| 摘 要： | 研究了核桃叶提取物及萃取物对粘虫、小菜蛾的生物活性.结果表明:核桃叶95乙醇冷提物对小菜蛾有明显的拒食作用;提取物的乙酸乙酯萃取部分对粘虫有较明显的拒食作用,且乙酸乙酯萃取物浓度的变化,对粘虫的拒食率、死亡率及生长发育抑制率均有较大影响.研究还表明:提取时所用乙醇浓度越大,提取物活性越明显,且冷提的效果较热提好.

| Abstract: | The results of this study show that the walnut leaves extract with 95% ethanol has obvious antifeeding effect on armyworm and small vegetable-moth.The fraction extracted from the extract above with ethyl acetate has more remarkably antifeeding effect on armyworm , the concentration change of extract with ethyl acetate affect antifeeding rate, death rate and growth inhibition rate. The results also indicate that the insecticide activity of the ethanol extract with difference temperature and concentrations is also different. |
