Chemosensation and mechanosensation are vital to insects’ survival behavior, shaping critical physiological processes such as feeding, metabolism, mating, reproduction. During insects rely on diverse chemosensory mechanosensory receptors distinguish between nutritious harmful substances, enabling them select suitable food sources while avoiding toxins. These distributed across various body parts, allowing detect environmental cues about quality adjust their behaviors accordingly. A deeper understanding of insect sensory physiology, especially during not only enhances our knowledge biology but also offers significant opportunities for practical applications. This review highlights recent advancements in research feeding-related receptors, covering a wide range species, from the model organism Drosophila melanogaster agricultural human pests. Additionally, this examines potential targeting precision pest control. Disrupting feeding reproduction emerges promising strategy management. By interfering with these essential behaviors, we can effectively control populations minimizing impacts promoting ecological balance.

ABSTRACT Artificial sweeteners are highly sweet, non-nutritive compounds that have become increasingly popular over recent decades despite research suggesting their consumption has unintended consequences. Specifically, there is evidence some of these chemicals interact with bitter taste receptors, implying likely generate complex chemosensory signals. Here, we report the basic sensory characteristics in Drosophila , a common model system used to study impacts diet, and find all noncaloric inhibited appetitive feeding responses at higher concentrations. At cellular level, found sucralose rebaudioside A co-activated sweet gustatory receptor neurons (GRNs), two populations reciprocally impact behavior, while aspartame only activated cells. We assessed behavioral co-activation low concentrations signal high aversion. Finally, silencing GRNs reduced aversive elicited by significantly increased behaviors. Together, conclude artificial more than “sweetness” alone, this behaviorally relevant effects on may help flies flexibly respond unique compounds.

Abstract Our sense of taste is critical for regulating food consumption. The fruit fly Drosophila represents a highly tractable model to investigate mechanisms processing, but circuits beyond sensory neurons are largely unidentified. Here, we use whole-brain connectome the organization circuits. We trace pathways from four populations that detect different modalities and project subesophageal zone (SEZ), primary region brain. find second-order primarily located within SEZ segregated by modality, whereas third-order have more projections outside overlap between modalities. Taste out innervate regions implicated in feeding, olfactory learning. analyze interconnections pathways, characterize modality-dependent differences neuron properties, identify other types inputs onto computational simulations relate neuronal connectivity predicted activity. These studies provide insight into architecture
