In the present study, we evaluated the effects of S-methoprene alone and in combination with the synergist piperonyl butoxide (PBO) against susceptible (QRD14) and resistant (QRD551) strains of <em>R. dominica</em>. Bioassays were conducted on wheat treated with two concentrations of S-methoprene (0.1 and 0.3 mg/kg for QRD14; 10 and 30 mg/kg for QRD551 and two concentrations of PBO (0.27 and 1.35 g/kg). Treatments were applied under three exposure scenarios: (i) sequential application of S-methoprene followed by PBO with a 5-h interval, (ii) sequential application of PBO followed by S-methoprene with a 5-h interval, and (iii) simultaneous application of both compounds. Adult mortality was generally low in both strains, not exceeding 30 % even after 21 d, although the combination. In contrast, progeny production was almost completely suppressed in QRD14 across all treatments, while in the QRD551 strain, progeny suppression was dose-dependent and strongest when S-methoprene at 30 mg/kg was combined with PBO at 1.35 g/kg. These results demonstrate that progeny suppression, rather than adult mortality, is the key effect of S-methoprene against <em>R. dominica</em>, and that PBO can enhance its efficacy, particularly in resistant populations.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"116 ","pages":"Article 102949"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145925146","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}

This study evaluated ozone fumigation as a dual-function postharvest strategy for suppressing <em>Tribolium castaneum</em> and <em>Oryzaephilus surinamensis</em> while preserving the physicochemical and sensory quality of date fruits under semi-commercial storage conditions. Date fruit piles were exposed to ozone at 500, 700, and 1000 ppm for 5, 7, and 9 h, and insect mortality, feeding performance, growth, metabolic efficiency, progeny production, and commodity weight loss were assessed alongside detailed quality analyses. Ozone fumigation induced concentration- and time-dependent increases in insect mortality, reaching near-complete lethality after prolonged exposure. Beyond acute toxicity, ozone significantly reduced relative growth rate, relative consumption rate, and efficiency of conversion of ingested food, while markedly increasing feeding deterrence and suppressing F₁ progeny production. These biological effects translated into a substantial reduction in insect-mediated weight loss of date fruits. Importantly, ozone treatment did not adversely affect the chemical composition of dates, and only minor changes were observed in selected physicochemical attributes, including pH and water activity, without compromising firmness, color, or overall sensory quality. Correlation and principal component analyses indicated that most physicochemical quality variables clustered separately from bioefficacy metrics, while odor aligned more closely with higher CT intensity, highlighting odor as the main quality constraint during optimization. Overall, the findings demonstrate that ozone fumigation offers an effective, residue-free postharvest disinfestation strategy capable of suppressing stored-product insect populations while maintaining the quality integrity of date fruits.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"116 ","pages":"Article 102993"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147395374","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}

Results demonstrated that HAD outperformed VD, exhibiting higher drying rates, less color degradation (smaller ΔE values), and better preservation of microstructure and structural integrity.

This study investigated the efficacy of electron beam irradiation (EBI) at 2.0 kGy in delaying the softening of fava beans and elucidated the underlying physiological and molecular mechanisms. During the 20-day storage period at 4 °C, EBI-treated beans exhibited a 51 % higher hardness index than the control on day 20. This improvement was attributed to the suppression of key cell wall–degrading enzymes, including cellulase (C_x) and pectin methylesterase (PME). Correspondingly, the expression levels of their respective genes, <em>Vicia faba</em> C_x gene (<em>Vf C</em>_<em>x</em>) and <em>Vf PME</em>, were downregulated by 24 % and 18 % on the 20th day, thereby helping to maintain the structural integrity of the cell wall. EBI treatment also helped maintain higher contents of cell wall polysaccharides, including cellulose, pectin, and lignin. Transmission electron microscopy (TEM) revealed that EBI aided maintain plasma membrane–cell wall adhesion and mitochondrial integrity, supporting normal cellular function. Furthermore, EBI optimized the membrane lipid composition: on day 20, the ratio of unsaturated to saturated fatty acids (U/S) in the EBI-treated group increased by 112 %, indicating enhanced membrane stability. In summary, 2.0 kGy EBI delayed softening in fava beans by modulating cell wall integrity and membrane lipid homeostasis.

The long-term mixing of healthy and defective sweet potatoes during storage accelerates the physiological deterioration. This significantly reduces their edible quality and market value. To address this issue, this research presents SP-YOLOv11, a high-performance defect detection method designed to identify and grade four surface conditions of sweet potatoes in complex harvesting environments, including intact skin, minor defects, moderate defects, and severe defects. Specifically, first, a CPPA module is introduced, which employs a multi-branch feature extraction strategy to enhance the model's feature representation and detail-capturing ability. Next, an FDPN module is constructed, which, through multi-scale fusion and feature diffusion mechanisms, improves the adaptability to defects of different scales. Finally, an MSE-Detect module is introduced to focus on the key defect areas of sweet potatoes, further enhancing robustness in agricultural scenarios. To validate the effectiveness, eight ablation experiments are conducted. The results show that SP-YOLOv11 achieves the highest detection accuracy for sweet potato defects, with <em>mAP@</em>0.5 and <em>mAP@</em>0.5:0.95 reaching 98.50 % and 85.60 %, respectively. This research effectively overcomes the challenges of low efficiency, poor accuracy, and high damage rates in traditional defect detection methods. It significantly reduces the spread of diseases and physiological deterioration, while enhancing the post-harvest freshness retention and storage quality of sweet potatoes.
