A explosão demográfica dos paÃses em desenvolvimento em todo o mundo está a criar uma procura sem precedentes de uma maior produção de cereais alimentares. Nos paÃses em desenvolvimento, os cereais e as leguminosas são produzidos principalmente em pequenas explorações agrÃcolas. Os agricultores retêm parte da colheita para consumo próprio, acabando por vender o restante à população urbana. A preservação da qualidade dos cereais a nÃvel das explorações agrÃcolas é, por conseguinte, de grande importância. No entanto, esta é uma tarefa difÃcil, particularmente nas zonas tropicais e subtropicais onde as tecnologias de secagem e armazenamento são deficientes ou completamente inexistentes. Os insectos e os fungos que atacam os grãos armazenados causam graves perdas quantitativas e qualitativas, que têm sérias implicações para a disponibilidade de alimentos, especialmente nas zonas do mundo onde o armazenamento de grãos é mal gerido devido à falta de conhecimentos e tecnologias adequados. Para evitar perdas excessivas de qualidade e quantidade durante o armazenamento de cereais, as práticas de secagem artificial e de arejamento por arrefecimento, ou a utilização de insecticidas, são as técnicas mais utilizadas pelos paÃses que as podem pagar. Os paÃses em desenvolvimento, no entanto, recorreram principalmente à utilização de insecticidas.
