Pest behavioural disruption by plant metabolites: a crop protection challenge Plant secondary (specialized) metabolites play a pivotal role in disrupting pest behaviour, offering a promising and environmentally friendly alternative to conventional pesticides. These compounds can interfere with insect feeding, oviposition, and host selection, thereby reducing crop damage and pest populations. Recent advances highlight the ecological selectivity and rapid biodegradation of these metabolites, making them attractive for sustainable crop protection. Innovative formulation techniques are enhancing their persistence and efficacy, yet challenges remain in understanding synergistic effects, nontarget impacts, and practical implementation. Harnessing the full potential of plant metabolites for pest behavioural disruption requires integrated research and development, paving the way for their broader adoption in integrated pest management strategies.

Fig. 1.miRNAs involved in gametogenesis. The figure represents the main miRNAs involved in gametogenesis in rice. miR172 regulates floral organ development by targeting AP2. miR528 and miR2118 are implicated in pollen fertility, where miR528 represses UCL23 while miR2118 interacts with AGO1 to produce 21 nt reproductive phasiRNAs. miR5506 and miR5488 contribute to embryo sac development by regulating REM and ARF25, respectively. These regulatory networks highlight the essential role of miRNAs in coordinating reproductive success in rice.

Beyond static structure: high-throughput chemical cartography of dynamic cell wall assembly Plant cell walls are intricate, heterogeneous networks that define plant morphogenesis and biomass recalcitrance. Deciphering their chemical architecture in situ has long been hindered by the trade-off between spatial resolution and chemical specificity. Here, we introduce an integrated platform that synergizes confocal Raman microscopy (CRM) with stimulated Raman scattering (SRS) to bridge this gap. This duality is transformative: CRM captures full ‘fingerprint’ spectra to identify novel or unexpected polymers, while SRS visualizes specific chemical bonds at video-rate speeds, unlocking population-scale screening.

Photos showing the experiment setup. (A) One of the raised beds where two Vidalia onion varieties (‘Plethora’ and ‘Sapelo Sweet’) were grown together at a specific claypan (Bt soil horizon) depth and S content within the claypan (16 Dec 2021). (B) Photo of all 21 raised beds, where onions were grown with differing depths to the claypan (15 cm, 30 cm, 45 cm, and no claypan) and S content within the claypan (17 Mar 2022).

Onion roots can access sulfur deposits from as deep as 45-cm. S uptake from subsurface horizons can influence pungency and late-season S uptake from subsurface horizons can cause increased risk of high pungency. https://doi.org/10.21273/HORTSCI19034-25 #plantscience
