摘　　要：在160μl/L的剂量下,测试红桔油、红河橙油、柠檬叶油、黄樟油、山苍子油、蓝桉叶油、大叶留兰香油、松节油及互叶百千层油等9种植物精油对谷蠹RhyzoperthadominicaF.成虫的熏蒸活性,结果表明蓝桉叶油、柠檬叶油、互叶百千层油及红桔油等4种植物精油效果较好,24h熏蒸处理时间谷蠹成虫的校正死亡率均在50%以上;而蓝桉叶的效果则明显高于其他几种精油,校正死亡率达到96.67%,36h以后校正死亡率达到100%。60h时,蓝桉叶油、红桔油、互叶百千层油对试虫的熏蒸校正死亡率达到100%。蓝桉叶油对谷蠹成虫的熏蒸毒力测定结果表明,当熏蒸处理24h,36h,48h,60h及72h时,其LC50值分别为35.91μL/L,31.05μL/L,23.81μL/L,19.74μL/L及14.22μL/L。The fumigation activity of 9 plant essential oils against Rhizopertha dominica F. was investigated. At a dosage of 160 μL/L, the essential oils of Eucalyptus globules, Citrus imonum, Melaleuca alternifolia and C. tangerine showed high mortality of R. dominica adults with an exposure time of 24 hours. The essential oil of E. globules appeared to be the best, giving a mortality of 96.67% and 100% with an exposure time of 24 and 36 h, respectively. The LC_(50) of the pest fumigated with E. globules oil for 24, 36, 48, 60 and 72 h. Was (35.907), 31.050, 24.067, 23.396 and 20.420 μL/L, respectively.
