In this study, we investigated the stimulation of the plant immune system as a strategy to reduce weed growth, a mechanism not exploited by any commercial herbicide. Plants possess an innate immune system able to detect pathogens' molecules such as cerato-platanin (CP), a fungal protein elicitor produced by Ceratocystis platani. As sensitivity of arable weeds to microbial elicitors is mostly unknown, the ability of CP to reduce germination and early seedling growth was examined in some Poaceae and Amaranthaceae by using wheat as an off-target species.RESULTSCP-treated seeds from Lolium multiflorum, Digitaria sanguinalis and Amaranthus hybridus resulted in stunted seedling growth, demonstrating sensitivity to the protein. In contrast, A. palmeri, A. tuberculatus and Avena fatua were unaffected by the treatment. A more detailed characterization of the sensitivity of L. multiflorum showed that CP-specific growth inhibition occurred at concentrations ≥75 μM. Western-blot analysis showed absorption of CP by L. multiflorum seedlings, while RT-qPCR analyses revealed the overexpression of defense genes, such as the pathogenesis-related (PR) gene chitinase 1 and the ethylene-biosynthesis gene ACO1. CP was also effective on Lolium spp. populations resistant to the acetyl-coenzyme A carboxylase (ACCase) inhibitor pinoxaden, while it did not adversely affect germination of Triticum aestivum.CONCLUSIONBesides the classic use as resistance inducers against pests and diseases, we show that plant immune defense activators from microbes may act as selective herbicides with a mode of action so far unexploited. © 2025 The Author(s).

However, the genomic basis and evolutionary history of homoterpene biosynthesis in legumes remain largely unexplored, limiting our understanding of their functional diversification and ecological roles.RESULTSUsing a yeast expression system, we identified two novel, tandemly duplicated cytochrome P450 genes, PlCYP82D47-like and PlCYP82D47, involved in DMNT and TMTT biosynthesis in lima bean (Phaseolus lunatus). PlCYP82D47-like catalyzes the conversion of (E)-nerolidol and (E,E)-geranyllinalool to DMNT and TMTT, respectively, while PlCYP82D47 specifically converts (E)-nerolidol to DMNT. Evolutionary analysis revealed syntenic tandem duplicates of these genes in lima bean, cotton, and Arabidopsis, suggesting a conserved genomic architecture for DMNT/TMTT biosynthesis among dicotyledonous plants and implying potential gene loss events in this genomic region. Computational modeling identified residues L324 and L505 as critical for substrate recognition by PlCYP82D47. Site-directed mutagenesis and in vitro enzymatic assays confirmed that substitutions at these residues significantly reduced catalytic activity.CONCLUSIONOur findings provide new insights into the enzymatic and evolutionary basis of homoterpene biosynthesis in legumes and offer promising targets for future metabolic engineering applications. © 2025 Society of Chemical Industry.","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":"16 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370379","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}

Understanding the mechanisms underlying its rapid host adaptation is critical for developing sustainable integrated pest management (IPM) strategies.METHODSWe used age-stage, two-sex life table analyses coupled with untargeted metabolomics to systematically evaluate the effects of host shifts among three key host plants-luffa (Cucurbitaceae; Luffa acutangula), mango (Anacardiaceae; Mangifera indica), and bitter gourd (Cucurbitaceae; Momordica charantia)-on the developmental fitness and metabolic shifts of Z. tau.RESULTSZeugodacus tau exhibited a distinct intrinsic rate of increase (r), with L. acutangula being the most favored host (r = 0.0914 ± 0.0038), followed by Momordica charantia (0.0785 ± 0.0011) and Mangifera indica (0.0685 ± 0.0038). Remarkably, host-shifted populations achieved demographic stability within two generations, accompanied by rapid recovery of fecundity and host-specific metabolic adjustments, particularly in energy-related pathways (e.g., amino acid metabolic pathways).CONCLUSIONThis study identifies Z. tau as an invasive pest with exceptional adaptive capacity driven by metabolic plasticity.

Accurate estimation of its aboveground biomass (AGB) is therefore essential for effective carbon management. However, the influence of its primary leaf-feeding pest, Pantana phyllostachysae Chao (P. phyllostachysae), on AGB remains poorly understood, potentially compromising estimation accuracy. This study aims to develop allometric equations and integrate them with machine learning algorithms to accurately estimate the AGB of Moso bamboo forests under varying levels of pest stress.RESULTSAllometric equations exhibited strong estimation performance across all pest infestation levels, with R2 values exceeding 0.93, root mean square error (RMSE) values below 0.66 kg, and mean absolute error (MAE) values under 0.51 kg. Among the machine learning approaches evaluated, the Extreme Gradient Boosting (XGBoost) algorithm demonstrated superior performance, yielding an R2 of 0.8593, RMSE of 0.5176 kg, and MAE of 0.4313 kg. A clear negative correlation was identified between the severity of P. phyllostachysae infestation and AGB, with biomass values decreasing progressively from healthy to severely infested stands.CONCLUSIONIncorporating pest factors into AGB estimation models significantly enhances model accuracy and captures the nuanced effects of pest stress on biomass accumulation. This integration improves model generalizability and ecological relevance, offering valuable insights for sustainable forest management and carbon accounting. The findings highlight the importance of explicitly considering pest dynamics in biomass modeling and carbon management strategies, laying a robust foundation for future research on pest-biomass interactions in forest ecosystems. © 2025 Society of Chemical Industry.","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":"13 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370371","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}

