A significant portion of grains are lost to biotic and abiotic factors, out of which insect pests impact food security and economic stability. The preliminary step in mitigating these post-harvest losses is to identify the pest that has infested the grains. Hence, it is essential to find a solution in managing these pests to meet the nutritional demands of the burgeoning human population. In the era of digital advancement, artificial intelligence (AI) has made significant strides across various fields. This study delves into the potential of transfer learning (TL) as a tool for reducing grain losses by identifying pests infesting stored grains. Pre-trained models like VGG16, VGG19, InceptionV3, and Xception were employed and fine-tuned for pest recognition. The performance of these models was evaluated using metrics and a confusion matrix. The accuracy of the models VGG16, VGG19, InceptionV3, and Xception were 99.8%, 99.2%, 93%, and 95.8%, respectively, whereas VGG16 achieved superior performance in accuracy, precision, recall, and F1-score metrics. Confusion matrices provided insights into model strengths and weaknesses, emphasizing the importance of architecture and training data quality. Leveraging these findings, a web tool using Flask (Python) powered by VGG16 was developed to assist farmers in pest identification. This research demonstrates the potential of Transfer learning for combating post-harvest losses and promoting food security.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102515"},"PeriodicalIF":2.7,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143104464","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}

Poorly designed ducts can result in uneven temperature distribution throughout the grain bulk, leading to localized conditions that promote fungal and insect growth, while also increasing the power consumption of the fan needed for aeration. This study aimed to evaluate the temperature distribution within bulk rough rice during aeration, using both numerical simulations and experimental methods, for three innovative inlet air duct arrangements -E, F, and H-each resembling the respective letter's shape. The study was conducted on a scaled-down model of a one-fourteenth real-size on-farm silo. Temperature data were collected at various locations within the grain bed, and the simulation outcomes were validated by comparing them to the experimental data. The results indicate that, for all three air inlet arrangements, the temperature distribution in both cross-sectional planes (parallel and perpendicular to the airflow direction) was uniform by the end of the aeration process. The time required to reach a temperature of 15.5 °C in both planes was approximately the same, highlighting the effective performance of these arrangements in different orientations. Among the duct arrangements in the experimental silo, the F-duct arrangement demonstrated superior ventilation performance, achieving the target temperature at least %25 faster than the E and H arrangements. The higher efficiency is attributed to its larger volumetric heat transfer coefficient. The H duct arrangement, however, offers other advantages, including a pressure drop that is at least 30% lower and a minimum 17% reduction in power consumption within the storage bed compared to the F and E duct configurations.</div><div>The numerical simulations closely aligned with the experimental data.

The results showed that the full mortality time of stages in highly resistant strain are obviously delayed, as well as at lower temperatures. The regression equations of adult immobilization ratio (x) and predicted time (y) of population extinction were established for the two strains, Based on this, we can calculate the completely death time of eggs and predict population extinction.

Changes in postharvest quality were monitored in irradiated (0.5, 1.0, and 1.5 kGy) mushrooms stored for 35 days. Results indicated that X-rays irradiation effectively mitigated the deterioration in appearance, color and texture of shiitake mushrooms during storage. Electronic nose (E-nose) assay revealed that 0.5 kGy X-rays delayed the aroma fading of shiitake mushrooms while higher doses of X-rays treatment changed the odor profile. After X-rays treatment, the microorganism growth was inhibited, the electrolyte leakage and malondialdehyde (MDA) accumulation were alleviated, and the contents of soluble proteins, reducing sugars, ascorbic acid (AA), and total phenols (TP) were maintained. Notably, 0.5 kGy X-rays irradiation performed superior efficacy in maintaining sensory scores and tissue structure. The study suggests that 0.5 kGy X-rays irradiation can be used as shiitake mushrooms preservation method to retain the perceptual attributes and protect against spoilage.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102500"},"PeriodicalIF":2.7,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180504","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}
