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.

Abstract Establishing transepithelial ion disparities is crucial for sensory functions in animals. In insect organs called sensilla, a potential, known as the sensillum potential (SP), arises through active transport across accessory cells, sensitizing receptor neurons such mechanoreceptors and chemoreceptors. Because multiple are often co-housed share SP, niche-prevalent overstimulation of single can compromise neighboring receptors by depleting SP. However, how depletion prevented to maintain homeostasis remains unknown. Here, we find that Ih- encoded hyperpolarization-activated cyclic nucleotide gated (HCN) channel bolsters activity bitter-sensing gustatory (bGRNs), albeit acting sweet-sensing GRNs (sGRNs). For this task, HCN maintains SP despite prolonged sGRN stimulation induced diet mimicking their sweet feeding niche, overripe fruit. We present evidence Ih -dependent demarcation excitability implemented throttle consumption, which may have facilitated adaptation sweetness-dominated environment. Thus, expressed sGRNs serves key component simple yet versatile peripheral coding regulates bitterness optimal food intake two contrasting ways: sweet-resilient preservation bitter aversion previously reported sweet-dependent suppression taste.

Learning, memorizing, and recalling of potential ovipositing sites can influence oviposition preference. Classical conditioning experiments have shown that vinegar flies learn the association olfactory, gustatory, or visual stimuli with either positive negative unconditioned stimuli. However, less is known about whether similar associations are formed in an ecologically more relevant context like during oviposition. Our reveal

Abstract Food choice is an important driver of speciation and invasion novel ecological niches. However, we know little about the mechanisms leading to changes in dietary preference. Here, use three closely-related species Drosophila sechellia , D. simulans melanogaster study taste circuit food evolution. sechellia, a host specialist, feeds exclusively on single fruit ( Morinda citrifolia noni) - latter two are generalists living various substrates. Using quantitative feeding assays, recapitulate preference for noni detect conserved sweet but altered bitter sensitivity via calcium imaging peripheral neurons. Noni surprisingly activates sensing neurons more strongly due small deletion one gustatory receptor. volumetric ventral brain, show that instead physiology, species-specific processing sugar signals sensorimotor circuits recapitulates differences Our data support receptor alone cannot explain rather modifications how sensory information transformed into motor commands.

Abstract Deciding where to lay an egg is critical for the survival of insects' offspring. Compared with our understanding chemosensory assessment egg‐laying sites, mechanisms texture detection are largely unknown. Here, we show that Bactrocera dorsalis , a notoriously agricultural pest laying its eggs within ripening fruits, can discriminate substrate during process. Exposure drugs targeting transient receptor potential vanilloid (TRPV) mechanosensory channels abolished their oviposition preference hard textures. BdorNan and BdorIav two members TRPV subfamily, transcripts were detected in labellum, foreleg tarsi ovipositor. Then, successfully obtained knockout strains each gene using CRISPR/Cas9 technique. The results showed required discrimination stiffness difference. had no significant effect on ability B. choose harder substrates. Our study thus reveals plays substantial role behaviour .
