AI Article Synopsis
- - Nutrient uptake and digestion in insects are crucial for growth and development, regulated by the gut-brain axis that ensures gut balance through neurohumoral communication.
- - The insect gut has three parts—foregut, midgut, and hindgut—each with specific functions shaped by various neuropeptides that influence digestion and gut activity.
- - The review highlights key neuropeptides involved in gut physiology and explores both well-studied and less understood neuropeptides, suggesting potential applications for pest management.
Article Abstract
Nutrient uptake and digestion are essential for optimal growth and development. In insects, these processes are regulated by the gut-brain axis, which is a neurohumoral communication system for maintaining gut homeostasis. The insect gut is a complex organ consisting of three distinct structures, denominated foregut, midgut and hindgut, each with their specific specializations. These specializations are tightly regulated by the interplay of several neuropeptides: a versatile group of signalling molecules involved in a multitude of processes including gut physiology. Neuropeptides take part in the regulation of gut processes ranging from digestive enzyme release to muscle activity and satiety. Some neuropeptide mimetics are a promising strategy for ecological pest management. This review focuses on a selection of neuropeptides that are well-known for their role in gut physiology, and neuropeptides for which the mode of action is yet to be unravelled.
