Hedychium coronarium, commonly referred to as the white ginger lily, is esteemed for its ornamental characteristics and fragrant properties. However, its potential as a natural insecticide remains inadequately explored, particularly regarding the influence of seasonal variations on its chemical composition. The aim of this study was to investigate the insecticidal and nematicidal properties of H. coronarium oleoresins in different seasons and to shed light on their efficacy as biopesticides. The crude oleoresins were extracted using the cold percolation method and subsequently analyzed for total phenolic content (TPC), total flavonoid content (TFC) and ortho-dihydric phenolics. The biological activities of the oleoresins were tested against the root-knot nematode, Meloidogyne incognita and the insect pest, Spodoptera litura. Results indicated significant seasonal variations in the chemical composition of the phenolic compounds. The oleoresins exhibited notable nematicidal activity across all seasons, alongside promising insecticidal effects against S. litura. These findings suggest that fluctuations in the concentrations of bioactive compounds are responsible for the observed variations, emphasizing the importance of considering seasonal dynamics in the development of H. coronarium-based insecticides for integrated pest management strategies.
