Detection Techniques for Insect Infestation in Stored Grains

Food grain storage is an inevitable step in the grain ecosystem. During storage various abiotic and biotic factors interact with the food grains. Among those factors, the likelihood of pest infestation is very high. Infestation due to insects can not only cause quality and quantity loss in stored grains, it can also make the grain unfit for consumption. Storage structures are also affected due to insect infestation, thus contributing to huge loss. Hence, it is important to monitor insect infestation in stored grains. The objective of this work is to give an overview of the various detection techniques adopted to monitor pests of stored food grains. The principle of these techniques as well as their pros and cons are also explained to provide better understanding and aid in adopting the suitable technique.
