We present a validated, algorithmic alternative, the CPG $$ boldsymbol{CPG} $$ model, that integrates climatic suitability ( C $$ boldsymbol{C} $$ ), weed-related publication frequency (P) and global occurrence data ( G $$ boldsymbol{G} $$ ), using publicly available databases and artificial intelligence (AI)-assisted text screening with a large language model (LLM).RESULTSThe CPG $$ CPG $$ model was tested against independent weed hazard classifications for New Zealand and California. In New Zealand, 89% of 480 randomly selected plant taxa had sufficient data to generate scores, which aligned well with expert classifications and moderately with outputs from the 48-question WRA [Pheloung PC, Williams PA, and Halloy SR. Journal of Environmental Management 57:239-251 (1999)]. For more than 5000 species assessed using Randall's 14-criteria generalised risk mode [Randall RP, 20th Australasian Weeds Conference: 5-12 (2016)], all CPG $$ CPG $$ variables were informative. The model also showed strong agreement with the 19-criteria California weed hazard system. Multinomial regression and receiver operator characteristic curve (ROC) analyses confirmed consistent predictive performance, with true-positive rates from 0.69 to 0.90 and true-negative rates from 0.71 to 0.97. It effectively distinguished high- from low-hazard species. Sensitivity analysis showed that as evidence for weediness increased, score stability improved, supporting robust rankings for high-hazard species.CONCLUSIONThe CPG $$ boldsymbol{CPG} $$ model offers a transparent, scalable and cost-effective tool for early-stage weed hazard screening. It delivers substantial time savings over attribute-based WRAs while maintaining alignment with expert evaluations. The model enables rapid triage of large species lists, including actual or potentially introduced taxa under current and future climates, supporting prioritisation for detailed risk or management feasibility assessments. Its automation and reproducibility make it a valuable tool for global biosecurity and invasive species management. © 2025 The Author(s).

Biocontrol is an environmentally friendly and promising approach for clubroot management. Endophytic bacteria are known for their ability to promote plant growth and induce resistance against plant diseases. In the Plasmodiophora brassicae-Brassica pathosystem, microbial communities are poorly understood, and their biocontrol potential for clubroot remains unexplored.RESULTSIn this study, we investigated the endophytic bacterial communities in root samples with different levels of clubroot infection. Subsequently, we employed sequencing analysis and culture-dependent isolation to profile these communities. Our results indicated differences in bacterial composition between D (galled) and H (asymptomatic) roots. Notably the enrichment of Pseudomonas species in H. Culture-dependent bacterial isolation suggested that three Pseudomonas strains (H10, H13, and H15) from H had biocontrol potential, which was confirmed by their effects of 49% reductions in resting spore germination, along with abilities in environmental pH adjustment and biofilm formation. Specifically, during clubroot development, Pseudomonas brassicacearum strain H13 reduced clubroot severity by 51%, suppressed Plasmodiophora brassicae biomass by over 12% in roots and 37% in soil, effectively colonized roots, and increased soil pH. Strain H13 also influenced the expression of plant hormone-related genes, including a 3.4-fold up-regulation of NPR1 at 7 days post-inoculation (dpi), and down-regulation of CKX, AO1, and DWF4 by 84%, 88%, and 40%, respectively, at 21 dpi.CONCLUSIONSThese findings suggest that endophytic Pseudomonas strains, particularly strain H13, hold promise as effective biocontrol agents by reducing chemical fungicide application for sustainable clubroot management. © 2025 Society of Chemical Industry.","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":"28 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007098","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}

However, host defenses have limited the effectiveness of these fungi in practice. Utilizing genetic engineering-based technology could be a promising strategy to enhance the killing efficiency of these fungi against insect pests.RESULTSIn this study, we identified a gene Lysyloxidase (SfLox) in Sogatella furcifera, with a Scavenger receptor Cys-rich domain that significantly responds to infection by the fungus Metarhizhium anisopliae. RNA interference (RNAi) targeting this gene reduced the survival of the host S. furcifera when infected with M. anisopliae. Additionally, introducing double-stranded RNA (dsRNA) targeting SfLox into M. anisopliae, resulting in the genetically engineered strain M. anisopliae-Sfox-RNAi, eventually enhanced its virulence against the rice pest S. furcifera. Further research demonstrated that genetically engineered M. anisopliae promoted the formation of hyphal bodies in the host's body compared to the wild strain, while also disrupting the host's immune responses.CONCLUSIONSExpressing host Lysyloxidase dsRNA in M. anisopliae improved its virulence against insect hosts and facilitated its proliferation within the host's body. This study proposes that the combination of dsRNA with entomopathogenic fungi through genetic engineering could serve as an effective approach for controlling insect pests.

In this study, we aimed to investigate the epidemiology of Monilinia spp. on almonds in two orchards in the Ebro Valley, with a focus on (i) primary inoculum sources through sampling of affected mummified fruiting structures from trees and the ground before blooming; (ii) secondary inoculum sources postblooming; and (iii) disease dynamics throughout the season in relation to meteorological data.RESULTSMonilinia laxa was the primary species affecting almonds in the Ebro Valley. Furthermore, early-stage mummified fruiting structures frequently adhered to branches (3.8 log conidia/mummified fruiting structure), whereas late-stage mummified fruiting structures were predominantly found on the ground. Additionally, cankers present before blooming (6.0 × 102 and 1.4 × 103 conidia/canker) served as primary inoculum sources. Inoculum incidence and concentration were significantly higher in late-stage fruits (50-100%, 8.5 × 103-2.5 × 105 conidia/plant organ) than those in flowers (20-30%, 2.0-4.0 × 103 conidia/plant organ) or those in postblooming cankers (1.0 × 102-1.8 × 103 conidia/canker). Infection dynamics of blossom blight in both orchards peaked during the last third of April under favorable meteorological conditions, specifically within the 10 days preceding the assessments. Significant correlations were found between infections progression and meteorological parameters, including temperature, relative humidity, rainfall and leaf wetness.CONCLUSIONThese findings provide critical insights into sustainable disease management practices and the optimal timing of protective measures against blossom blight. © 2025 The Author(s).

