Entomopathogenic fungi produce secondary metabolites which may bio actively help fungus in its virulence toward insect hosts. Beauveria bassiana  produces several toxic low molecular compounds in vitro as well as in vivo, the most important of them is Beauvericin. The Beauveria bassiana  fungus isolated was selected for Toxin assay. Various Toxins  was obtained from surface and submerged cultures of the fungus in PDYB and PDA, culture filtrates, and in vivo conidia harvested from insect cadavers. Results indicated that in vivo fungal conidia contained the most Beauvericin, causing a higher mortality compared with in vitro fungal products in their different concentrations. Beauvericin chromatogram revealed that Beauvericin was in its greatest quantity in comparison with the other secondary metabolites of Beauveria bassiana  isolate. The impact of Beauvericin on mean and on paralysis time was in agreement with bioassay data in treated with metabolites of the insect-derived conidia.
