This research investigates how fourth-instar larvae of the potato tuber moth, Phthorimaea operculella, respond to plant secondary metabolites (sucrose, glucose, nicotine, and tannic acid) both in terms gustatory electrophysiology feeding behavior. The objective is establish a theoretical foundation for employing plant-derived compounds moth control. We employed single-sensillum recording techniques dual-choice leaf disk assays assess electrophysiological responses preferences these towards mentioned compounds. Sensory neurons responsive sucrose, acid were identified larvae’s medial lateral sensilla styloconica. Neuronal activity was influenced by stimulus type concentration. Notably, two types styloconica displayed distinct response patterns sucrose glucose while they had similar firing nicotine acid. Sucrose significantly promoted larval feeding, significant inhibitory effects. These findings demonstrate that house sensory sensitive stimulants inhibitors, albeit with differing profiles sensitivities. study suggests are promising candidates stimulants, show potential as effective inhibitors P. operculella larvae.
