The tomato leaf miner, Tuta absoluta, is a pest threatening global production. This pest’s adaptability and resistance to chemical insecticides have necessitated integrated management (IPM) strategies prioritizing sustainable alternatives. review explores the role of biological control agents (BCAs) in managing T. absoluta populations, emphasizing integration floral resources enhance their efficacy. Predatory mirids such as Macrolophus pygmaeus Nesidiocoris tenuis parasitoids N. artynes Trichogramma spp. are pivotal suppression; however, performance depends on nutritional habitat support. Floral provide essential sugars proteins, improving longevity, fecundity, predation efficiency these BCAs. synthesizes case studies highlighting benefits selected flowering plants, Lobularia maritima Fagopyrum esculentum, supporting predator parasitoid populations while minimizing advantages absoluta. Mechanisms nectar quality, accessibility, spatial–temporal resource availability explored detail. Additionally, challenges selective attraction, microbial impacts composition, unintended support non-target organisms discussed. proposes targeted optimize BCA within IPM systems by integrating ecological insights. approach offers pathway toward reducing pesticide reliance, fostering agriculture, mitigating economic infestations.

Terrestrial plants naturally produce chemical signals to attract beneficial insects or repel harmful pests. These inherent plant attributes offer promising opportunities for eco-friendly pest control in agriculture, particularly through the push-pull intercropping technique. However, our understanding of potential repellent and their effective remains limited. In this study, we evaluated multiple species properties, identified volatile organic compounds, investigated mechanisms controlling fungus gnat Bradysia odoriphaga Chinese chives. Among 12 tested, Mentha haplocalyx, Ocimum basilicum Pelargonium graveolens demonstrated strong effects, making them candidates as 'push' plants. Eight major compounds were repellents, with 1,8-cineole being most efficient. consistently exhibited effects against gnats across various concentrations exposure durations. Transcriptomic analysis revealed that upregulated genes is associated energy production processes, suggesting can detect actively avoid compound. Field experiments further confirmed effectiveness strategy, chives M. haplocalyx significantly reduced infestations. This study presents a novel approach managing offers valuable insights into sustainable management practices agriculture.

Common bean production is crucial in Western Kenya due to its economic, nutritional, environmental, and cultural importance. However, challenges such as diseases, especially viral cause significant crop losses. This study sought identify potential biomarkers for BCMV BCMNV diseases by analyzing small molecule metabolites diseased common systems gain an understanding of related metabolic pathways. Virus-free Rosecoco cultivars were planted exposed specific regions, with healthy plants serving controls. Diseased leaves collected metabolite extraction analyzed using liquid chromatography mass spectrometry. A total 354 identified across seven pathways, 51 upregulated metabolites, primarily from fatty acids, terpenoids, alkaloids. Ten differentially expressed, the molecular structures two successfully determined. These serve disease detection, monitoring, resistance beans. The findings highlight role acids well importance regional variability plant hormone regulation response stress, suggesting that further research into these pathways will be essential defense mechanisms.

As global climates shift, plants are increasingly exposed to biotic and abiotic stresses that adversely affect their growth development, ultimately reducing agricultural productivity. To counter these stresses, produce secondary metabolites (SMs), which critical biochemical essential compounds serve as primary defense mechanisms. These diverse compounds, such alkaloids, flavonoids, phenolic nitrogen/sulfur-containing act natural protectants against herbivores, pathogens, oxidative stress. Despite the well-documented protective roles of SMs, precise mechanisms by environmental factors modulate accumulation under different stress conditions not fully understood. This review provides comprehensive insights into recent advances in understanding functions SMs plant emphasizing regulatory networks biosynthetic pathways. Furthermore, we explored unique contributions individual SM classes responses while integrating findings across entire spectrum diversity, providing a resilience multiple conditions. Finally, highlight emerging strategies for harnessing improve crop through genetic engineering present novel solutions enhance sustainability changing climate.
