Abstract： Ordor perception of insects is a large and complex system, involving many kinds of proteins such as odorant binding proteins, odorant receptor and odorantdegrading esterase etc. Insect perceive the external environment through small odorants which carry information (signature) of potential mates, prey, food sources, oviposition sites, etc. Revealing the mechanism of odor perception in insects will result in a deeper understanding of insect behaviour. The progress on odorant recognition, odorantreceptor interaction at the molecular level and the mechanism of electricalchemo signal transduction were reviewed in this paper.
