Halyomorpha halys (Stål), commonly known as the brown marmorated stink bug, is an invasive pest species that poses a significant threat to agricultural crops, especially in the hazelnut-growing regions of Türkiye. Due to the growing concern about synthetic insecticides and their negative impact on the environment, interest in plant-based alternatives has increased. The aim of this study was to investigate the insecticidal efficacy of six available plant essential oils (lemon, rosemary, nettle, bergamot, orange and basil) against the third nymphal stage and adults of H. halys under laboratory conditions. The oils were tested at five concentrations (1 %, 5 %, 10 %, 15 % and 20 %) using a direct spray bioassay method. The results showed that lemon and rosemary oil at a concentration of 20 % caused the highest mortality in both nymphs (97.36 % and 97.6 %) and adults (88.21 % and 94.74 %). In particular, nettle and orange oils showed significant mortality at concentrations as low as 1%, indicating strong bioactivity at low doses. The study suggests the potential of certain essential plant oils as environmentally friendly alternatives in integrated pest management (IPM) programs against H. halys. Further research is recommended to identify the active ingredients and verify efficacy at field level.
