Appetite suppressant: In 2008, insect-resistant transgenic crops expressing genes from the bacterium Bacillus thuringiensis (Bt) that control specifi c insect pests are being grown on some 40 million hectares in 25 countries. These insectresistant crops have been deployed successfully for the management of bollworms in cotton, and corn earworm and stem borers in maize – insect species that feed on many crops, including the ICRISAT mandate crops like chickpea, pigeonpea and sorghum, and cause considerable damage in farmers’ fields.
