This study investigates the adsorption mechanism and ecological benefits of hydrogen peroxide-modified biochar (HPBC-700) for mitigating tembotrione contamination in soil environments.RESULTSThe oxidative modification introduces abundant oxygen-containing functional groups, including hydroxyl, carboxyl, and carbonyl, which substantially enhance the biochar's adsorption capacity and surface reactivity. Density Functional Theory (DFT) calculations and non-covalent interaction analyses reveal that hydrogen bonding and π-π stacking are the dominant adsorption mechanisms. Among the functional groups, carboxyl contributes the strongest binding due to its ability to form dual hydrogen-bond interactions. In addition to physically immobilizing the herbicide, HPBC-700 improves soil microbial diversity and enriches degradation-related functional taxa, particularly Proteobacteria and Acinetobacter, thereby alleviating pesticide-induced ecological stress.CONCLUSIONThese findings highlight the dual function of HPBC-700 as both an efficient adsorbent and a regulator of soil microbiomes, providing a sustainable strategy for pesticide remediation and agroecosystem restoration.

However, the evolution of resistance in target pests has prompted investigation into the underlying mechanisms. A recent study identified a mutation in the chitin synthase gene (SfCHS2) as a key factor in Vip3Aa resistance in Spodoptera frugiperda. Here, we examined the role of CHS2 in resistance in two additional lepidopteran species: Spodoptera exigua and Agrotis ipsilon.RESULTSUsing a CRISPR/Cas9 gene-editing approach, we generated CHS2 knockout strains in both species. The mutants exhibited high-level resistance to Vip3Aa, surviving the highest tested concentration (800 μg/cm2), with resistance ratios exceeding 33 333-fold in S. exigua and 11 268-fold in A. ipsilon. Additionally, knockout strains lack the peritrophic matrix (PM), whereas the resistant Sfru_R3 strain retained its PM.CONCLUSIONSThese findings further validate the essential role of the CHS2 gene-and the PM it produces-in Vip3Aa toxicity. Complete knockout confers high resistance but imposes severe fitness costs, suggesting that such alleles are unlikely to persist in natural populations.

Migratory pests cause seasonal crop damage through long-distance migration, making it crucial to understand their seasonal activity when estimating outbreak regions. Fall armyworm (FAW), a highly migratory pest, was studied using SDMs to predict its seasonal distribution in the central and eastern USA and explore the environmental factors influencing its distribution.RESULTSWe used monthly environmental and species distribution data to model each month or season individually. Based on model results, the suitable habitat for FAW expands rapidly in summer, covering most of the central and eastern USA in July and August, and then begins to contract in September. Based on the environmental variables included in models for different seasons, FAW distribution in winter is mainly influenced by minimum temperature. In spring, rainfed corn cultivation area and Normalized Difference Vegetation Index (NDVI) also play important roles. In summer, minimum temperature is no longer important, and the main factors are precipitation, evapotranspiration, rainfed corn cultivation area, and NDVI. In autumn, minimum temperature becomes important again, while rainfed corn cultivation area is no longer a key factor.CONCLUSIONThis study indicates that FAW may have outbreaks across the central and eastern USA in July and August, emphasizing the necessity of implementing early large-scale pest control. Using separate models for each season, rather than a single model to predict whether seasonal distribution could improve prediction accuracy by identifying key environmental variables in each season and refining niche characterization. © 2025 The Author(s).

Limited access to preferred resources increases missed opportunity costs (MOCs), which should necessitate uptake of less-preferred alternatives. How animals trade off access to preferred versus less-preferred foods has important implications for wildlife management, especially where anthropogenic, natural, and management-related food sources co-occur. In cropping systems, mouse control relies on their uptake of unpalatable poisons coated on wheat grains, even when high-quality alternatives like sown and spilled grain are available. We tested whether increasing the cost of accessing preferred wheat seeds would shift mice toward consuming a less-preferred food, lentils.RESULTSWe conducted two experiments manipulating the costs of searching for wheat, predicting mice would compensate by eating more lentils. Unexpectedly, mice ate similar quantities of lentils across treatments, regardless of wheat accessibility. We suggest this occurred because lentils contain substantially more protein than wheat, leading to a nutritional MOC associated with wheat - that is, a fitness cost incurred from an imbalanced, wheat-only diet.CONCLUSIONMOCs are rarely defined and are typically framed as time or energy trade-offs, yet animals also incur fitness costs from nutritional imbalance. Bait substrates usually target pest preferences, but uptake may be limited when substrates match the macronutrient composition of background food (e.g., crops). We suggest that bait uptake could be improved by considering nutritional MOCs and selecting substrates that complement the macronutrient composition of background alternatives, thereby exploiting animals' nutritional requirements. © 2025 The Author(s).

Monilinia fructicola, the primary causal agent of brown rot, is especially challenging to manage because of its ability to establish latent infections in fruit, making early detection and control extremely difficult, enabling the disease to spread unnoticed. Therefore, it is essential to develop fast and accurate detection technologies.RESULTSIn this study, a one-pot detection method for M. fructicola, integrating CRISPR-bio-dCas9, recombinase polymerase amplification (RPA), and a lateral flow assay (LFA) was developed. This method could detect the M. fruticola genome in less than 30 min from sample collection to result, with a detection limit of 4 copies/μL of M. fructicola. The RPA/CRISPR-bio-dCas9 LFA method simplified M. fructicola detection by eliminating the need for probes, additional reporters, or specialized equipment, thereby reducing costs and complexity. Furthermore, the streamlined single-tube workflow minimized cross-contamination risks, enabling non-expert workers to perform efficient pathogen screening.CONCLUSIONSThe RPA/CRISPR-bio-dCas9 LFA enabled advanced brown rot management by addressing the limitations of traditional detection (slow speed, high cost, complexity). With high sensitivity and a short detection time using an equipment-free design, it enabled practical on-site detection of M. fructicola, allowing timely interventions to reduce pre- and post-harvest losses in fruit production. © 2025 Society of Chemical Industry.","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":"71 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145071824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A dual binding strategy was adopted to prepare TMX core-shell controlled-release granules (TMX-GR). By adjusting parameters such as iron(III) concentration, glycine (Gly) concentration, material ratio, and particle size, products with distinct release properties were successfully fabricated.
