Insecticides are stomach/alimentary canal poisons or fumigants to the insects. Control of insects by the use of bioinsecticides is common application in agricultural practice. Natural insecticides includeAzadirachta indica (azadirachtin), Derris (rotenone) andChrysanthemum(pyrethrum). The first commercial bioinsecticide is known as sporeine and is developed in Germany. Sporeine kills insects by inhibiting ion transport in the midgut. Genes for some of these toxins have been isolated and transferred to host through recombinant DNA technology (transgenic plants).
