【摘要】 根据昆虫病原真菌毒素的分子量和结构分为低分子量毒素和高分子蛋白毒素两大类,根据结构将低分子量毒素分为环缩肽类、色素类、有机酸类和其它类,根据功能将大分子蛋白毒素分为酶类毒素和非酶类蛋白毒素。对白僵菌素、破坏素等多种昆虫病原真菌毒素的结构和性质进行了阐述。从昆虫病原真菌产毒素的适宜培养条件到毒素的分离纯化方法、毒素毒力的生物测定和毒素的致病机理等方面的研究进展情况进行了评述。更多还原

【Abstract】 The recent research progress on the toxin of entomopathogenic fungi is reviewed. The toxins discovered can be classified in two groups according to their structure and function. One group is lowmolecularweight compounds including cyclodepsipetides, pigments, organic acids and others. The other is highermolecularweight proteins including proteases and protein toxins. Some toxins, such as, beauverin and destruxin, are listed in the paper. The culture conditions, the toxin isolation, bioassay and action mechanism are summarized.更多还原
