This study aimed to evaluate the postharvest application of plant-derived citral and thymol-based shellac wax coatings on ‘Kinnow’ mandarin under controlled conditions (5–7 °C, 90–95 % relative humidity (RH)) over a 75-day storage period. The fruit were coated with shellac wax (SH) supplemented with citral (1.0 %, CSH), thymol (1.0 %, TSH) and citral-thymol combined formulation (1.0 %, CTSH (1:1)). Rheology studies revealed that the Herschel–Bulkley model was the best fit for all coating solutions, ensuring desirable spreadability and adhesion. The CTSH-coating outperformed all other treatments by reducing mean spoilage to 0.46% as compared to commercial shellac (6.71%) over a period of 75 days under cold store conditions. The treated fruit could control the physiological weight loss to 5.73 % as compared to commercial SH coatings (7.62 %) for 60 days. The study concluded that CTSH-coated Kinnow fruit can be stored up to 60 days under cold store conditions at 5–7 °C and 90–95 % RH with acceptable fruit quality (sensory score 7.83). The activities of cell wall degrading enzymes such as Pectin methylesterase (PME) and cellulase were also found to be retarded, contributing to prolonged shelf life. Therefore, these coatings may offer a green substitute to the synthetic analogues, with no health side effects for extending the postharvest shelf life of Kinnow up to 60 days under cold store conditions.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142233819","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}

Argentina is one of the main producers and exporters of corn globally. Post-harvest pests, such as the insect <em>Sitophilus zeamais</em>, can cause losses of more than 10%, representing a very important negative economic impact on the industry. For pest control many synthetic insecticides are used. Nevertheless, these insecticides show toxicity to mammals and environmental contamination and cause resistance. For this, there is a constant need to introduce new substances used in the protection of crops and the plant extracts and their volatile products are an interesting alternative. In this work we evaluate the effectiveness of natural VACs for the control of <em>S. zeamais</em> and the prolonged effect of the more toxic alcohol incorporated in a paint on its survival. 1-heptyn-3-ol was the most toxic alcohol tested (LC₅₀ = 0.74 μL/L). In the presence of food, the fumigant toxicity of 1-heptyn-3-ol was lower (LC₅₀ = 14.73 μL/L). Also, the non-phytotoxic effect of 1-heptyn-3-ol was determined. When the 1-heptyn-3-ol was included in the polyvinyl paint, the toxic effect was prolongated in the time, causing even 80% mortality at 14th day. Regarding the repellent effect of 1-heptyn-3-ol, it was observed that this alcohol included in the bioactive paint, in the presence of food, presented a repellency similar to that determined for the pure compound, in the absence of food, and greater than the repellency determined for the pure compound in the presence of food. In conclusion, compounds such as 1-hetpyn-3-ol is a potential candidate for insecticidal formulations that allow adequate management of <em>S. zeamais</em> in stored grain. This study presents a preliminary design of a biopaint with insecticidal and repellent activity against the pest insect <em>S. zeamais.</em></p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232023","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}

A novel preventative integrated pest management (IPM) tactic to intercept dispersing insects of durable commodities (e.g., packaged goods, flour, bulk commodities), is a long-lasting insecticide-incorporated netting (LLIN) containing 0.4% deltamethrin. However, it is unknown how exposure to the deltamethrin-based LLIN (LLIN hereafter) may affect olfaction and orientation to important semiochemicals by stored product insects. In this study, our aims were to evaluate whether exposure to LLIN affected male and female (or mixed sex) populations of <em>Trogoderma variabile</em> and <em>T. inclusum</em> movement in the presence of important semiochemicals, including food kairomones and pheromones, including the major sex pheromone for <em>Trogoderma</em> spp. (e.g., (<em>Z</em>)-14-methyl-8-hexedecenal). We evaluated this with a video-tracking protocol and confirmed volatile emissions with headspace collection coupled with gas chromatography and mass spectrometry (GC/MS). Disruption in movement in this study is taken to mean a significant upregulation or downregulation in response compared to our netting without active ingredient (control). Distance moved increased 4–6-fold in <em>T. variabile</em> after exposure to LLIN compared to control netting, while it was reduced by a third to a half in <em>T. inclusum</em>. Overall, out of 40 possible olfactory and taxis patterns which could be disrupted, exposure to LLIN interrupted 68–73% of these in <em>T. inclusum</em> and <em>T. variabile</em>, respectively, compared to control netting-exposed individuals. Pheromonal stimuli were more important for males, but food and pheromones were equally important for females.

Rapid and effective pest control is the key to minimise damage to the valuable grain. The current study investigated the efficiency of a farm-scale thermosyphon silo to passively circulate phosphine fumigant gas by measuring the phosphine concentrations at a series of points throughout the silo. A 50 tonne sealable grain silo with an external thermosyphon was fitted with gas sampling lines at three different levels in the grain body, and also in the headspace. The grain was fumigated with phosphine gas 12 times over a 12 month period to contrast the thermosyphon system efficiency under varied external environmental conditions. The minimum fumigation standards of 200 ppm for 10 days or 300 ppm for 7 days were reached and exceeded in all fumigation cycles throughout the year in 12.5–22 days, demonstrating the effectiveness of the thermosyphon system. In addition, the final fumigation was held until the phosphine concentration dropped to 200 ppm. The silo reached 200 ppm only four days after fumigation, reached a maximum of approximately 600 ppm after 30 days, and did not fall below 200 ppm until 106 days after fumigation. Linear air velocity in the was also measured in the thermosyphon pipe and showed that airflow could reach as high as 2.7 m/s, but flow was sporadic and not consistent, most likely due to pressure build up on the headspace of the silo due to resistance to airflow by the bulk grain body. Temperature and humidity results indicated that while both parameters are fundamental in the production of phosphine from aluminium phosphide tablets, they work against each other. This provides an effective control mechanism that prevents the rapid production of phosphine, thereby reducing the buildup of phosphine and reducing the risk of an explosion.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0022474X24001711/pdfft?md5=72eac020e0dec125a88faa4e39cdec91&pid=1-s2.0-S0022474X24001711-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142168629","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}

This study aims to explore the effect of radiofrequency low-pressure cold plasma (RF-CP) processing on cashew nuts, using four gas combinations: Nitrogen (N₂), Argon (Ar), N₂+O₂, and Ar + O_2. Dried cashew nut kernels underwent RF-CP treatment at six different power options (60, 90, 120, 150, 180, and 210 W), at four distinct time (5, 10, 15, and 20 min). Following the treatment, the samples underwent proximate analysis, microbial load reduction, sensory analysis, peroxide value, and texture analysis. The findings exhibited a direct relationship between plasma power and treatment duration, indicating that an escalation in both parameters induced proportional enhancement in the reduction rate of microbes, with a maximum reduction of over 99% in total plate count, yeast and mould count at 120 W for 20 min and 150 W for 15 min for N₂+O₂ and Ar + O₂ gas combinations, respectively.

However, the moisture content of treated sample decreased, and firmness increased with an increase of power and RF-CP exposure time. This research demonstrates the feasibility of using RF-CP to decontaminate cashews by inactivating microbes, extending shelf life, and altering surface properties, which may enhance texture and appearance. However, it may also induce oxidative changes in lipids and proteins, potentially affecting flavor, nutritional quality, and allergenicity.
