俄罗斯专家研究发现,一些菊科植物所含的早熟素可以破坏蝗虫、蚜虫的保幼激素和多个器官的机能,有效抑制害虫的生长发育,而且不会对蜜蜂等益虫产生害处。俄科学院谢韦尔佐夫生态与进化研究所专家在实验中用紫花霍香蓟和法色草的叶子喂食蝗虫和蚜虫的幼虫,结果这些幼虫不是死掉就是过早化蛹,而过早化蛹的幼虫长大后无法繁殖。进一步的研究发现,这些植物中含有的早熟素如 Russian experts found that some precocious plants contain precocious elements that can destroy locusts, juvenile hormones and the function of multiple organs of aphids, effectively inhibiting the growth and development of pests, and will not harm bees and other beneficial insects. Experts from the Institute of Ecology and Evolution at the Russian Academy of Sciences in Chevroletz fed larvae of locusts and aphids with the leaves of Volatile Artemisiae annuus and Phascolostrina in experiments. As a result, these larvae either died or prematurely pupae, prematurely pupating Larvae grow up unable to breed. Further research found that these plants contain precocious elements such as
