Abstract BACKGROUND Plants emit volatile organic compounds (VOCs), which serve as critical cues for herbivorous insects to locate hosts feeding and oviposition. Understanding how adults identify host plants is essential develop pest management strategies, particularly hemiedaphic like click beetles, the larvae of are significant soil‐dwelling pests. To investigate beetle attraction towards plant VOCs their relevance oviposition, we tested attractiveness constitutive (emitted by intact plants) damage‐induced (released chopped from 11 species male female Agriotes sputator beetles. RESULTS beetles exhibit species‐specific olfactory preferences, influenced sex maturity differ between VOCs. Female showed greatest buckwheat VOCs, especially during main oviposition period, whereas males were more attracted clover ryegrass. EAG recordings show strong antennal responses ryegrass, carrot, maize, wild barley, while antennae responded significantly only peas. Antennae overall stronger than those ( P = 0.02). CONCLUSION These findings facilitate development new approaches management. preferred aids in identifying attractive semiochemicals that can be used monitoring Additionally, recognizing wireworm either avoiding them crop rotations before sensitive crops (thus reducing oviposition) or attracting specific areas where they targeted control measures. © 2025 The Author(s).
