中文摘要： 昆虫对外界气味的感受作用是一个庞大而复杂的体系，多种蛋白参与了这一过程。其中包括气味结合蛋白，气味结合蛋白受体，气味降解酶等多种蛋白。昆虫不仅可以通过外界气味分子携带的信息来识别配偶，天敌，还可以通过对外界环境特征的识别来寻找食物来源，产卵等。明确昆虫的化学感受机制不仅可以帮助我们理解昆虫的行为，还有助于深入了解动物的行为机制。文章综述昆虫对气味分子的识别、气味分子在昆虫体内的运输以及电化学信号传导机制等方面的进展。
英文摘要： 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.
