Whole fuzzy cottonseed, a byproduct of cotton gins, undergoes various processes to extract oil and produce meal and hulls. These are either used as animal feed or soil amendments. However, aflatoxin contamination poses significant challenges due to strict FDA action levels for dairy and beef cattle feed. This contamination occurs when <em>Aspergillus flavus</em> infects crops under specific environmental conditions or through improper handling during post-harvest processes. Our research aims to document aflatoxin levels during each stage of post-harvest processing, from cleaning to meal formation. Preliminary findings suggest that certain stages may concentrate aflatoxins akin to other agricultural products like dried distillers’ grains and solubles (DDGS). The implications of these findings could be profound for the dairy industry, where low allowable aflatoxin levels impact both economic and animal health outcomes. The cottonseed post-harvest process consists of cleaning, delinting, hull removal, kernel flaking, oil extraction, and meal formation. Understanding how aflatoxin levels change during these steps is crucial for ensuring safe and high-quality defatted cottonseed meal for livestock consumption. Microbial levels increased by 4 orders of magnitude during the acid delinting process, from 7.0× 10⁵ to 5.2 × 10⁹ CFU/g, and 5 orders of magnitude during the mechanical delinting process, from 7.3× 10⁵ to 1.5 × 10¹⁰ CFU/g for the inoculated cottonseed samples. Higher microbial load was associated with lower protein levels and lower fat acidity levels. Further research will shed light on the effects of aflatoxin concentration on the nutritional value of the final product.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141481545","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}

Laboratory experiments were conducted to determine the grain preference of various landrace and commercial rice genotypes to rice weevil. <em>S. oryzae</em>, findings divulged the low rates of adult emergence, low rates of grain consumption and high rates of mortality in the grain of rice varieties, HUR-3022 and Nagina-22.

Among the various physical characteristics investigated, grain hardness was found to have a significant and negative correlation with alive insect, grain weight loss, and preference index. On the other hand, protein and other biochemical grain characteristics were found to have a positive correlation with insect emergence, weight loss, and preference index. In particular, amylose (a key grain component) was found to have a negative correlation with weight loss and insect emergence. The findings of this study suggest that screening of different rice genotypes, for determining grain preference, may be a more viable option to minimize the grain losses during storage caused by <em>S. oryzae.</em> Moreover, the findings of present study could also help to formulate the breeding programs aimed at developing cultivars resistant to this notorious pest.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141481546","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 work aimed to evaluate the physical and physiological quality of soybean seeds submitted to IST, with subsequent storage in a natural and controlled environment. The experiment was conducted in a split-split-plot design in a completely randomized scheme (time x storage systems x IST) with four replications. Soybean cultivar 55I57RSF IPRO was subjected to IST with fungicide (metalaxyl-M, thiabendazole, and fludioxonil) and insecticide (thiamethoxam and cyantraniliprole), combined or not with polymer and dry powder, with subsequent storage in a controlled and natural environment. The moisture content, thousand-seed weights, germination, first germination count, germination speed index, accelerated aging, seedling length, dry matter transfer, and emergence sand test were evaluated. IST did not affect the moisture content and weight of a thousand seeds. However, storage in a controlled environment provided a greater reduction in moisture content and a smaller reduction in the weight of a thousand seeds. IST negatively affected germination, first germination count, germination speed index, and accelerated aging test. IST negatively affected plant length, except in the treatment where only insecticide was applied. The dry mass transfer was negatively affected but with less intensity in seeds subjected only to the application of insecticide or fungicide and the combination of insecticide, fungicide, and polymer. Seed emergence in the sand was negatively affected by all treatments. Regardless of the treatments, all responses evaluated showed a reduction throughout storage, with greater intensity in seeds stored in the natural environment.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141444482","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}

Various stressors can instigate prolonged diapause among insect larvae, increasing the challenge of managing infestation. When the environmental conditions become conducive to development, diapause ceases, and the larva progresses on its developmental course. Members of the Heat Shock Protein (HSP) family play a significant role in protecting insects from the impacts of environmental stressors. In this study, six small heat shock proteins (TsHSP19.8, TsHSP20.5, TsHSP20.6, TsHSP20.8, TsHSP21.2, and TsHSP21.3) were identified and characterized in <em>T. granarium</em>.
