| 摘 要： | 对核桃青皮中次生物质的杀虫活性研究,结果表明:核桃青皮95%乙醇粗提物及其乙酸乙酯萃取部分对粘虫有较明显的拒食作用,且乙酸乙酯萃取部分有明显的胃毒作用。但对小菜蛾而言,石油醚萃取物和乙酸乙酯萃取物的拒食作用不如对粘虫作用明显。研究还表明,随乙酸乙脂萃取物浓度的变化,粘虫的拒食率、死亡率及生长发育抑制率都会有相应变化。且随着萃取物浓度的增加,对粘虫的拒食作用增强。

| Abstract: | The green walnut hull extract with 95% ethanol and the fraction extracted from the extract above with ethyl acetate have obvious anti-feeding effect on armyworm and small vegetable-moth,and the fraction has obvious stomach poisoning effect.On contrast,the anti-feeding effects of the extracts from petroleum ether and ethyl acetate to small vegetable-moth are smaller than those to armyworm.The results also indicate that anti-feeding rate and death rate as well as growth inhibition rate of armyworm have correspondingly changed with the concentration change of the extract: the higher the concentration of extracts applied on armyworm,the bett the anti-feeding effect. |
