| 摘 要： | 测定了宁夏地区分布的82种植物丙酮提取物对小菜蛾(Plutella xylostella)幼虫的生物活性.结果表明,对小菜蛾具有50%以上毒杀活性的植物有8科8种,具有20%~50%毒杀活性的植物有16科25种;具有50%以上拒食活性的植物有10科18种.经综合分析,认为豆科、菊科、萝藦科、毛莨科和茄科等科植物具有较好的研究开发价值.

| Abstract: | The bioactivities of the acetone extracts of 82 plants collected from Ningxia were tested with the 3rd instar of Plutella xylostella in this paper.The results showed that 8 species of 8 families have more than 50% mortality,and 25 species of 16 families have mortalities from 20% to 50%.The results also indicated that 18 species of 10 families have more than 50% antifeedent activity.It was proved that Leguminosae,Compositae,Asclepiadaceae,Ranunculaceae and Solanaceae were worth developing. |
