The present study evaluates the life table, functional and numerical response of Blaptostethus pallescens (Poppius) when reared on three different factitious preys: Tyrophagus putrescentiae (Schrank), Corcyra cephalonica (Stainton), and Phthorimaea operculella (Zeller). Significant variation was observed in developmental time, adult longevity, and reproductive parameters across the three diets. Individuals fed on T. putrescentiae exhibited prolonged pre-adult development and reduced adult longevity and fecundity compared to those fed on lepidopteran eggs. Female fecundity was highest on C. cephalonica and P. operculella eggs, while lowest on T. putrescentiae. Life table analysis revealed that the intrinsic rate of increase (r) was significantly lower on T. putrescentiae, indicating suboptimal population growth, whereas lepidopteran egg diets promoted higher reproductive and population parameters. Functional response analysis confirmed a type II response across all prey, with the highest attack rate (3.5 h⁻¹) and shortest handling time (0.0079 h) recorded on T. putrescentiae. Despite lower fecundity, T. putrescentiae supported full development and survival of B. pallescens, suggesting its potential as a factitious prey in mass rearing systems. This predator completed its life cycle inside breadboxes containing wheat bran and yeast, indicating feasibility for use in predatory sachets. These findings support the use of B. pallescens in biological control programs, particularly in greenhouse systems, where cost-effective and locally adaptable rearing methods are urgently needed. The study also highlights the promise of T. putrescentiae as a prey species for slow-release systems, offering a practical solution for enhancing macrobial biocontrol strategies in India. Although T. putrescentiae is known to produce allergens, the adoption of simple safety measures, such as wearing masks and gloves can effectively minimize any associated risks during handling or rearing.

本研究评估了三种不同的人工饵料：腐Tyrophagus purescentiae （Schrank）、头颈Corcyra cephalonica （Stainton）和有盖Phthorimaea operculella （Zeller）饲养时，灰鳞Blaptostethus pallescens （Poppius）的生命表、功能和数值反应。三种饮食在发育时间、成虫寿命和生殖参数上观察到显著差异。与以鳞翅目卵为食的个体相比，以腐翅虫为食的个体表现出较长的成虫前发育时间和较短的成虫寿命和繁殖力。雌虫的产卵能力以头孢丝虫和盖孢丝虫的卵最高，而以腐殖丝虫的卵最低。生命表分析显示，腐斑蝶的内在增长率(r)明显较低，表明种群增长不理想，而鳞翅目的卵饮食促进了更高的繁殖和种群参数。功能反应分析证实所有猎物均为II型反应，腐尸的攻击率最高（3.5 h−1），处理时间最短（0.0079 h）。尽管繁殖力较低，但腐尸螟支持白僵菌的完全发育和存活，表明其在大规模饲养系统中有作为人工猎物的潜力。这种捕食者在含有麦麸和酵母的面包盒中完成其生命周期，这表明在捕食小袋中使用的可行性。这些发现支持在生物防治计划中使用白僵菌，特别是在温室系统中，迫切需要具有成本效益和适合当地的饲养方法。该研究还强调了腐尸霉作为缓释系统猎物的前景，为加强印度的微生物生物防治策略提供了切实可行的解决方案。虽然已知腐殖弓形虫会产生过敏原，但采取简单的安全措施，如戴口罩和手套，可以有效地减少处理或饲养过程中的任何相关风险。

This study investigated the tritrophic interactions among legume host plants, the bruchid pest Callosobruchus maculatus, and its parasitoid Dinarmus basalis, emphasizing the effects of biochemical composition on parasitoid performance. C. maculatus strains developing on protein and carbohydrate rich seeds were associated with higher body weight, large size, and improved biological parameters, including longevity, adult emergence rates, and fertility. Female fecundity and egg viability in C. maculatus were positively correlated with larval protein and carbohydrate intake, reflecting the quality of the host seed resource. Parasitoid fitness, essential for effective biological control of host populations, depends critically on substantial protein, lipid, and carbohydrate acquisition for survival and reproductive success. Our focus was specifically on the correlations between adult parasitoid life history parameters and host biochemical composition. The sugar content of fourth-instar C. maculatus larvae significantly influenced parasitoid performance, with a notable positive relationship between larval sugar concentration and D. basalis sex ratio bias toward females. This represents the first comprehensive investigation of relationships between the biochemical composition of C. maculatus L4 larvae and the biological and demographic performance of its parasitoid D. basalis. Our results demonstrate that macronutrient content in both plant hosts and herbivorous pests plays a crucial role in determining the strength and outcomes of tritrophic interactions.