The withdrawal of synthetic chemical molluscicides due to human health and environmental concerns has prompted research into other control methods. Particular attention has focussed on behaviour‐modifying chemicals (semiochemicals), most of which are derived from plants and other natural sources and include attractants, repellents and deterrents. This review provides a comprehensive overview of the use of semiochemicals in managing D. reticulatum and discusses their potential for use in integrated pest management (IPM) programmes. We reviewed trends in research publications on semiochemicals in relation to synthetic molluscicides and biological control methods. Besides the identification of promising plant‐based candidate semiochemicals, plants with attractant properties were identified for use as trap crops. These could be used with the main crop treated with repellents in ‘push–pull’ IPM programmes. Extracts from plants as well as predators and entomopathogenic fungi have shown promise against grey field slugs by inducing avoidance, antifeeding behaviour or even mortality, thereby reducing crop damage. Elucidation of the structure and mode of action of specific chemical compounds responsible for slug attraction or repulsion could lead to the development of new products for management of the grey field slug. © 2025 The Author(s).

Merr.] and cotton (Gossypium hirsutum L.) The spectral response of plant injury at the field scale is a crucial knowledge gap that may help researchers understand dicamba's fate in the environment. Non‐DT soybean is the ideal sentinel crop owing to its extreme sensitivity. Field experiments were conducted to characterize the reflectance spectra associated with dicamba vapor drift injured soybean canopies. The objective was, under field conditions and using land‐based remote sensing, to determine what regions of the EM correlate to dicamba‐injured soybean canopies.RESULTSSoybean injury was observed 8 days after treatment at only 1/10000th of a labeled use rate of dicamba. Correlations between simulated vapor drift and reflectance spectra at the single channel red‐edge and vegetative indices excess red (ExR) and green leaf index (GLI) were observed. The study demonstrates the potential for detecting off‐target dicamba vapor drift injury in soybean, with reflectance spectra following dicamba treatments observed at all spectral channels.CONCLUSIONSDifferentiating dicamba‐injured from dicamba‐tolerant soybean canopies can be achieved using single spectral channels and vegetative indices. These findings usher in the possibility that remote sensing satellites, which are well‐documented for identifying crop stress on the landscape, could be harnessed to understand the extent to which dicamba injury appears following over‐the‐top (OTT) application in DT soybean. Remote sensing technology could be instrumental in monitoring off‐target herbicide injury and mitigating the effects of dicamba drift. © 2025 The Author(s).

Alanine scanning identified an arginine and lysine rich patch on the peptide's surface that is critical for bioactivity. Targeted stability studies on these basic residues identified a single site, R9, to be the rate limiting site in U1‐AGTX‐Ta1b proteolysis. Mutation of position R9 to glutamine was sufficient to stabilize the peptide and render the toxin orally active with the additional benefit of enhanced temperature stability. Further refinement of the peptide to remove an O‐linked glycosylation site and prevent exoprotease activity during expression in yeast led to a final peptide sequence suitable for commercialization as a bioinsecticide. This peptide displayed activity comparable to commercial insecticides in a range of crop/pest combinations.CONCLUSIONA novel, peptide‐based bioinsecticide derived from spider venom was developed to be stable and active by ingestion by lepidopteran pests.

Although they demonstrate extraordinary herbicidal activity against broadleaf weeds, their efficacy against grass weeds remains limited. To develop broad-spectrum herbicide candidates, a series of 3-(pyridin-2-yl)benzothiazol-2-one derivatives bearing acylalanine moiety were designed in this study.RESULTSUsing a hybridization-substructure-combination strategy, the active groups of acylalanine fungicides were incorporated into the 3-(pyridin-2-yl)benzothiazol-2-one scaffold. Starting from benzothiazol-2-one, 20 title compounds were synthesized via aromatic nucleophilic substitution, nitration, reduction, N-alkylation and acylation successively. The herbicidal activities of these compounds against Echinochloa crus-galli and Portulaca oleracea were preliminarily evaluated by Petri dish assays. Additionally, the post-emergence herbicidal activity of the most potent compounds, I-09 and I-13, was further assessed against multiple weed species in greenhouse pot experiments. Compound I-09 demonstrated 100% post-emergence herbicidal efficacy against broadleaf weeds (Solanum nigrum; Capsella bursa-pastoris; Descurainia sophia; Veronica polita) at an application rate of 75 g a.i./ha. Structure-activity relationship (SAR) analysis revealed that the herbicidal activity was determined by the synergistic effects of substituents on the pyridine ring and side chains attached to the aniline moiety. The 3-fluoro-5-trifluoromethyl-pyridine group was identified as the optimal substitution pattern at the 3-position of benzothiazol-2-one, and the simultaneous introduction of ethyl acetyl and propionyl groups was found to be essential for maintaining activity.CONCLUSIONA new class of acylalanine-containing 3-(pyridin-2-yl)benzothiazol-2-one derivatives was discovered as promising candidates for herbicides.
