摘　　要：用水蒸汽蒸馏法从岭南花椒Zanthoxylum austrosinense果实、椿叶花椒Zanthoxylum ailanthoides果实和四数九里香Murraya hunanensis叶中提取植物精油,采用三角瓶密闭熏蒸法测试3种精油对家蝇的熏杀、击倒作用及其混配增效作用。3种植物精油对家蝇的6 h熏杀LC50值分别为岭南花椒果实精油7.55μg/cm3、椿叶花椒果实精油11.08μg/cm3、四数九里香叶精油11.41μg/cm3;在熏蒸浓度均为10μL/345 m L时精油对家蝇的熏蒸击倒效果KT50分别为岭南花椒果实精油16.80 min、椿叶花椒果实精油24.69 min、四数九里香叶精油23.33 min。将岭南花椒果实精油与椿叶花椒果实精油以体积比7:3和9:1混配,其共毒系数分别为130.00和136.08;将岭南花椒果实精油与四数九里香叶精油以体积比9:1混配,其共毒系数为123.71。研究结果表明,3种植物精油对家蝇均有熏杀、击倒作用,其中岭南花椒果实精油与椿叶花椒果实精油或四数九里香叶精油以适当比例混配后具有增效作用,可利用其开发高效环保的植物源灭蝇剂。Essential oils were extracted from Zanthoxylum austrosinense fruits, Z ailanthoides fruits, and Murraya hunanensis leaves by steam distillation. The fumigation insecticidal activity, fumigation knockdown effect and synergistic effects of certain mixtures of these essential oils against Musca domestica L. were tested by triangular bottle closed fumigation method. The results showed that 6-h-fumigation LC50 values of essential oils from Z austrosinense, Z ailanthoides, and M. hunanensis against M. domestica were 7.55, 11.08 and 11.41 μg/cm3, respectively. At the fumigation concentration of 10 μL/345 mL, KT50 values of essential oils from Z. austrosinense, Z. ailanthoides, and M. hunanensis against M. domestica were 16.80, 24.69 and 23.33 min, respectively. The co-toxicity coefficient of Z austrosinense oil and Z ailanthoides oil mixed at a volume ratio of 7：3 and 9：1 against M. domestica were 130.00 and 136.08, respectively. The co-toxicity coefficient of Z austrosinense oil and M. hunanensis oil mixed at a volume ratio of 9：1 against M. domestica was 123.71. The results indicate that the three essential oils possess high fumigation insecticidal activity and fumigation knockdown effect against M. domestica, and certain ratio mixtures of these oils show remarkable synergistic effect of fumigation against M. domestica. These essential oils have the potential to be developed into an effective and eco-friendly insecticide.
