昆虫信息化合物的筛选及鉴定技术研究进展

Research progress on screening and identification techniques of insect semiochemicals

在化学生态学领域中,触角电位仪(EAG)、气相色谱-触角电位联用仪(GC-EAD)、气相色谱-质谱联用仪(GC-MS)、单感器记录仪(SSR)和气相色谱-单感器记录联用仪(GC-SSR)是开展昆虫信息化合物的鉴定及活性组分筛选的重要技术手段,常用于昆虫对信息化合物感受机制、昆虫与植物的互作关系研究。本文详细分析了这几种技术的作用机理,综述了近些年昆虫电生理技术的应用和研究进展,可为昆虫信息化合物的研究提供技术参考。

In the chemical ecology field,electroantenno graphy(EAG),gas chromatography-electroantennographic detection(GC-EAD),gas chromatography-mass spectrometer(GC-MS),single sensillum recordings(SSR),and gas chromatography-single sensillum recordings(GC-SSR)play significant roles in the identification,screening of insect infochemicals and are widely used in chemoreception mechanism of semiochemical,and the investigation of the interactions between insects and plants.Here,the functions and mechanisms of the five above-mentioned technologies were expounded,their applications were summarized,and will provide technical references for the research of insect semiochemicals from the perspective of chemecology.
