The growing demand for sustainable pest control necessitates advanced delivery systems that enhance insecticidal efficacy while minimizing environmental impact. In this study, we developed and evaluated polycaprolactone (PCL)-based nanoparticles for encapsulating lufenuron, an insect growth regulator, with the primary aim of developing and characterizing the nanoformulation and the secondary aim of assessing its potential efficacy against Rachiplusia nu relative to conventional formulations. The nanoparticles were synthesized via nanoprecipitation and characterized by particle size (264 ± 5 nm), zeta potential (–44 ± 1.2 mV), encapsulation efficiency (>99 %), and surface morphology, with atomic force microscopy confirming uniform spherical structures. Stability studies over 90 days showed negligible size and surface charge variation, ensuring formulation robustness under storage conditions. In vitro release assays revealed an erosion-controlled release profile, with the nanoencapsulated formulation releasing the active compound up to eight times more slowly than free lufenuron. Biological performance was validated through in vitro (artificial diet) and in vivo (semi-field) assays conducted in duplicate trials. The nanoformulated (NP_PCL_LFN) and commercial lufenuron (LFN) achieved nearly 100 % larval mortality at the highest tested concentrations. NP_PCL_LFN maintained effective control at a reduced application rate, showing equivalence to the commercial formulation under low-concentration conditions. In semi-field trials, both treatments provided > 76 % control at full dose, with nanoencapsulation sustaining comparable efficacy at lower levels. These results underscore the potential of PCL-based nanoformulations to enhance pesticide stability, control release kinetics, and reduce application rates, offering a promising route for precision agriculture and resistance management in integrated pest control strategies.

对可持续虫害控制日益增长的需求需要先进的输送系统，以提高杀虫效果，同时最大限度地减少对环境的影响。在这项研究中，我们开发并评估了聚己内酯（PCL）纳米颗粒包封昆虫生长调节剂氟虫腈，主要目的是开发和表征纳米配方，次要目的是评估其相对于常规配方对牛棘虫的潜在功效。采用纳米沉淀法合成了纳米颗粒，并对其粒径（264 ± 5 nm）、zeta电位（-44 ± 1.2 mV）、包封效率（>99 %）和表面形貌进行了表征，原子力显微镜证实了纳米颗粒的均匀球形结构。90天的稳定性研究表明，尺寸和表面电荷变化可以忽略不计，确保了配方在储存条件下的稳健性。体外释放试验揭示了一个侵蚀控制的释放曲线，纳米胶囊制剂释放活性化合物的速度比游离的氟虫腈慢8倍。通过重复试验进行的体外（人工饲料）和体内（半场）试验验证了生物性能。在最高浓度下，纳米配方（NP_PCL_LFN）和商用氟虫腈（LFN）的幼虫死亡率接近100% %。NP_PCL_LFN在减少施用量的情况下仍能保持有效的控制，在低浓度条件下与商业配方相当。在半现场试验中，两种治疗方法在全剂量下提供了>； 76 %的控制，纳米胶囊化在较低剂量下保持相当的疗效。这些结果强调了基于pcl的纳米配方在提高农药稳定性、控制释放动力学和降低施用量方面的潜力，为精准农业和害虫综合防治策略中的抗性管理提供了一条有希望的途径。

CeO₂ nanoparticles commercially utilised in petroleum, pharma and agriculture industry. Their release and deposition in agri-environment may affect the plant growth yield. Their accumulation in plant poses threat to consumers and human as well. In this study, the effect of CeO₂ NPs (0; 2; 4 µg mL⁻¹) on plant stress markers, antioxidant defence system, bio-macromolecule composition and bacoside-A of Bacopa monnieri has been studied. ICP-MS and SEM EDAX data confirmed the uptake and buildup of cerium in different tissues of B. monnieri. Ce accumulation in stomata caused structural distortion in stomatal morphology. The concentration dependent accumulation of cerium accompanied upregulation of oxidative stress markers (MDA, H₂O₂)_. The alterations in bio-macromolecules also depended on exposure concentrations of CeO₂ NPs. Further, increased levels of cellular and enzymatic antioxidants have been observed at both experimental concentrations of CeO₂ NPs as compared to control. The stimulated antioxidants served as a plant defence response against CeO₂ NPs induced abiotic stress. A maximum increment of 53.3 % in Bacoside-A yield has also been observed at 4 µg mL⁻¹ CeO₂ NPs. The ability B. monnieri to internalize CeO₂ NPs may serve as a candidate species for phytoremediation of CeO₂ NPs contaminated agri-environments. Further CeO₂ NPs, elevated phytotoxic risk raises concerns about their regulated use and disposal in agri-environment.

