Abstract
Bt cotton provides in built protection to cotton against lepidopteron pests (Helicoverpa), therefore production of cotton has been increased. Due to introduction of Bt cotton socio-economic status of farmers has improved. The control provided by Bt cottons approaches immunity. No survivors have been found in field studies. Bt cotton has revolutionized our ability to implement IPM in cotton and reduced our insecticide inputs by over 60%. Each year billions of dollars are spent worldwide on insect control in agriculture. Despite this expenditure, up to 40% of a crop can be lost to insect damage, particularly in developing countries. Helicoverpa armigera is a common major pest, causing epidemics resulting into calamity. H. armigera comes in more than one peak along with pink boll worm in all cotton growing zones. A number of insecticides effectively control these insects' pests but they have been proven to be hazardous to human health and environment.
