The red flour beetle (Tribolium castaneum) is a common pest insect known for attacking and infesting stored flour and grain. They are one of the most common and most destructive insect pests for grain and other food products stored in silos, warehouses, grocery stores, and the home. Bacillus thuringiensis (B.t) is a Gram positive, soil dwelling bacteria commonly used as a biological alternative to a pesticide. The present project was designed for the study of combined insecticidal effect of Bacillus thuringiensis along with boric acid, insecticide cypermethrin and the plant leaves powder i.e...

Bacillus thuringiensis spore forming, Gram positive aerobic bacteria whose spores consist of the crystal protein which are found to have the insecticidal activity to the specific insect orders. Bacillus thuringiensis are considered to be cosmopolitan in nature and a great difference occurs between the two strains from different habitat. The present study was conducted on the collection of samples and solation of the B.t. from these samples. These isolates were identified on the basis of microscopic techniques and staining techniques. Culturing of these isolates was made on the specific media...