CeO2纳米颗粒在石油、制药和农业工业中的商业应用。它们在农业环境中的释放和沉积会影响植物的生长产量。它们在植物体内的积累对消费者和人类都构成了威胁。本研究研究了CeO2 NPs（0; 2; 4 µg mL−1）对假马尾草植物胁迫标记物、抗氧化防御系统、生物大分子组成和假马尾草苷a的影响。ICP-MS和SEM EDAX数据证实了白僵菌在不同组织中对铈的吸收和积累。Ce在气孔中的积累导致气孔形态结构扭曲。铈的浓度依赖性积累伴随着氧化应激标志物（MDA, H2O2）的上调。生物大分子的变化也依赖于暴露浓度的CeO2 NPs。此外，与对照组相比，在两种实验浓度的CeO2 NPs下，细胞和酶抗氧化剂水平均有所增加。受刺激的抗氧化剂是植物对CeO2 NPs诱导的非生物胁迫的防御反应。当浓度为4 µg mL−1 CeO2 NPs时，Bacoside-A的产率最高可达53.3 %。monnieri内化CeO2 NPs的能力可以作为植物修复CeO2 NPs污染农业环境的候选物种。此外，CeO2 NPs的植物毒性风险升高引起了人们对其在农业环境中的规范使用和处置的关注。

Soil salinity severely restricts the growth of Lallemantia iberica, a salt-sensitive medicinal plant. This study evaluated whether chitosan nanoparticles (CNs) enhance salinity tolerance by modulating physiological and biochemical responses. Plants subjected to 0, 30, and 60 mM NaCl were sprayed with 0, 75 mg L⁻¹ (CN75) or 150 mg L⁻¹ (CN150). Severe salinity reduced biomass and chlorophylls by ∼40–65 %, caused a sevenfold decline in carotenoids, doubled malondialdehyde (MDA), increased hydrogen peroxide (H₂O₂) by ∼65 %, and lowered the K⁺/Na⁺ ratio from 8.49 to 0.72. CNs alleviated these impairments in a dose- and stress-dependent manner: CN75 was most effective under severe stress, reducing MDA by 36 %, lowering H₂O₂ to ∼65 % of untreated plants, and increasing total soluble protein by ∼25 %, while CN150 supported higher pigment retention and partially restored ionic homeostasis under moderate salinity. The CN application also enhanced antioxidant enzyme activities (SOD, CAT, POD), stabilised proteins, and stimulated phenolic metabolism by increasing phenylalanine ammonia-lyase (PAL) and tyrosine ammonia-lyase (TAL) activities, consistent with elevated levels of gallic and rosmarinic acids detected by HPLC. Multivariate analyses confirmed coordinated improvements in redox balance, osmotic regulation, ion homeostasis, and secondary metabolism. By strengthening antioxidant capacity and metabolic integration, CNs enabled L. iberica to maintain functional stability and growth under salinity stress. Totally, these findings highlight CNs as effective nanobiostimulants that enhance resilience through integrated physiological and metabolic adjustments.

