Feeding behavior is crucial to the survival in animals. Similar to other animals, the feeding process of insects could be divided into several stages: the generation of feeding motivation, the foraging behaviors for food source, the perception of food nutrition, and the intaking of foods. The behavior of each stage is regulated by the corresponding nervous system, which guide the obtaining of desirable foods and the maintaining of the balance between nutrition obtaining and metabolism. As a result, the growth, development, reproduction and other life activities of insects could be promoted. In this review, the latest research progress of the neural mechanism of insect feeding behavior regulation in different feeding stages was summarized, aiming to provide supports for the deep study of the neural mechanism of insect feeding regulation and then develop new pest control technologies based on insect feeding regulation.
