Abstract: Olfaction plays pivotal roles all over the life span of insects, providing insects with information essential for survival and reproduction. In spite of structural and functional diversities driven by selection, olfactory systems share a common coding principle in information perception and processing. Here we review the key nodes and corresponding relationships of peripheral and central nervous system across many insect species, and aim to identify the basic principles of olfactory circuit. Moreover, we present comparative analyses of some insects to show unexpected cases, and provide a new insight in the functions and evolution of insect olfaction.
