摘  要:
采用药膜法、滤纸药膜选择法和三角瓶药纸熏蒸法分别测定了石菖蒲根茎提取物β-细辛醚(β-asa-rone)对谷蠹(Rhizopertha dominicaFab.)成虫的触杀、驱避及熏蒸作用。结果表明,β-细辛醚对谷蠹成虫具有较好的触杀与熏蒸活性。药膜法159.20μg/cm2浓度触杀处理72 h后对试虫的校正死亡率为100.00%。滤纸药膜选择法157.30、78.65、39.33、19.66μg/cm2剂量处理72 h内的平均驱避率均≥Ⅳ级。三角瓶药纸法166.67μL/L、83.33μL/L熏蒸处理72 h后试虫的校正死亡率分别为98.20%、75.86%。

摘  要:
The contact action,repellency and fumigation action of β-asarone derived from Acorus gramineus Soland.to adult Rhizopertha dominica Fab.were studied in this paper.The result showed that β-asarone had good bioactivities to adult R.dominica.At 72 h post-treatment,the corrected mortality at 159.20 μg/cm2 was 100.00%.The repellence classes of 157.30,78.65,39.33,19.66 μg/cm2 were all higher than Ⅳ.The corrected knockdown rate of 166.67 μL/L,83.33 μL/L of β-asarone to adult were 98.20%,75.86% respectively by fumigating at 72 h post-treatment.
