Ecological Management of Stored Grain Pests: Global Insights and Future Directions

Abstract Post-harvest losses due to pests in cereals and pulse warehouses represent a major challenge to global food security. These losses have widespread negative impacts on the food supply chain, leading to the widespread use of synthetic insecticides to control the spread of pests in stored commodities. Although these chemicals are initially effective against warehouse pests, their prolonged use leads to increased resistance, resulting in increased health and environmental risks. In addition, the residues left by these synthetic insecticides can alter the quality of stored food, thereby posing a threat to human and animal health. In response to this problem, several studies have focused on ecological management aimed at combating warehouse pests without compromising the quality of stored grain. These studies include an assessment of traditional, ecological, and modern approaches as well as a summary of technological advances in cereal storage. This analysis describes new emerging ecological methods such as varietal resistance, use of semiochemicals, and physical and biological control methods. The challenges and research prospects associated with ecological practices were also discussed. It is emphasized that ecological control is not only safer and more sustainable in the long term but also contributes to the preservation of the environment and human health by reducing exposure to harmful substances.
