Innovative Approaches for Weevil Infestation Prevention in Rice
Weevil infestations pose a significant threat to rice grain quality, making it a critical concern for one of the most widely consumed cereals globally1. Indeed, Sitophilus species contribute to commercial losses and quality degradation2,3. Consequently, it becomes imperative to devise effective solutions that guarantee quality and safety for consumers.
The prevailing method for preventing insect presence involves the application of chemical substances. However, the increasing scrutiny from consumers and regulators arises due to concerns about the development of insect species resistance to these chemicals4. The implementation of non-chemical, effective methods to prevent weevil infestations is poised to enhance the productivity and income of rice producers and traders. Moreover, it brings about environmental benefits while ensuring consumer well-being.
This research will systematically pursue various objectives, including mapping out the physical and biological treatments proposed and currently utilized to prevent insect growth during rice storage. Additionally, it will focus on developing swift and precise methods for detecting hidden infestations, conducting tests on the application of selected treatments to prevent insect infestations, quantifying the cost-benefit ratios of each approach on an industrial scale, and evaluating the impact of each treatment on the chemical and organoleptic quality of rice.
The findings derived from this study will hold substantial value not only for other stored cereals but also for various insect species impacting these products. This is particularly pertinent given the substantial bio-ecological and taxonomic affinities among the primary pests affecting these commodities.
