摘要
通过苍耳不同溶剂提取物对蚜虫和粘虫的杀虫活性测定,证明不同提取溶剂所得苍耳提取物杀虫活性差异显著.各作用方式的杀虫结果表明:苍耳各提取物对粘虫具有很强的拒食活性,对蚜虫的活性较低;同时表明,苍耳的氯仿提取物杀虫活性最好.
The insecticidal activity of the different extracts of Xanthium sibiricum on Mythimnaseparata and aphis is studied. It has highest antifeeding activity that extracts of Xanthium sibiricum on Mythimnaseparata, but it is lower that the insecticidal activity of extracts of Xanthium sibiricum on aphis. And the insecticidal activity of acetones extraction is best than others.
