Abstract
This chapter discusses the origin of stored-grain insect pests, the assessment of storage losses, the detection of insect infestation in stored commodities using physical, chemical and staining, the identification of insects in stored grain, and the sources of infestation. The storage structures and the traditional methods of storage are briefly described. The components of integrated pest management of stored grains, which include pest monitoring/sampling, physical, biological and chemical insecticides (including botanicals, insect growth regulators and fumigants) are described. The non-insect pests of stored grain and their management using various chemicals are also described. The existing postharvest system has to be improved to cut postharvest losses at the farm level where ∼70% of grains are stored and consumed as food and feed and for seed purposes.
