ABSTRACT
Stored-product insects are serious pests of dried, stored, durable agricultural commodities and of many value-added food products and nonfood derivatives of agricultural products worldwide. There are several techniques for detection of insect infestation available for commercial or small level of storage. These techniques are manual sampling, probe and insect traps, sieving, floatation, X-ray, utilization of specific chemicals for hidden infestation, and Berlese funnels. Generally visual inspection of storage structure and stored commodities is very popular, and therefore any results can only be recorded in a descriptive way. The solid phase micro extraction technique is inexpensive, rapid, and heat sensitive for detection of insect infestation. Floatation method consists from two solutions of chemicals sodium silicate and methyl chloroform at different specific gravity. Electronic nose is the newer and excellent approach for grain odor detection. The infestation of stored grain insects can be detected with the help of molecular tools.
