Abstract

Bacillus thuringiensis (Bt) is a widely employed pest management biocontrol agent in the agriculture and forestry ecosystem. In nature, this gram-positive bacterium is found in soil that produces spore-crystal inclusion bodies. This gram-positive bacterium produces a broad spectrum of insecticidal proteins, which are found to be extremely toxic to different groups of insect pests. Bt toxin genes are very selective and specific to pests; they are not toxic to other than the target organisms such as human, animals, and birds, and they are safer for the environment. The Bt toxin is often employed in organic farming as an insecticide spray to manage insect pests. Additionally, it is one of the sources for the insecticidal genes deployed to genetically modify food crops so that they can naturally impart resistance against numerous insect pests.