土壤盐度严重限制了一种对盐敏感的药用植物伊比利亚的生长。本研究评估了壳聚糖纳米颗粒（CNs）是否通过调节生理生化反应来增强耐盐性。分别用0.75 mg L−1 （CN75）和150 mg L−1 （CN150）分别喷洒0、30和60 mM NaCl的植株。严重的盐度使生物量和叶绿素减少了~ 40-65 %，类胡萝卜素下降了7倍，丙二醛（MDA）增加了一倍，过氧化氢（H2O2）增加了~ 65 %，K+/Na+比值从8.49降低到0.72。CNs以剂量和胁迫依赖的方式减轻了这些损伤：CN75在严重胁迫下最有效，使未处理植物的MDA降低了36% %，H2O2降低到~ 65 %，总可溶性蛋白增加了~ 25 %，而CN150在中等盐度下支持更高的色素保留和部分恢复离子稳态。CN还增强了抗氧化酶（SOD、CAT、POD）活性，稳定了蛋白质，并通过增加苯丙氨酸解氨酶（PAL）和酪氨酸解氨酶（TAL）活性来刺激酚代谢，这与HPLC检测到的没食子酸和迷迭香酸水平升高一致。多变量分析证实了氧化还原平衡、渗透调节、离子稳态和次级代谢的协调改善。CNs通过增强抗氧化能力和代谢整合，使伊比利亚菌在盐度胁迫下保持功能稳定和生长。总之，这些发现强调了中枢神经网络作为有效的纳米生物兴奋剂，通过综合生理和代谢调节来增强恢复力。

Drought stress is a major constraint on global potato productivity, necessitating innovative mitigation strategies. This study investigates the potential of exogenous serotonin (5HT) and selenium nanoparticles (SeNPs), both individually and in combination, as biostimulants to enhance drought resistance in potato. Through integrated physiological, biochemical and molecular analyses, we demonstrate that while individual treatments provide moderate protection, the combined 5HT-SeNPs application significantly enhances water relations, photosynthetic efficiency and water use efficiency under drought conditions. The synergistic treatment achieved superior water retention, optimal osmotic adjustment and enhanced photosynthetic recovery compared to individual applications. Furthermore, 5HT and SeNPs synergistically strengthened antioxidant defenses by reducing H₂O₂ accumulation to control levels while maximizing enzymatic activities (SOD, CAT, POD) and promoting balanced osmolyte accumulation. Phytohormone profiling revealed that the combined treatment effectively modulates stress signaling by maintaining optimal ABA and IAA balance while enhancing SA and JA-mediated defense responses. Transcriptomic analysis identified extensive gene expression changes, indicating comprehensive metabolic reprogramming in photosynthesis, hormone signaling, phenylpropanoid biosynthesis and antioxidant pathways. Our findings provide novel insights into the synergistic mechanisms of 5HT and SeNPs-mediated drought tolerance and highlight their potential as an innovative, sustainable strategy to improve potato resilience in water-limited environments.

干旱胁迫是全球马铃薯生产力的主要制约因素，因此需要创新的缓解战略。本研究探讨了外源性5 -羟色胺（5HT）和硒纳米颗粒（SeNPs）单独或联合作为生物刺激剂增强马铃薯抗旱性的潜力。通过综合的生理、生化和分子分析，我们发现在干旱条件下，单个处理提供适度的保护，但5HT-SeNPs联合施用显著提高了水分关系、光合效率和水分利用效率。与单独施用相比，协同处理获得了更好的保水性，最佳的渗透调节和增强的光合恢复。此外，5HT和SeNPs通过减少H₂O₂积累来控制水平，同时最大化酶活性（SOD， CAT， POD）和促进平衡的渗透物积累，从而协同增强抗氧化防御。植物激素分析显示，联合处理通过维持最佳的ABA和IAA平衡，同时增强SA和ja介导的防御反应，有效调节胁迫信号。转录组学分析发现了广泛的基因表达变化，表明在光合作用、激素信号、苯丙类生物合成和抗氧化途径中进行了全面的代谢重编程。我们的研究结果为5HT和senps介导的抗旱性的协同机制提供了新的见解，并强调了它们作为一种创新的、可持续的策略来提高马铃薯在缺水环境中的抗旱性的潜力。
