ABSTRACT: Environmental concern issues controlled the chemical pesticides usage since residue might cause a health problem. An alternative safe way for pest control is the main objective of this investigation. The recent study was conducted to evaluate the effect of some Entomopathogenic Fungi (Penicillium sp) to control the rust red beetle (Tribolium castaneum). different concentrationsof fungal extract (10, 30, 50%) were appliedbeside,40 % application of the whole fungal organ against insects.Results from this investigation showed that, the treatment withEntomopathogenic fungus Penicilliumsp. affected significantly (P <0.05) the numberof living insects. Higher effect on the number of the living treated insects was observed by the third concentrations (50%)compared with other concentration (10% and 30%) in the first treatment.The treatment with the whole fungus organs showed high effect on the number of the live insects where after 7 days all the insects were dead. Generally the concentration of the extract, the days of exposture and the interaction between days and concentration had significant effect on the live number of insects.Furthermore, metabolomics study of extracts by the means of GC-MS must be studied for determination of the active compounds by means of chromatographic techniques.