本研究研究了豆科寄主植物、毛糙蛾及其拟寄生物基底螯蟹之间的营养相互作用，重点研究了生化组成对拟寄生物性能的影响。在富含蛋白质和碳水化合物的种子上发育的黄斑弧菌菌株具有更高的体重、更大的体型和更好的生物学参数，包括寿命、成虫羽化率和繁殖力。黄斑夜蛾的雌虫繁殖力和卵活力与幼虫蛋白质和碳水化合物摄入量呈正相关，反映了寄主种子资源的质量。拟寄生物的适应性对寄主种群的有效生物控制至关重要，它主要依赖于大量蛋白质、脂质和碳水化合物的获取，以维持生存和繁殖成功。我们的重点是研究成虫生活史参数与寄主生化组成的相关性。4龄黄斑夜蛾幼虫含糖量对寄生蜂的寄生性能有显著影响，且含糖量与基底夜蛾的雌偏性率呈显著正相关。这是第一次全面研究斑夜蛾L4幼虫的生化组成与其寄生蜂基底夜蛾的生物学和人口统计学表现之间的关系。我们的研究结果表明，植物宿主和草食性害虫体内的宏量营养素含量在决定营养相互作用的强度和结果方面起着至关重要的作用。

Varietal resistance in cereals represents a promising and sustainable strategy for managing biotic stressors, including insect pests during storage. In this study, eighteen genotypes from six cereal species - Triticum monococcum, T. dicoccum, T. spelta, T. durum, T. aestivum, and Triticosecale - were evaluated for their resistance to the rice weevil, Sitophilus oryzae L., one of the most destructive stored product pests. The objective was to assess differences in susceptibility by measuring some insect parameters, such as adult mortality, F1 progeny production and body size, along with grain traits such as kernel hardness and weight. For this scope, bioassays included both non-choice and two-way choice tests to evaluate insect performance and preference. Significant inter- and intra-specific variation in susceptibility was observed. In non-choice bioassays, Sitophilus oryzae generally showed higher adult mortality and lower adult progeny emergence feeding and ovipositing on T. durum and T. dicoccum genotypes, suggesting greater resistance of these genotypes; on the contrary T. monococcum and triticale appear more susceptible. Grain hardness was strongly and negatively correlated with adult progeny output, supporting its role as a mechanical barrier to larval development. However, kernel hardness did not influence adult body size, suggesting that individuals overcoming this barrier can still complete normal development. Kernel weight showed a positive correlation with female size, indicating a potential fitness advantage for the insects feeding on larger seeds. In two-choice assays, S. oryzae showed a preference for softer genotypes, particularly triticale Agostino and Tribeca, over harder genotypes such as durum wheat Perciasacchi and Aureo. These results provide new insights into the resistance potential of traditional and modern Triticum genotypes. The integration of resistant genotypes, especially from T. durum and T. dicoccum, into breeding programs and storage systems may contribute to reducing chemical inputs and improving long-term grain protection strategies.

谷物的品种抗性是一种有前途的可持续策略，可用于管理生物应激源，包括储存期间的害虫。本研究对6种谷物（单粒小麦、双粒小麦、粗粒小麦、硬粒小麦、aestivum小麦和小黑麦）18个基因型对稻谷象甲（稻谷象甲是最具破坏性的储藏产品害虫之一）的抗性进行了评价。目的是通过测量一些昆虫参数，如成虫死亡率、F1后代产量和体型，以及籽粒硬度和重量等谷物性状，来评估敏感性的差异。在这个范围内，生物测定包括非选择试验和双向选择试验，以评估昆虫的性能和偏好。观察到显着的种间和种内易感性差异。在非选择性生物测定中，米象蚜对硬粒稻和二粒稻均表现出较高的成虫死亡率和较低的成虫后代羽化、摄食和产卵，表明这两种基因型对米象蚜具有较强的抗性；相反，单球菌和小黑麦更易感染。籽粒硬度与成虫子代产量呈显著负相关，支持其作为幼虫发育的机械屏障的作用。然而，果仁硬度并不影响成虫的体型，这表明克服这个障碍的个体仍然可以完成正常的发育。籽粒重与雌虫体型呈正相关，表明以较大的种子为食的昆虫具有潜在的适应性优势。在两种选择试验中，稻谷球菌表现出对软基因型的偏爱，特别是小黑麦Agostino和Tribeca，而不是硬基因型，如硬粒小麦Perciasacchi和Aureo。这些结果为传统和现代小麦基因型的抗性潜力提供了新的见解。将抗性基因型，特别是来自硬粒稻和二粒稻的抗性基因型整合到育种计划和储存系统中，可能有助于减少化学品投入和改善长期粮食保护策略。

