摘  要：
采用药膜法和滤纸药膜选择法,分别研究了20种药用植物乙醇提取物对谷蠹Rhizopertha dominica(Fab.)成虫的触杀和驱避活性。结果表明:触杀效果以葫芦巴Trigonelia foenum-graecum提取物的活性最强,蛇床子Cnidiummonnieri和石菖蒲Acorus gramineus提取物次之。葫芦巴提取物0.39mg/cm2浓度处理48h后对谷蠹的触杀死亡率为100%,处理72h后对谷蠹的LD50为19.94μg/cm2。蛇床子和乌头Aconitum carmichaeli提取物对谷蠹成虫具有显著的驱避活性。蛇床子提取物同时具有较好的触杀和驱避活性。

摘  要：
In this paper we reported the bioactivities of ethanol extracts from 20 medicinal plants against Rhizopertha dominica (Fab.) using drug-film method and filter paper diffusion method. The results of the contact tests showed that the extract of Trigonelia foenum-graecum was most effective on the pest, followed by Cnidium monnieri and Acorus gramineus respectively. At 0.39 mg/cm2 treatment, T. foenum-graecum extract showed 100% mortality at 48 h post-treatment. C. monnieri and Aconitum carmichaeli had marked repellence effect against R. dominica. C. monnieri extract had better contact and repellence efficacy. The LD_ 50 of T. foenum-graecum plant extract against R. dominica after 72 h treatment was 19.94 μg/cm2.
