<正>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。

Plant phototoxins have recently become many new sources of insecticidal compounds of their effectiveness,safety,degradability,availability in commercial quantities,economy,industrial development and acceptability to the public.Naturally occurring phototoxins mostly include polyketides,cinnamate derivatives,alkaloids and porphyrins.The photochemical mode of action and mechanism of phototoxins and their effects on insects were reviewed in this article,and then the potential application of the phototoxins was showed, in which α-T has been evaluated in detail.
