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