This study was conducted to examine the impact of commercial phosphine fumigation on survival and progeny of natural free-living insect populations in wheat and maize stored in concrete silos. Aluminium phosphide pellets (560 g/kg) were applied at the recommended dose of 20–25 pellets/t of grains (4–5 g of phosphine gas/t) in two airtight cells in one silo at Pančevo locality (wheat and maize) and in one without airtight cell, in silos in Perlez (wheat) and Vrbas (maize). Samples collected before fumigation were used for pre-treatment assessment of grains' infestation levels, while samples taken for post-treatment assessment served to determine insect survival after 4 weeks and progeny after 8, 12 and 16 weeks. All taken samples were kept and analysed in laboratory. In pre-treatment assessment of wheat we found two primary and three secondary pests in density rates 0–0.9 and 1-34 adults/sample/kg, respectively. In maize were recorded one primary and three secondary pests in rates 1.5–1.7 and 0.9–62 adults/sample/kg, respectively. Post-treatment assessments of treated grains showed no insect survival and progeny. However, in untreated grains we recorded population growth of all insect species, especially of primary pests, Rhyzopertha dominica (F.) in wheat in Pančevo, from 0 to 170.4 adults/kg, and Sitophilus zeamais (Motsch.), in maize in Pančevo from 1.5 to 82.6 adults/kg and in Vrbas from 1.7 to 74.9 adults/kg. The phosphine gas high impact on survival and progeny of all recorded natural free-living insects, regardless of grain and storage type is promising for its further use in the future.

本研究旨在研究商业磷化氢熏蒸对混凝土筒仓储存的小麦和玉米自然自由生活昆虫种群的存活和后代的影响。磷化铝颗粒（560 g/kg）按20-25粒/吨谷物（4-5克磷化气/吨）的推荐剂量施用于pan evo地区（小麦和玉米）一个仓内的两个密闭仓内和Perlez（小麦）和Vrbas（玉米）仓内的一个不密闭仓内。熏蒸前采集的样品用于处理前评估谷物侵染水平，处理后评估的样品用于测定4周后的昆虫存活率和8、12和16周后的后代。所有采集的样品均保存在实验室进行分析。在小麦处理前评估中，主要害虫2只，次要害虫3只，密度率分别为0 ~ 0.9和1 ~ 34只/样/kg。在玉米中主要害虫1只，次要害虫3只，危害率分别为1.5 ~ 1.7和0.9 ~ 62只/样/kg。处理后的评估显示，处理后的谷物没有昆虫存活和后代。然而，在未经处理的谷物中，我们记录了所有昆虫的种群增长，特别是主要害虫，在pan evo小麦中的Rhyzopertha （F.）在0到170.4成虫/kg之间，在pan evo玉米中的玉米象（Motsch.）在1.5到82.6成虫/kg之间，在Vrbas中在1.7到74.9成虫/kg之间。磷化氢气体对所有有记录的自然自由生活昆虫的生存和后代都有很高的影响，无论粮食和储存类型如何，它在未来的进一步利用是有希望的。

Insect infestations in stored grain systems pose a significant threat to global food security by reducing both the quality and quantity of cereals. Sitophilus zeamais, the maize weevil, is one of the most destructive pests affecting stored cereals worldwide. While synthetic chemicals are commonly used for control, concerns regarding environmental safety, human health and the emergence of insecticide resistance have intensified the search for alternative control strategies. Essential oils and their constituents have emerged as promising eco-friendly alternatives. In this study, we evaluated the behavioural responses of S. zeamais to three isolated high-purity essential oil-derived compounds – 1,8-cineole, (S)-(−)-Limonene, and Eugenol – using a four-arm olfactometer. Adult S. zeamais were exposed to different concentrations of each compound, and repellence was inferred from the time spent in the central or distal zones of the olfactometer. The essential oil-derived compounds tested demonstrated promising repellent properties against weevils, as the insects spent more time away from the source or remained in the central region of the device, indicating repellent activity. Our findings contribute to the expanding body of research on botanical pest control methods and underscore the potential of these compounds to support the development of sustainable and environmentally friendly pest management strategies. These approaches can reduce dependency on synthetic chemicals while effectively limiting post-harvest losses in stored grains.

