Electrophysiological and behavioral responses of fourth instar spotted lanternfly nymphs to hexanal

Year: 2025

Type: article

Abstract: ) is an invasive, polyphagous planthopper. We previously identified an olfactory organ on the labium in adults; here, we show that fourth instar nymphs possess a similar organ. This organ consists of two placoid sensilla, each housing two olfactory receptor neurons: one tuned to hexanal and the other to methyl salicylate. We also found that 10 µl of pure hexanal elicits strong attraction in nymphs. These results highlight the olfactory capabilities of SLF nymphs and identify hexanal as a potential attractant that could aid in monitoring and management of this insect.
