Bacillus thuringiensis, commonly referred to as B.t. is a gram positive bacterium that produces insecticidal crystal proteins. This bacterium occurs naturally in the environment and has been used as a biological pesticide for more than 50 years. In order to manage the loss of stored grains and other agricultural products from insect infestation, many plant products have been evaluated for their toxic properties against different stored grain pests. In the present study, B.t. isolates from collected samples were grown on T3 (Tryptone, Tryptose, Yeast extract) media.
