When well-conditioned maize is stored in the tropics and in particular in the wetter areas, it eventually becomes infested with insects, The rate of infestation will depend on the conditions of storage but even efficient storage methods can fail and serious insect pest outbreaks occur. Certain methods of insect control, the most important of which is that obtained by the addition of insecticides to the grain, can delay an infestation for a considerable period permitting long storage under relatively insect-free conditions [1]. However, less efficient treatment may only retard the rate of infestation, resulting, during the storage period, in a reduction of weight and quality of the grain. In previous work on stored products little attention has been given to the effect of an insect infestation on the palatability of the grain, especially when the presence of insects has not caused severe heating to the grain. The efficiency of storage treatments has invariably been judged by the final loss in weight or number of grains damaged. If, however, a maize producer is concerned with quality, particularly if he is to sell his product for human consumption, then the effect of storage, with or without an insect infestation, on the palatability of the maize is important and should not be overlooked.
