Traditional storage methods often lead to microbial spoilage, nutrient loss, and reduced market value. This study evaluated the effectiveness of five hermetic storage bags Purdue Improved Crop Storage (PICS™), GrainPro™, Savegrain®, Ecotact®, and Pro-harvest® compared with a jute bag control, in preserving artificially infested turmeric rhizomes over 11 months under ambient conditions (26–32 °C, 55–75 % RH) at the Central Institute of Post-Harvest Engineering and Technology (CIPHET), Ludhiana, Punjab, India. Each bag type was tested with three replicate bags and each bag contained rhizomes infested with 10 pairs of adult cigarette beetles <em>(Lasioderma serricorne</em>). Physicochemical parameters, including fiber, oleoresin, and ash, were measured, and color changes (ΔE, h_ab, C∗) were calculated. Microbiological analyses included total plate count, yeast and mold enumeration, and screening for coliforms, <em>E. coli</em>, and Salmonella spp. Hermetic bags, especially PICS and Pro-harvest, retained 15–18 % more oleoresin and 10–12 % more fiber than jute bags. Total plate counts in jute bags reached 18.93 × 10⁶ CFU/g, significantly higher than hermetic treatments (3.53–6.5 × 10⁶ CFU/g). No coliforms, <em>E. coli</em>, or <em>Salmonella</em> were detected in hermetic bags. Scanning Electron Microscopy (SEM) analysis showed the presence of holes caused by insect activity in rhizomes stored in jute bags. These findings suggest that hermetic bags, especially PICS and Pro-harvest, offer a chemical-free, efficient method for long-term turmeric storage.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"116 ","pages":"Article 102976"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188123","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}

Three parameters viz. adult emergence, number of damaged grains, and grain weight loss were recorded at 30, 60, and 90 days after infestation, with all showing a consistent linear increase over time. Ten BILs exhibited high levels of resistance, with PN410, PN372, and PN266 showing strong and stable performance across all recorded parameters.

Inclusive composite interval mapping (ICIM) detected four QTLs on chromosomes 4D, 7A, and 7D. Notably, <em>QDg.pau-4D/QGwl.pau-4D</em> on chromosome 4D showed a pleiotropic effect, contributing to both number of damaged grains and grain weight loss. Furthermore, <em>QAe.pau-7A</em> and <em>QGwl.pau-7D</em> were identified as high-confidence loci associated with resistance.

This poses significant stress on ectotherms, whose bodily function depends on ambient temperatures. The ability of species to adapt within and/or across generations through phenotypic plasticity is thus a critical ecological topic. We investigated transgenerational thermal plasticity of the larger grain borer, <em>Prostephanus truncatus</em>, a devastating postharvest maize pest. Specifically, we tested the effects of parental exposure to sublethal heat stress (35 and 38 °C for 2 h; 80 % RH) on progeny thermal— and ecological—performance. Following acclimation, the colonies were separately maintained on shelled maize at optimum conditions of 32 °C at 65 ± 10 % RH. After 21 d, adult beetles were removed and the emerging progeny respectively labelled as F₁ treatments (F₁_35 °C and F₁_38 °C). Subcultures from these 2 × F₁ treatments were sampled in the same manner to obtain F₂ (F₂_35 °C and F₂_38 °C) and subsequently F₃ (F₃_35 °C and F₃_38 °C) generations which were then evaluated against parental (control) cultures maintained at optimal conditions 32 °C (P_32 °C). Our results showed that parental heat acclimation: (i) had transgenerational physiological— but not ecological-progeny fitness advantage; (ii) decreased critical thermal limit ranges; (iii) had cross-protection improvement in cold tolerance; and (iv) had transgenerational physiological responses that may last generations.

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 <em>S. zeamais</em> to three isolated high-purity essential oil-derived compounds – 1,8-cineole, (S)-(−)-Limonene, and Eugenol – using a four-arm olfactometer. Adult <em>S. zeamais</em> 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.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"116 ","pages":"Article 102898"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145584338","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}
