This study explores farmers' perceptions of maize grain quality standards, the challenges they encounter in maintaining quality for industrial use, the strategies they adopt to manage quality, and the factors that influence maize quality. The findings indicate that farmers recognize the importance of maize quality but face misconceptions about certain quality aspects, particularly regarding broken or moldy grains. In terms of quality control measures, farmers perceive them as both difficult and costly to implement, citing high costs for certified seeds, labor, and storage facilities as major barriers. Farmers rely on a range of strategies to manage maize quality, focusing on pre-harvest and post-harvest activities such as drying, timely harvesting, sorting, and storing in well-ventilated spaces. Female farmers and those with higher education levels are more likely to meet quality standards, while older farmers face higher rejection rates due to reliance on traditional practices. Key factors influencing maize quality include access to modern storage facilities, knowledge and training in quality standards, and the influence of age, gender, and education. The study also highlights significant logistical challenges, such as inadequate transportation infrastructure and long distances to warehouses, which hinder farmers' ability to maintain maize quality. Despite these constraints, farmers employ a combination of preventive and corrective measures to enhance quality. The study emphasizes the need for targeted interventions, including cost-effective quality control solutions, improved training on modern practices, and better storage and transportation infrastructure to help farmers meet industrial maize standards, improve their productivity, and enhance their livelihoods.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"112 ","pages":"Article 102630"},"PeriodicalIF":2.7,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenging problem and shift away from dependence on chemical pesticides to more sustainable nanotechnology-based approaches, this paper presents a study exploring the combined use of graphene and biopesticide for advanced pest control. Naturally derived spinosad as a natural neurotoxin with lower resistance risks was combined with graphene-based nanopesticides offering efficient, and environmentally friendly pest control are explored to manage three key pests of stored products: <em>Tribolium castaneum</em> (Herbst), <em>Oryzaephilus surinamensis</em> (L.) and <em>Rhyzopertha dominica</em> (F.).

Mortality rates were measured at 7-, 14-, and 21-days post-exposure, while progeny production was evaluated 65 days after treatment. Results indicated that the combination of graphene and spinosad significantly increased insect mortality across all three species when compared to either substance alone. <em>Rhyzopertha dominica</em> was the most susceptible in all spinosad treatments, both alone and in combination with graphene. <em>Oryzaephilus surinamensis</em> showed 97% mortality in graphene/200 spinosad, while <em>T. castaneum,</em> known for its tolerance to spinosad, showed lower mortality rates. Regarding progeny production, <em>O. surinamensis</em> exhibited zero progeny in all graphene-spinosad treatments, while <em>R. dominica</em> recorded complete inhibition of progeny in all treated groups. In contrast, <em>T. castaneum</em> showed fewer offspring compared to untreated controls.

All formulations demonstrated higher toxicity after 14 days of exposure than DE alone. Notably, 30% ZnO showed a substantial increase in toxicity, with relative potencies of 6.82, 6.05, and 7.08-fold compared with DE alone against <em>T. castaneum, R. dominica,</em> and <em>O. surinamensis</em> respectively.

Reducing grain losses and ensuring grain quality have extremely important practical implications. Enhancing the granary's intelligence is particularly important due to several issues affecting residue grain sweeping, including manual inefficiency, incomplete coverage, and expensive equipment. This work proposes a new method called the Residual Grain Sweeping Visual Large Mode (RGSVLM)¹ based on the Visual Large Language Model (VLLM). First, we constructed a semantic dataset containing images of various residual grain dispersal patterns captured in real granary environments. We also introduced an improved version of the Fast Segment Anything Model (FastSAM) algorithm to detect residual grains in the field images, extract visual features, and achieve accurate segmentation. In addition, we crafted prompt engineering that combines image data to produce corresponding textual datasets that effectively reflect the real-world situation. Next, we integrated this dataset with a chain of reasoning framework to fine-tune the visual large language model for specific tasks. This approach compensates for the original model's limitations in logical reasoning, enabling it to simulate human thought processes and generate clear and reasonable answers. In a granary environment, RGSVLM performs better than other models.

The aims of this study were to evaluate 1) direct lethality, and 2) sublethal effects of exposure to two LLINs on semiochemical-mediated foraging and movement by <em>T. granarium</em>. Direct lethality was examined on larvae after a 5- or 60-min exposure to control netting (without insecticide), a 0.34% alpha-cypermethrin (Carifend, BASF), or 0.4% deltamethrin LLIN (D-Terrence, Vestergaard, Inc.) over 168 h. Sublethal changes in movement were evaluated immediately after a 5-min exposure. Finally, semiochemical-mediated foraging was evaluated 24-h after LLIN exposure by larvae in a release-recapture assay using pitfall traps baited with either no stimulus, food cues, or the sex pheromone for <em>T. granarium</em>. The recovery of larval <em>T. granarium</em> dramatically rose and peaked 72–168 h after exposure to LLINs, while the percentage of alive individuals in the control remained consistently high.

There was a 6.6-fold higher capture of larvae in traps after exposure to control compared to deltamethrin netting. Elevated response to food cues was suppressed after exposure to LLIN. Overall, there is evidence of significant impacts of LLIN on <em>T. granarium</em>, but high recovery after short exposures and subsequent unresponsiveness to pheromone-baited traps, which are critical for species detection, suggest limitations for using LLIN in management for <em>T. granarium</em>.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"112 ","pages":"Article 102615"},"PeriodicalIF":2.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular diagnostics, particularly DNA-based techniques, offer a promising alternative for improving pest detection accuracy in a grain sample. This study, conducted as part of the INSECT-FREE project, aimed to assess the perspectives of the European agrifood sector on the adoption of molecular diagnostic tools for insect detection. A structured survey was distributed to over 50 companies, including flour mills, grain storage facilities, and food processors, to evaluate current pest management practices, challenges, and the willingness to adopt DNA-based detection methods for insects detection. Results showed that over 90% of respondents considered the presence of insects to be a major concern, with traditional detection methods still dominant. However, 70% of companies using molecular techniques for other quality control applications, such as GMO and mycotoxin detection, expressed interest in incorporating DNA-based pest detection. This indicates a significant demand for reliable, rapid, and sensitive detection methods, emphasizing the potential for integrating molecular diagnostics into pest management strategies. The implementation of these molecular techniques could improve food safety, reduce economic losses, and support regulatory compliance.