储粮系统中的虫害降低了谷物的质量和数量，对全球粮食安全构成重大威胁。玉米象甲（Sitophilus zeamais）是影响全球储藏谷物的最具破坏性的害虫之一。虽然合成化学品通常用于控制，但对环境安全、人类健康和杀虫剂抗药性出现的关切促使人们加紧寻找其他控制战略。精油及其成分已成为有希望的环保替代品。在这项研究中，我们使用四臂嗅觉仪评估了玉米玉米对三种分离的高纯度精油衍生化合物- 1,8-桉叶油素，(S)-(−)-柠檬烯和丁香酚-的行为反应。将玉米玉米螟成虫暴露于不同浓度的化合物中，并根据其在嗅觉仪中心或远端区域停留的时间推断出其驱避性。经测试的精油衍生化合物显示出对象鼻虫有良好的驱避性能，因为昆虫在远离源或留在装置的中心区域的时间更长，表明驱避活性。我们的发现有助于扩大植物害虫控制方法的研究范围，并强调这些化合物的潜力，以支持可持续和环境友好型害虫管理策略的发展。这些方法可以减少对合成化学品的依赖，同时有效地限制储存谷物的收获后损失。

Timely and accurate pest detection in grain storage environments is essential for safeguarding food security. Traditional detection methods face significant challenges in efficiently and precisely identifying small pests. This study presents Pest-YOLO, a lightweight detection model based on YOLOv8n, specifically designed for stored grain pest identification. The model incorporates an Efficient Feature Enhancement Module (EFEM) that efficiently captures pixel-level details while reducing computational redundancy. A Detail-Enhanced YOLO Head (DEYH) is designed to improve computational efficiency through shared convolutional layers. Furthermore, an Attention-Based Intra-Scale Feature Interaction (AIFI) module is integrated into the backbone network to enhance global feature interactions, improving the overall fine-grained feature extraction capability. Additionally, the network structure is optimized by introducing a P2 detection layer while removing the P5 layer, thereby enhancing small-object detection accuracy while reducing computational overhead. The model was trained and evaluated on a custom Stored Grain Pest 5 (SGP5) dataset containing 8000 images of five common pest species. Experimental results demonstrate that Pest-YOLO achieves 95.0 % precision and 93.6 % recall, with mAP_0.5 and mAP_0.5:0.95 reaching 97.5 % and 60.0 %, respectively. With only 1.3M parameters and 4.7G FLOPs, the model demonstrates superior computational efficiency while maintaining high detection accuracy. When deployed on the NVIDIA Jetson Orin Nano edge computing platform, Pest-YOLO achieves real-time inference at 36.2 FPS, validating its practical applicability in resource-constrained environments. This research provides a practical solution for intelligent grain storage management and accurate pest identification.

在粮食储存环境中及时、准确地检测有害生物对保障粮食安全至关重要。传统的检测方法在有效、准确地识别小害虫方面面临重大挑战。本研究提出了一种基于YOLOv8n的轻量化检测模型pest - yolo，专门用于储粮害虫鉴定。该模型采用高效特征增强模块（EFEM），有效捕获像素级细节，同时减少计算冗余。细节增强YOLO Head （DEYH）通过共享卷积层来提高计算效率。此外，在骨干网中集成了基于注意力的尺度内特征交互（AIFI）模块，增强了全局特征交互，提高了整体细粒度特征提取能力。此外，通过在去掉P5层的同时引入P2检测层来优化网络结构，从而在提高小目标检测精度的同时降低了计算开销。该模型在一个定制的存储谷物害虫5 （SGP5）数据集上进行训练和评估，该数据集包含5种常见害虫的8000张图像。实验结果表明，Pest-YOLO的准确率为95.0%，召回率为93.6%,mAP0.5和mAP0.5:0.95分别达到97.5%和60.0%。该模型仅使用1.3M个参数和4.7G FLOPs，在保持较高检测精度的同时，具有优越的计算效率。当部署在NVIDIA Jetson Orin Nano边缘计算平台上时，Pest-YOLO实现了36.2 FPS的实时推理，验证了其在资源受限环境中的实际适用性。本研究为粮食仓储智能化管理和害虫准确识别提供了切实可行的解决方案。

