昆虫化学感受蛋白研究进展

昆虫化学感受蛋白(chemosensory proteins)是在长期进化过程中形成的一类低分子量酸性可溶性蛋白，广泛分布于昆虫触角、跗节等各种化学感受器中，蛋白质序列具有较高的保守性，种内种间同源性一般为30%～90％。其主要功能是感受、识别、转运、传导环境化学因子刺激信息，参与调节生理节律和生长发育。该文从昆虫化学感受蛋白的生态进化意义、分布表达部位、生化特性、分子结构、生理功能和研究方法等角度，较详细地综述了近年来国内外昆虫化学感受蛋白的研究进展，指出昆虫化学感受蛋白的深入研究，对于阐明昆虫与环境化学信息联系规律、昆虫行为反应本质原因，探索害虫综合治理和益虫利用效率新途径，开辟创制昆虫行为控制剂新领域等具有重要的理论和实践意义。

Recent advances in chemosensory proteins of insects

Chemosensory proteins (CSPs) are small soluble acidic proteins formed during long evolution and abundantly distributed in antennae, tarsi and other sensory appendages. Chemosensory proteins among insects are well conserved and the identity is generally 30%-90%. They are believed to be involved in chemical communication, including perception, identification, transport and transduction of semiochemicals from environment (including olfaction, taste and others) and may be associated with regulation of circadian rhythms and maturation of tissue or appendage. Recent advances in chemosensory proteins of insects are reviewed in this paper, including evolution significance, localization of distribution and expression, biochemical characteristics, molecular structure, physiological function and research methods. Clearly, further researches on chemosensory proteins are required, which are significant to elucidate the essence of insect behavior and semiochemicals, explore the new approach for pest management and utilization of beneficial insects, and develop new insect behavior regulators.
