天然除虫菊素除虫菊是一种多年生草本植物,属菊科(Compo-site),菊属(Chrysantbemum)。菊属的品种很多,其中若干种的花中含有杀虫物质,又以白花除虫菊(Chrys-anthemum Cineriaefolum)或称瓜叶除虫菊含有的杀虫物质——除虫菊素最多。早在十七世纪时,除虫菊已在波斯大量栽植;1840年,在南斯拉夫发现有白花除虫菊品种。目前,在靠近赤道的非洲国家种植较多。我国在1935年开始有栽培数量的记载,迄今仍有栽植。

Currently, more are planted in African countries near the equator. Since 1935, China began to record the amount of cultivation and so far it has been planted.
