中文摘要：
采用滤纸药膜选择法研究了蛇床子、茵陈、萹蓄等12种药用植物乙醇提取物对谷蠹Rhizopertha dominica (Fab.)和赤拟谷盗Tribolium castaneum Herbst成虫的驱避效应。12种药用植物以蛇床子(Cnidium monnieri)提取物对谷蠹成虫的驱避效果最佳，786 μg/cm2处理24 h对谷蠹的驱避率达93%；茵陈(Artemisia capillaries)提取物对赤拟谷盗成虫的驱避效果最佳，用393 μg/cm2处理72 h的驱避率为95%，茵陈提取物以262 μg/cm2放置7 d后对赤拟谷盗成虫的驱避率可达Ⅴ级水平。茵陈提取物对赤拟谷盗的驱避持效期长、效果好，具有一定的开发前景。
英文摘要：
The repellent effect of ethanol extracts from 12 herb plants on the adults of Rhizopertha dominica (Fab.) and Tribolium castaneum Herbst was studied using dual-|selection tests with filter paper immersion. Of all 12 herb plants, the extract from Cnidium monnieri showed best repellent effect on R. dominica, in which 786 μg/cm2 extract got 93% repelling rate at 24 h post-treatment. The extract from Artemisia capillaries had best repellent effect on T. castaneum, in which 393 μg/cm2 extract got 95% repelling rate at 72 h post-treatment accordingly. When stored for 7 days at 262 μg/cm2, the repellent action of the extract from A. capillaries to T. castaneum adults reached grade V. The extract from A. capillaries had certain value for further exploration because of its good repellent effect on T. castaneum.
