宇尾谆子(1971)报道,从哺乳动物牛、猪和鼠脑中分离出昆虫脑激素类似活性物质,能使人工去脑的天蚕蛾蛹羽化。由此可见,高等哺乳动物的脑激素对昆虫是有效应的。另一方面,从石炭纪以来,昆虫就同植物依存而进化,所以昆虫和植物之间又有深远的化学联系。到目前为止,已发现有一千多种植物含有昆虫激素类似物,包括保幼激素、蜕皮激素、抗保幼激素(又名早熟素)、抗蜕皮素及昆虫性信息素等。因此,昆虫激素、其它动物激素和植物激素之间,可能存在某种相关性或有类 Utsuko (1971) reported that insect-derived brain hormone-like actives were isolated from mammalian cattle, pigs, and rat brains, enabling the emergence of artificially degenerated pupae. Thus, brain hormones in higher mammals are effective for insects. On the other hand, since the Carboniferous, insects evolved on the same plant, so there was a profound chemical connection between insects and plants. To date, more than a thousand species of plants have been found to contain insect hormone analogs, including juvenile hormones, ecdysone, juvenile hormone (aka precocious hormone), ecdysone and insect pheromone. Therefore, there may be some correlations or similarities between insect hormones, other animal hormones and plant hormones
