Abstract: The rice weevil, Sitophilus oryzae is among the most damaging stored cereal pests globally, causing severe post-harvest losses and significantly impacting grain quality. A member of the superfamily Curculionoidea, it has a sophisticated life cycle and exceptional adaptability to varied environmental conditions, enabling infestations to develop well in stores. Its feeding damages grain weight, drains nutrients, decreases germination, and reduces market value. Although chemical pesticides will control the pest efficiently, excessive use has raised issues of pesticide resistance, toxicity, and environmental contamination. These issues have prompted research into safer, environmentally friendly alternatives. Integrated pest management (IPM) strategies integrating botanical pesticides, biological control, physical treatments, and advanced molecular tools are yielding encouraging results in sustainable control. Recent studies further highlight the importance of genetic research, novel biocontrol products, and precision agriculture in optimizing the efficiency of pest management. This review synthesizes existing information on the rice weevil's taxonomy, life history, feeding habits, and management, with the ultimate goal of enabling more effective and environmentally sustainable management.
