Regulation of feeding behaviors by key sugar and bitter gustatory receptors in Helicoverpa armigera

These results indicate that Gr10 is crucial for larvae and Gr6 for adults in tasting some palatable foods, while Gr180 is important for both larvae and adults in avoiding some unpalatable foods. These findings enhance the understanding of how feeding behavior is controlled by taste neuron input in this polyphagous moth species. © 2025 Society of Chemical Industry.
