Today, one of the main global challenges is how to ensure food security for a growing world population. Globally, India is the second most populated country after china, in order to feed the extraneous population the concern towards food safety, security and quality, increasing day by day from producer to consumer aiming to do hunger free country. Agriculture is mainly depending on climate and the farmers are facing hectic constraints from farm to till it reached to fork. Post-harvest losses of food grains in India are 7-10 per cent of the total production and the losses in storage is mainly due to insect pests associated with grains in order solve the problem the techniques which are more prevalently in use are heat treatment and fumigation with chemicals but there are only few available fumigants. In addition, there are environmental concerns and low level of resistance to phosphine exists in stored grain insects. This leading to affect the grain quality and increases insecticide residues resulting difficulties in the long run. The permanent solution to solve the many problems by exposure of relevant development stages of major stored grain insects to high concentrations of carbon dioxide around (98%) for short intervals (5-20 minutes) produce maximum mortality. Thereafter, work is concentrating on modified atmosphere and hermetic storage.
