摘要: 本实验研究了不同溶剂对花椒挥发油的提取效果,进行了花椒挥发油对不同菌种的抑菌实验,并探究了其对棉铃虫幼虫的拒食性和忌避性。实验结果表明:当乙醚作为提取剂时,提取率最高为8.77%;对不同菌种的抑菌效果无明显差别;乙醚提取的花椒挥发油对棉铃虫幼虫在拒食率及忌避率上均优于其他溶剂所提取的挥发油,对棉铃虫幼虫有着更好的抑制力。

Abstract: Extraction effects of volatile oil from Zanthoxylum by different solvents were studied,then the experiment of its antibacterial activity was conducted,and the antifeeding and repellency of cotton bollworms to volatile oil from Zanthoxylum were investigated. The results of the experiment were as follows,the best extraction rate was 8.77% while using ether as solvent,and there was no significant difference on antibacterial activity between strains. The extracted volatile oil from Zanthoxylum by ether showed priority on antifeeding and repellency of cotton bollworm larvae than those by other solvents,thus it should have better inhibitory effects on the larvae.

Key words: volatile oil, cotton bollworms, antifeeding, repellency, antibacterial activity