This study aimed to clarify the adaptation of three A. gossypii haplotypes (Hap1, Hap3, Hap4) to four legume hosts: cowpea (Vigna unguiculata) varieties Zhongshouluchangfeng (ZLC) and Zhongshoucuichangfeng (ZCC), hyacinth bean (Lablab purpureus) and winged bean (Psophocarpus tetragonolobus).RESULTSResults showed Hap1 and Hap4 on cowpeas had higher net reproductive rate (R0 > 25) and intrinsic rate of increase (r > 0.36) than on hyacinth bean and winged bean (R0 < 6, r < 0.27). Meanwhile, Hap3 exhibited poor life-table parameters on all legumes. Among legumes, all haplotypes preferred hyacinth bean and refused to feed on winged bean. EPG analysis showed that Hap1 and Hap4 had longer nonprobing time on winged bean, and prolonged xylem ingestion on hyacinth bean. All haplotypes fed longer on cowpea phloem than on hyacinth bean and winged bean. Notably, the proportion of saliva secretion time in the phloem feeding duration of A. gossypii feeding on winged bean exceeded 75%. A. gossypii that fed on cowpeas secreted the highest amount of honeydew CONCLUSION: Different haplotypes of cotton aphids show differentiated adaptability to legumes, and there also is differentiation in the aphid resistance among legumes.

However, the mechanisms governing their uptake and detoxification in wheat remain unknown. This study aimed to determine how macronutrients and endogenous signaling compounds regulate PTC absorption and metabolism in wheat seedlings.RESULTSHigh potassium availability markedly enhanced PTC uptake, resulting in a > 600% increase in PTC uptake over 12 h compared to the low potassium. Exogenous application of indole-3-acetic acid and brassinolide led to significant increases in PTC accumulation by 121.7% and 94.4%, respectively. Transcriptomic analysis revealed that PTC activated detoxification pathways, with prominent up-regulation of adenosine triphosphate (ATP)-binding cassette transporters and mitogen-activated protein kinase (MAPK) signaling components. Under nitrogen-deficient conditions, 1493 genes were specifically down-regulated, including those related to ribosome biogenesis, phenylalanine metabolism, and membrane transport, indicating a reduced detoxification capacity and enhanced dPTC retention.CONCLUSIONNitrogen availability plays a pivotal role in modulating the molecular response of wheat to PTC exposure. Nitrogen deficiency markedly down-regulated key genes involved in detoxification processes, thereby aggravating PTC-induced phytotoxicity.

While a target-site mutation at EPSPS2 (P106S) was recently identified, it failed to account for many resistant cases. These findings underscore the need to re-evaluate the genetic basis of glyphosate resistance in this species.RESULTSUsing an F2 population derived from glyphosate-resistant and susceptible biotypes, we disentangled the individual and combined effects of target-site resistance (TSR) and NTSR. Dose-response phenotyping and genotyping revealed that NTSR conferred broad protection across a wide range of glyphosate doses, while TSR provided a more limited, dose-dependent benefit. When both mechanisms were present, median lethal dose (LD50) values greatly exceeded additive expectations, indicating a synergistic interaction. Quantitative trait locus (QTL) mapping identified a major-effect locus associated with NTSR on chromosome 4, with candidate genes linked to membrane transport and subcellular compartmentalization processes. Segregation distortion and recombination frequency estimates suggest moderate genetic linkage between TSR and NTSR loci, facilitating co-inheritance of resistance alleles.CONCLUSIONThis study provides the first explicit quantitative analysis of gene × gene interactions underlying herbicide resistance in C. canadensis. By disentangling TSR and NTSR, we show that single copies of the TSR and NTSR alleles confer approximately nine-fold and seven-fold glyphosate resistance, respectively. When combined, these mechanisms exhibit synergism, resulting in resistance levels that exceed additive LD50 expectations by more than two-fold. Both TSR and NTSR loci have been mapped to chromosome 4, and moderate genomic linkage (~27% recombination) between them will likely contribute to the persistence and spread of high-level resistance, even under low selection pressure. © 2025 His Majesty the King in Right of Canada.

In moths, light traps typically capture more mated females than unmated ones; however, the mechanisms driving this discrepancy remain unclear.RESULTSIn this study, we examined how mating status influences female light capture in the diamondback moth (DBM; Plutella xylostella). Both field and laboratory experiments consistently showed that mated females had higher light capture rates, especially during the first 2 h of the scotophase. Behavioral assays indicated that mating increased locomotor activity, including total movement distance and speed. Transcriptomic analyses of female heads revealed significant upregulation of juvenile hormone (JH)-inducible genes-particularly juvenile hormone esterase (JHE)-in both mated and light-trapped females. Applying the JH analog methoprene to unmated females increased their locomotor activity and light capture rates, supporting a role for JH signaling in mediating this behavioral change.CONCLUSIONThese findings demonstrate that post-mating hormonal changes enhance female mobility, which subsequently increases their capture in light traps, establishing a mechanistic link between reproductive status and behavior.
