Essential oil (EO), from Clausena anisata, was evaluated for their efficacy (fumigant and repellent activities) against Sitophilus oryzae. Result revealed that C. anisata showed 82% fumigant toxicity (insect mortality) at 160 μL/L concentration after 24h observation period. C. anisata exhibited LC value of 17.84 μL/L concentration for fumigant toxicity. The insect movement behaviour (repellent) was observed in two different concentrations of 10 and 50 μL for a period of 3 h. Maximum repellent activity (- 0.25) was observed at 50 μL/L concentration against S. oryzae after 3-h observation. At 3, 6 and 12 μL/L concentrations of C. anisata oil significantly reduced the protein content and total esterase activity of S. oryzae.
香茅精油（EO）从山蒟（Clausena anisata）中提取，用于评估其对米象（Sitophilus oryzae）的功效（熏蒸和驱避活性）。结果表明，在 24 小时观察期后，浓度为 160μL/L 的香茅精油表现出 82%的熏蒸毒性（昆虫死亡率）。香茅精油的 LC 值为 17.84μL/L，表现出熏蒸毒性。在两个不同的浓度（10 和 50μL）下观察到昆虫的运动行为（驱避性），为期 3 小时。在 3 小时观察后，50μL/L 浓度下对米象的最大驱避活性（-0.25）。在 3、6 和 12μL/L 浓度的香茅精油中，米象的蛋白质含量和总酯酶活性明显降低。
