| 摘 要： | 用苦树根皮粉对8种农业害虫进行的室内试验结果表明,苦树对不同的昆虫具有不同的效应:对蝗虫(成虫和若虫)、芜菁叶蜂(幼虫)具有强烈的拒食作用,对菜青虫和粘虫、稻苞虫、棉小造桥虫幼虫具有可逆的麻醉作用,但在试验中未观察到对小地老虎幼虫有麻醉作用;苦树对玉米象则表现抑制繁殖的作用。在夏甘蓝和冬甘蓝上进行的防治试验说明,适时施苦树根皮粉一次即可有效地控制菜青虫危害。其原因一方面是因麻醉作用,导致菜青虫饥饿死亡,减少了菜青虫数量,尤其是4～5龄幼虫数量,另一方面则因菜青虫未死前常处于麻醉状态而失去了取食为害的机会.

| Abstract: | According to laboratory bioassay,the root-bark powder and its et-hanol extracts of Celastrus angulota was proved to have:strong antifeeding action to the adults and nymphs of Locusta migratoria manilensis Mever and the larvae of Athalia rosae japanensis (Rhower);narcotic action to the larvae of Mythimna separata Walker,Pieris rapae L.,Parnara guttata Br. and Anomis flava Fabr.,and also effects of inhibiting reproduction to Sitophilus zeamais Mostchulsky. |