Soybean is one of the main oilseeds cultivated worldwide, distinguished by its high protein and oil content. However, the quality of the grains can be compromised by inadequate drying conditions and excessive moisture levels. Elevated temperatures may cause structural damage and accelerate oxidative reactions, whereas excess moisture promotes enzymatic activity and fungal development. This study thoroughly evaluated the impact of different air temperatures (40 °C, 50 °C, and 60 °C) applied during stationary drying, as well as varying moisture content levels (12 % and 14 %), on the overall quality of soybeans stored in a semi-hermetic system for a duration of 12 months. It was observed that higher drying temperatures combined with elevated moisture content significantly increased oil acidity, electrical conductivity, and the incidence of both physical and fungal defects. These adverse conditions also led to a reduction in grain-specific mass, soluble proteins, and leached solids. Furthermore, the chemical composition and colorimetric profile of the soybeans were negatively affected, with greater losses of lipids and proteins in grains stored at the higher moisture level. The colorimetric profile indicated grain darkening, which was more pronounced at 12 months of storage and when drying temperatures of 50 or 60 °C were applied. Drying at 40 °C and lowering moisture to 12 % proved to be more effective in preserving the technological, sanitary, and visual quality of the soybeans. These findings emphasize the critical importance of proper drying and moisture control strategies to maintain product quality throughout storage.

大豆是世界上种植的主要油料种子之一，其特点是蛋白质和油脂含量高。然而，谷物的质量可能会因干燥条件不充分和湿度过高而受到损害。高温可能会造成结构破坏并加速氧化反应，而过多的水分则会促进酶的活性和真菌的生长。本研究全面评估了固定干燥过程中不同空气温度（40°C、50°C和60°C）以及不同含水量水平（12%和14%）对在半封闭系统中储存12个月的大豆整体质量的影响。研究发现，较高的干燥温度和较高的水分含量显著增加了油的酸度、电导率以及物理和真菌缺陷的发生率。这些不利条件也导致颗粒特异性质量、可溶性蛋白质和浸出固体的减少。此外，大豆的化学成分和比色谱也受到负面影响，在较高水分条件下储存的籽粒中脂肪和蛋白质的损失更大。比色谱显示，在储存12个月和干燥温度为50或60°C时，颗粒变暗更为明显。在40°C下干燥并将水分降至12%被证明在保持大豆的技术、卫生和视觉质量方面更有效。这些发现强调了适当的干燥和湿度控制策略在整个储存过程中保持产品质量的重要性。

This study investigated the effects of chitosan-ginger essential oil coatings on the preservation of maize seeds during storage. The coating significantly enhanced the seed's antifungal protection, antioxidant defense mechanisms and germination potential. Maize seeds subjected to chitosan and ginger essential oil treatment showed significantly reduced insect damage (5 % vs. 32 % in control), fungal contamination (8 % vs. 36 %), and aflatoxin B1 levels (4.7 ppb vs. 28.5 ppb) relative to untreated seeds. The coating treatment resulted in decreased malondialdehyde (MDA) levels (2.3 nmol/g vs. 6.2 nmol/g), signifying reduced oxidative stress, and maintained a high germination rate (92 % after 12 months vs. 75 % in control). These findings demonstrate that the chitosan-ginger essential oil coating sustainably enhanced the quality of stored maize seeds, with the combination showing an effect greater than either component alone, offering practical and ecological advantages.

研究了壳聚糖-姜精油包衣对玉米种子贮藏保鲜的影响。包衣能显著增强种子的抗真菌保护、抗氧化防御机制和萌发潜力。经壳聚糖和生姜精油处理的玉米种子与未处理的种子相比，昆虫损害（5%比对照组32%）、真菌污染（8%比36%）和黄曲霉毒素B1水平（4.7 ppb比28.5 ppb）显著降低。包衣处理降低了丙二醛（MDA）水平（2.3 nmol/g vs. 6.2 nmol/g），表明氧化应激降低，并保持了较高的发芽率（12个月后为92%，对照组为75%）。综上所述，壳聚糖-姜精油包衣可持续性地提高玉米种子贮藏质量，且复合包衣效果优于单独包衣，具有实用和生态优势。

