摘要: 【目的】明确室内条件下迷迭香油和花椒油对朱砂叶螨Tetranychus cinnabarinus (Boisduval)的生物活性。【方法】采用熏蒸法和驱避法测定迷迭香油和花椒油对5日龄朱砂叶螨雌成螨的熏蒸活性、产卵抑制活性和驱避活性;并采用EthoVision XT6分析亚致死浓度下两种精油对雌成螨行为的影响。【结果】分别将5日龄雌成螨熏蒸处理12, 24和48 h后,迷迭香油对朱砂叶螨的致死率均显著高于花椒油处理组(P<0.05),且随着熏蒸时间的延长或精油浓度的升高,其熏蒸活性均增强;不同浓度的迷迭香油处理朱砂叶螨雌成螨24 h后的产卵抑制率均显著高于花椒油处理组(P<0.05)。迷迭香油和花椒油处理朱砂叶螨雌成螨24 h的LC30分别为6.731和120.142 μL/L;迷迭香油对朱砂叶螨雌成螨的驱避活性明显高于花椒油处理组。两种精油亚致死浓度处理朱砂叶螨雌成螨后,其自发运动方式发生了明显变化,移动频率在LC10 时呈现最高;且迷迭香油对朱砂叶螨雌成螨自发运动能力的影响比花椒油处理的影响更为明显。【结论】迷迭香油对朱砂叶螨的生物活性明显高于花椒油,因此,迷迭香油对朱砂叶螨的生物防治具有较高的应用价值。本研究为绿色蔬菜植物源杀螨剂的研究提供了科学依据。

Abstract: 【Aim】 This study aims to clarify the bioactivities of rosemary and zanthoxylum oils against the carmine spider mite, Tetranychus cinnabarinus (Boisduval), in the laboratory. 【Methods】 The fumigation activities, oviposition inhibition activities and repellency activities of rosemary and zanthoxylum oils against the 5-day-old female adults of T. cinnabarinus were detected by the methods of fumigation and repellency. By using EthoVision XT6, the effects of the two essential oils on the behavior of T. cinnabarinus were analyzed at the sublethal concentrations. 【Results】 The mortalities of female adults of T. cinnabarinus fumigated by rosemary oil were significantly higher than those by zanthoxylum oil at 12, 24 and 48 h after exposure (P <0.05). Moreover, as the fumigation time or the concentration of the two essential oils increased, the fumigation activities were enhanced. At 24 h after treatment, the oviposition inhibition rates of female adults of T. cinnabarinus exposed to the rosemary oil were significantly higher than those exposed to the zanthoxylum oil at different concentrations ( P <0.05). After 24 h of exposure, the LC30 values of rosemary and zanthoxylum oil against female adults of T. cinnabarinus were determined to be 6.731 and 120.142 μL/L, respectively. The repellency activities of the rosemary oil against female adults of T. cinnabarinus were higher than those of zanthoxylum oil. When the female adults of T. cinnabarinus were treated by the two essential oils at the sublethal concentrations, their spontaneous movement tracks changed significantly and the mobility frequencies were the highest at the LC10. Moreover, the spontaneous movement abilities of female adults of T. cinnabarinus were more obviously affected by rosemary oil than by zanthoxylum oil. 【Conclusion】 The bioactivities of T. cinnabarinus induced by the rosemary oil were significantly higher than those induced by the zanthoxylum oil. Therefore, rosemary oil has higher application value in the biological control of T. cinnabarinus. This study provides a scientific basis for the development of botanical acaricides for green vegetables.
