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. Transgenerational plastic responses may help in understanding how species and ecosystems adapt to environmental temperature changes.

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}

However, achieving accurate detection through object detection methods remains challenging due to small target scales, subtle inter-species morphological differences, and complex background interference. Therefore, this study proposes a high-precision SGIP model based on Transformer architecture called Multi-Species Stored-Grain Insect Pest DEtection TRansformer (MSGP-DETR). To enhance small target detection capabilities, the network incorporates a Discrete Cosine Transform Small Target Enhancement Module (DSTEM) for frequency-domain feature enhancement. Additionally, a Multi-Point Spiral Mamba (MPSM) module is designed to capture long-range dependencies through linear computational complexity. Moreover, an Adaptive Partial Enhancement Lightweight Aggregation Network (APELAN) is developed to reduce computational complexity while preserving essential feature information. To evaluate MSGP-DETR's performance in SGIP detection, we collected adult live samples of eight common SGIP species and constructed a dataset named SGIP8. Experimental results demonstrate that MSGP-DETR achieves 94.6 % AP₅₀ and 50.1 % AP_50:95 on the SGIP8 dataset, with only 9.2M parameters and 19.7 GFLOPs computational complexity. The detection speed reaches 36.6 FPS, with overall performance surpassing current mainstream models.

This closed metabolic architecture imposes severe constraints on physiological trade-offs, particularly under environmental stress. Cold exposure represents a realistic ecological stressor frequently encountered by stored-product pests and field populations during transport or overwintering, influencing both survival and population dynamics. Here, we demonstrate that cold functions not only as a sublethal stressor but also as a potential natural regulator of pest fitness in the seed beetle <em>Callosobruchus maculatus</em> (Coleoptera: Bruchidae), uncovering sex-specific energy allocation strategies and intergenerational vulnerabilities. Through four integrated experiments, we exposed adults and early developmental stages to freezing temperatures (−20 °C) and chilling temperatures (4 °C), quantifying mortality thresholds, adjusted post-stress lifespan, fecundity, hatch success, adult emergence, and sex ratios. Cold-stressed females preserved somatic longevity by reducing reproductive investment—a pattern consistent with adaptive energy prioritization. In contrast, males suffered progressive post-stress declines in survival with increasing cold duration. These results reveal how aphagy amplifies the energetic cost of stress, leading to asymmetric resilience between sexes and across generations, with direct implications for pest persistence and control under fluctuating temperature regimes.
