STUDIES ON INSECTICIDAL ACTIVITY OF THE ESSENTIALOIL FROM Clausena dunniana AND ITS TOXIC COMPONENT

摘要: 生物测定表明，齿叶黄皮精油对仓库害虫具有较好的防治作用。使用２０ｍｇ／Ｌ剂量进行熏蒸或０．２％剂量拌种都能有效地杀灭赤拟谷盗成虫或抑制其种群繁殖。采有柱层析法分离得到齿叶黄皮精油主成分──爱草脑的纯品。活性跟踪试验确证爱草脑为齿叶黄皮精油的有效杀虫成分。

Abstract: ResuIts of bioassays showed that the essential oils from Clausena dunnianawas very effective against stored product insects,Sitophilus zeamais and otherspecies.It caused 99.33 % of mortality and completely inhibited the reproduction ofred flour beetle(Tribolium castaneum)when was used for fumigation at a dosage of20 mg/L,or mixed with wheat flour at a concentration of 0.2% by weight.Estragole,the predominant component of the essential oil,was isolated by means of columnchromatography and proved to be the insecticidal component of this plant by aseries of bioassays.
