摘要
为探索烟草甲和嗜卷书虱的有效绿色防治方法,在实验室进行了牛尾蒿、灰苞蒿、红足蒿、白莲蒿和华北米蒿挥发油对两种仓储害虫的趋避活性试验。分别测试了5个浓度(烟草甲:78.63、15.73、3.15、0.63和0.13 nL/cm^2,嗜卷书虱:31.58、6.32、1.26、0.25和0.05 nL/cm^2)条件下5种蒿属植物挥发油対烟草甲和嗜卷书虱的趋避率,并评价了其趋避效果。结果表明:①红足蒿对烟草甲趋避活性最高,在高浓度(78.63 nL/cm^2)条件下,趋避率达98%,其次是白莲蒿和华北米蒿。其中,华北米蒿的持续作用时间较长,高测试浓度条件下作用4 h时,趋避率仍达到96%;②对嗜卷书虱而言,在较高浓度(31.58 nL/cm^2)条件下,牛尾蒿对其趋避效果最显著,达96%;③在使用浓度较低时,5种蒿属植物挥发油对两种仓储害虫的趋避作用效果均较弱。5种蒿属植物挥发油对两种仓储害虫在一定的浓度和时间内表现出明显的趋避效果。
For green control against Lasioderma serricorne and Liposcelis bostrychophila, a laboratory experiment was conducted to investigate the repellent activities of essential oils extracted from five species of Genus Artemisia(A. dubia, A. roxburghiana, A. rubripes, A. sacrorum and A. giraldii) against the two pests in stored tobacco. The repellent rates of the five essential oils were evaluated at ten test concentrations(78.63, 15.73,3.15, 0.63 and 0.13 nL/cm^2 for L. serricorne;31.58, 6.32, 1.26, 0.25 and 0.05 nL/cm^2 for L. bostrychophila). The results showed that: 1) At the concentration of 78.63 nL/cm^2, the essential oil of A. rubripes presented the strongest repellent activity against L. serricorne with up to 98% repellent rate, and this was followed by the essential oils of A. sacrorum and A. giraldii. The repellent duration time of A. giraldii essential oil was longer than the other essential oils, with its repellent rate still reaching 96% after 4 h. 2) At the concentration of 31.58 nL/cm^2, the repellent effect of A. dubia essential oil was the most significant against L. bostrychophila, its repellent rate was up to 96%. 3) The repellent effects of the five essential oils were weaker against the two pests at lower concentrations. In conclusion, the essential oils extracted from the five plants presented significant repellent effects against the two pests in stored tobacco at certain concentrations and duration.
