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.
