Blumea balsamifera (L.) DC. (Asteraceae), also known as sambong, is a perennial herb used in China for medicinal purposes. The essential oil (EO) of B. balsamifera was extracted by hydrodistillation. Thirty chemical components of the EO were analyzed by gas chromatography-mass spectrometry (GC-MS) and GC, accounting for 88.0% (w/w) of the total oil. The EO of B. balsamifera was mainly composed of monoterpenes and sesquiterpenes, in which borneol (23.3%), β-caryophyllene (20.9%) and camphor (11.8%) were the major components. The insecticidal activities of the EO and its three main compounds against Tribolium castaneum, Lasioderma serricorne and Sitophilus oryzae were evaluated. The results of bioassays displayed that the EO of B. balsamifera did not have fumigant toxicity to the three target insects, but exhibited significant contact activity against L. serricorne (LD = 12.4 μg/adult) and S. oryzae (LD = 44.4 μg/adult). Meanwhile, the EO showed a notable repellent effect on T. castaneum at all testing concentrations and a general repellent effect on S. oryzae at high concentrations (78.63 nL/cm). β-Caryophyllene showed the best performance in the contact toxicity bioassays against the three insects. The results indicated that B. balsamifera has the potential to be used as a source of botanical insecticides for the control of stored-product insects.
菊科植物艾纳香（Blumea balsamifera（L.）DC.），又名大风艾，在中国作为药用植物被广泛使用。采用水蒸馏法从艾纳香中提取精油（EO）。通过气相色谱-质谱联用仪（GC-MS）和 GC 分析了 30 种 EO 的化学成分，占总油量的 88.0%（w/w）。艾纳香精油主要由单萜类和倍半萜类组成，其中龙脑（23.3%）、β-石竹烯（20.9%）和樟脑（11.8%）是主要成分。评估了精油及其三种主要化合物对赤拟谷盗、烟草甲和米象的杀虫活性。生物测定结果表明，艾纳香精油对三种目标昆虫没有熏蒸毒性，但对烟草甲（LD=12.4μg/成虫）和米象（LD=44.4μg/成虫）具有显著的接触活性。同时，该精油对赤拟谷盗在所有测试浓度下均表现出显著的驱避作用，对米象在高浓度（78.63 nL/cm）下也表现出一般的驱避作用。β-石竹烯在对三种昆虫的接触毒性生物测定中表现出最佳性能。结果表明，艾纳香具有作为防治储粮害虫的植物性杀虫剂的潜力。