The groundnut bruchid (Caryedon serratus) is a major storage pest of groundnut pods and kernels. Despite its economic significance, this species' sensilla morphology remains poorly studied, limiting the development of reliable control measures. This study presents a detailed morphological, ultrastructural, and molecular characterization of C. serratus, emphasizing the types and distribution of sensilla. Adults are greyish brown, sexually dimorphic in size and structure, with golden setae, a reddish integument, and scattered dark spots. The reniform compound eyes comprise hexagonal, pentagonal, and irregularly shaped ommatidia interspersed with interfacial hairs. The serrated 11-segmented antennae, as well as the labial and maxillary palpi, are equipped with diverse sensilla, including Böhm bristles (BB), trichoid (ST), chaetica (SC), basiconica (SB), coeloconica (SCo), styloconicum (STy), cavity (SCa), twig basiconica (STB), and glandular structures (cuticular pores, perforated plates). These indicate a multifunctional sensory system. The elytra possess numerous circular to oval glandular pits associated with sensilla. A key taxonomic feature is the presence of eleven metafemoral teeth on the hind leg, divided by a blunt projection bearing ST-type sensilla. Molecular analysis of the mitochondrial COI gene revealed a single 650 bp band, showing 100 % similarity with existing sequences in the NCBI database. This is the first detailed report on the sensilla morphology of C. serratus, laying the foundation for further research on insect behavior and the development of semiochemical-based pest management strategies.

花生鼩鼱（Caryedon serratus）是花生荚和籽粒的主要贮藏害虫。尽管具有经济意义，但该物种的感受器形态学研究仍然很少，限制了可靠控制措施的发展。本文详细介绍了锯齿木的形态、超微结构和分子特征，重点介绍了感受器的类型和分布。成虫是灰褐色的，两性在大小和结构上是二形的，有金色的刚毛，红色的被毛，和分散的黑点。肾形复眼包括六角形、五角形和不规则形状的点缀着界面毛的小眼。锯齿状的11节段触角，以及唇部和上颌触须，具有多种感受器，包括Böhm刚毛（BB）、毛状（ST）、毛状（SC）、基状（SB）、腔状（SCo）、茎尖（STy）、腔（SCa）、小枝基状（STB）和腺体结构（角质层孔、穿孔板）。这表明这是一个多功能的感觉系统。鞘翅上有许多圆形到椭圆形的腺窝，与感受器相连。一个关键的分类学特征是后腿上有11颗后股骨牙齿，由一个带有st型感受器的钝突牙划分。对线粒体COI基因进行分子分析，发现单个650 bp的条带，与NCBI数据库中现有序列的相似性为100%。本文首次详细报道了锯齿锥蝽（C. serratus）的感觉器官形态，为进一步研究昆虫行为和开发基于半化学的害虫防治策略奠定了基础。

The objective of the research was to evaluate the integrated effects of different drying temperatures, grain moisture contents, and storage temperatures over twelve months of soybean storage. The harvested grains were dried at 40 °C and 60 °C in a fixed-bed dryer, under a stationary system, to moisture contents of 12 % and 14 %, and then stored at 16 °C (refrigerated) and 28 °C (ambient). Physical, chemical, and microbiological parameters were evaluated. Samples dried at 40 °C to 12 % moisture and stored under refrigeration (16 °C) showed better preservation of quality. Higher drying temperature (60 °C) and higher grain moisture content (14 %) under storage at 28 °C resulted in the greatest deterioration rates after one year of storage. DSC analysis revealed changes in thermal properties among the different treatments. Fungal incidence indicated a reduction of field fungi and an increase in storage fungi, especially those resistant to higher temperatures in grains with 14 % moisture. Drying and storage conditions influenced grain quality over time. The combination of lower moisture content (12 %), mild drying temperature (40 °C), and refrigerated storage (16 °C) promoted better preservation during storage, maintaining chemical and microbiological characteristics and minimizing degradation, thus reinforcing the importance of appropriate drying and storage practices for grain conservation.

本研究旨在评价不同干燥温度、籽粒含水量和贮藏温度对大豆贮藏12个月的综合影响。收获的谷物在固定床干燥机中，在固定系统下，在40°C和60°C下干燥至12%和14%，然后在16°C（冷藏）和28°C（环境）下储存。评估了物理、化学和微生物参数。样品在40°C至12%的湿度下干燥，并在冷藏（16°C）下储存，可以更好地保存质量。较高的干燥温度（60°C）和较高的28°C贮藏条件下的籽粒含水率（14%）导致贮藏1年后的腐坏率最高。DSC分析显示了不同处理之间热性能的变化。真菌发病率表明田间真菌减少，储藏真菌增加，特别是那些在14%水分条件下耐高温的谷物。随着时间的推移，干燥和储存条件会影响谷物的品质。较低的水分含量（12%）、温和的干燥温度（40°C）和冷藏（16°C）的组合促进了贮藏过程中的更好保存，保持了化学和微生物特性，并最大限度地减少了降解，从而加强了适当的干燥和储存方法对粮食保存的重要性。
