The Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) is a globally invasive pest, and its management is primarily dependent on chemical pesticides, which has spurred the need for eco-friendly control strategies. The push–pull strategy, an environmentally friendly pest management approach, has shown promise in controlling S. frugiperda . In this study, using a combination of adult oviposition, larval feeding, and electrophysiological tests, we confirmed the repellent properties of coriander and its volatiles. Gas chromatography–mass spectrometry analysis of coriander volatiles revealed E -2-decenal as the major repellent compound. Furthermore, SfruOBP13 was identified as one of the main odorant-binding proteins that detects E -2-decenal in the S. frugiperda, providing a molecular basis for the insect’s perception of this volatile. These findings lay the groundwork for developing behavior-based pest control strategies, offering valuable insights for sustainable S. frugiperda management using plant-derived semiochemicals.
