying the effect of an entomopathogenic fungus Beauveria bassiana (Bals 1853) and specifically acridopathogene on individuals desert locust Schistocerca gregaria (Forskal 1775). Preliminary tests on the study of the pathogenicity of B bassiana biocontrol agent, were made in the laboratory of fifth instar larvae (L-5) of S gregaria. Using LD 50 on the treated individuals, a study was conducted on the effect of the entomopathogenic fungus B bassiana on their cuticle. Indeed, the fungus induces disorganization of the architecture of the cuticle.
