L'explosion démographique des pays en développement dans le monde entier crée une demande sans précédent pour une plus grande production de céréales alimentaires. Dans les pays en développement, les céréales et les légumineuses sont produites principalement dans de petites exploitations. Les agriculteurs conservent une partie de la récolte pour leur propre consommation et vendent éventuellement le reste à la population urbaine. La préservation de la qualité des céréales au niveau de l'exploitation revêt donc une grande importance. Il s'agit toutefois d'une tâche difficile, en particulier dans les régions tropicales et subtropicales où les technologies de séchage et de stockage sont déficientes, voire inexistantes. Les insectes et les champignons des grains stockés provoquent de graves pertes quantitatives et qualitatives qui ont de lourdes conséquences sur la disponibilité des denrées alimentaires, en particulier dans les régions du monde où le stockage des grains est mal géré en raison de l'absence de connaissances et de technologies appropriées. Afin de prévenir les pertes excessives de qualité et de quantité pendant le stockage des céréales, les pratiques de séchage artificiel et d'aération réfrigérante, ou l'utilisation d'insecticides, sont les techniques les plus couramment utilisées par les pays qui en ont les moyens. Les pays en voie de développement, quant à eux, ont surtout eu recours à l'utilisation d'insecticides.
