Grains are stored in large quantities all over the world and form the basis of human food supply. Huge quantities of grain must be stored and transported under conditions that ensure good preservation, preventing losses in the quantity and in the quality of the grain. Nevertheless, postharvest grain damages are still very high, from 1% to over 50% in less-developed countries, where preservation and storage are poorly managed. There is an urgent need to develop grain-storage management at farm and community level, to improve training and extension services, and to develop suitable pest-control strategies using either chemical or non-chemical methods. Storing grain while preventing quality and quantity losses is based upon recognition of the characteristics of the grain itself, and of the grain in bulk. Deterioration results from the interrelationships among physical, chemical, and biological factors, which may act differently under certain climatic conditions. Complete understanding of the princi

ples by which the environment influences the components of the bulk grain is thus the key to planning strategies which will prevent grain damage.
