植物光敏毒素以其高效、安全、易降解、商业上可大量得到、经济、有工业开发前途以及得到公众认可等特点 ,成为合成杀虫剂的替代物前景广阔。已知植物光敏毒素包括聚酮化合物、肉桂酸衍生物、生物碱、卟啉等。并阐述了光敏毒素的光化学作用方式与机制 ,及其对昆虫的影响 ,从而展示了光敏毒素杀虫剂的应用前景 ,基本对α -T进行了详细的阐述。 Because of its characteristics of high efficiency, safety, biodegradability, availability in commercial terms, economy, industrial development prospect and public recognition, plant phototoxin has a bright future as a substitute for synthetic insecticides. Plant photo-sensitive toxins are known to include polyketides, cinnamic acid derivatives, alkaloids, porphyrins and the like. The mechanism and mechanism of photochemical action of phototoxin and their effects on insects were also described. The application prospect of phototoxic insecticides was demonstrated, and α -T was described in detail.
