A seed moisture isotherm shows the relationship between moisture content (MC) and water activity (<em>a</em>_w) at a constant temperature. Seed MC is higher when it dries from a hydrated state (desorption) than when it rehydrates from a very dry state (adsorption) to the same RH, an effect known as hysteresis. Seeds on the desorption isotherm will age faster than seeds on the adsorption isotherm at the same RH due to higher MC, resulting in a more rapid decline in seed viability and vigour. In this study, moisture isotherms of seeds from diverse species were determined and modeled using the Guggenheim-Anderson-de Boer (GAB) model; the hysteresis effect was then quantified. The maximum hysteresis magnitude varied between 0.3 and 2.7% MC (occurring between 49 and 57% RH) when seeds were dried over silica gel (below 11% RH) and rehydrated. Cycling seeds between 30 and 50%, 20 and 50%, and 15 and 50% RH, it was found that seeds of barley, lupin, buckwheat, wheat and pea switch to the adsorption isotherm upon rehydration after drying at intermediate moisture levels. Thus, adsorbing seeds of these species have greater longevity than desorbing seeds at the same RH. In contrast, seeds of oilseed rape and yellow mustard do not show a hysteresis effect unless they are dried to very low MC (over silica gel), so the adsorbing seed longevity remains the same as desorbing seeds at a constant RH. It is important to consider the moisture history of seeds depending on species for better seed storage management.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"109 ","pages":"Article 102477"},"PeriodicalIF":2.7,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654782","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}

Currently, the detection of these pests relies on manual counting, a method that is both time-consuming and labor-intensive. Given the limitations of hardware equipment, developing a model that is both easy to deploy and lightweight is especially crucial. To address this need, a new model based on the YOLOv8n architecture, named YOLO-TP, has been specially designed and introduced. The model incorporates the Grouped Shuffle Convolution (GSConv) and an optimized new PC2f structure with Partial Convolution (PConv), aimed at reducing redundant channel computations. Additionally, by employing the Generalized Intersection over Union (GIoU) loss function, it collectively achieves the goals of performance optimization and model lightweighting. YOLO-TP has achieved a high accuracy rate of 99.5% on the tobacco beetle dataset, while simultaneously reducing model parameters and computational requirements by 57.81% and 46.34%, respectively.

Optimization studies using a Box-Behnken design showed that initial pH significantly affected AFB1 degradation, with the optimal conditions identified as pH 7, 25 °C, and 24 h of incubation, resulting in approximately 90% AFB1 degradation. Additionally, <em>P. knackmussii</em> AD02 simultaneously degraded a mixture of AFB1, AFB2, AFG1, and AFG2. A mechanistic study of AFB1 degradation revealed the role of extracellular enzymes, particularly in proteinaceous and membrane-associated components. The mechanism for AFB1 degradation involved the hydrolytic cleavage of the lactone ring in the coumarin moiety, followed by the cleavage of the cyclopentenone ring and the elimination of double bonds in the furan and coumarin moieties. The <em>in silico</em> predictions indicated that this bacterium could metabolize AFB1 into a non-mutagenic and non-carcinogenic intermediate product.

The search for new grain protectants is critical because of the propensity of <em>R. dominica</em> to develop genetic resistance to various insecticides such as organophosphates (OPs), carbamates, synthetic pyrethroids and juvenile hormone analogues. Wheat was treated with 0, 60, 90 or 120 ppm of flavesone as it passed through an auger into large (1 tonne) storage bags. The treated wheat was stored for 13 months under sheltered ambient conditions in southeast Queensland, and samples were also collected 1 week after treatment and stored for 13 months in the laboratory at 30 °C and 55% RH for comparative purposes. Bioassays of wheat stored under laboratory and ambient conditions, showed that an application rate of 60 ppm provided protection for at least 13 months from a susceptible strain, based on high levels of suppression of the F₁ generation. Untreated wheat stored under ambient conditions became heavily infested with <em>R. dominica</em>, while none were detected in any of the treatments, thus further confirming the potential of flavesone as an effective grain protectant. However, bioassays showed that the 60-ppm rate only provided 3 months protection from a strain that was resistant to OPs and pyrethroids, indicating potential non-target site resistance present in this strain. Higher application rates of 90 and 120 ppm were required for 13 months protection. As reported in some other grain protectant studies, initial flavesone residues were lower than the targeted rates, suggesting potential for improving formulation and application methods. Flavesone residues remained relatively stable throughout the study period.
