Research Advance of Olfactory Proteins and Olfactory Mechanism in Insects
The olfaction is one of the basis of behaviors in insects. A complex olfactory system has been formed in the long-term evolution of insects. To complete this process, a variety of odor-related proteins are needed. These include odorant binding proteins, chemosensory proteins, odorant receptors, sensory neuron membrane proteins and so on. The olfactory mechanism of insects will help us to understand their behaviors, which include identifying spouse or natural enemies, finding food sources and the place for spawning and so on. It will lay the foundation of further regulation of insect behaviors and pests prevention, protection and use of beneficial insects. In this paper, thus, we summarized these odor-related proteins and their biochemical properties, physiological functions and identi-fication mechanisms of odor molecules and also the transportation mechanisms of these molecules in insects.
