中文摘要:
      分别采用喷雾法和半叶法测定了11种植物精油对茶橙瘿螨的触杀和驱避活性。结果表明, 浓度为1%、0.5%、0.25%、0.125%(V/V)的11种植物精油对茶橙瘿螨都表现出了不同程度的触杀活性。随着作用时间的延长和精油浓度的增加, 其校正死亡率均有不同程度的升高。总体来看, 肉桂精油触杀效果最好, 在不同试验浓度和处理时间条件下校正死亡率均高于其他精油。所试精油对茶橙瘿螨都有一定的驱避作用, 其中百里香等8种精油的驱避率达80%以上。以上结果将为筛选对茶橙瘿螨具有较好防效的新型低毒高效植物源农药提供重要依据。
英文摘要:
      Contact and repellent activities of 11 kinds of plant essential oils against Acaphylla theae were investigated using spray method and half-leaf method, respectively. The results showed that the 11 candidates showed various degrees of contact activity at all the experimental concentrations, including 1%, 0.5%, 0.25%, and 0.125% (V/V). Particularly, the corrected mortality of each treatment gradually increased accompanying with the prolongation of treatment duration and the increase of essential oil concentration. Overall, cinnamon essential oil had the best contact-killing effect, and the corrective mortality at each concentration and time point was also higher than that of other essential oils. Moreover, all the selected plant essential oils showed certain levels of repellency activity to A.theae. Particularly, 8 kinds of essential oils including thyme essential oil have repellency activity with the efficacy of over 80%. All the results provide valuable evidences for the screening of new green pesticides with high effect and low toxicity in tea production in future.
