Abstract

Abstract:

【Objective】This study aims to investigate the selective behavioral response of Orchestes steppensis to five Ulmus (elm) leaf species and analyze the volatile composition of these leaves. The goal is to find out whether plant volatiles are responsible for the selection preference of O. steppensis for five species of elm. 【Methods】Air was used as a blank control odor source, and the behavioral responses of air-U. pumila, air-U. pumila L. cv. 'Tenue', air-U. davidiana ‘Changzhi’, air-U. densa, and air-U. laciniata were determined using a four-armed olfactometer. On this basis, the behavioral responses of O. steppensis to the above selected elm leaves were determined using a four-armed olfactometer, and the number of males and females arriving at the odor source vials and the time of arrival were recorded to compare the selective preferences of O. steppensis for the leaves of the five species of elm. The volatile components of the five species of elm leaves were detected by solid-phase microextraction combined with gas chromatography-mass spectrometry.【Results】O. steppensis showed no selective behavior for U. laciniata and chose the remaining four elm species, but there was a selective preference, preferring U. pumila, followed by U. pumila L. cv. 'Tenue', then U. densa, and finally U. davidiana. The number of choices made by females for U. pumila, U. pumila L. cv. 'Tenue', and U. densa were all highly significantly higher than those made by males, while there was no significant difference between the number of choices made by male and female adults for U. davidiana. In terms of reaction time, O. steppensis females took the longest time to reach U. davidiana, which was significantly higher than those of U. densa, U. pumila, and U. pumila L. cv. 'Tenue', while males took longer time to reach U. davidiana and U. densa, which was significantly higher than that of U. pumila and U. pumila L. cv. 'Tenue'. The results of the GC-MS analyses showed that a total of 79 compounds were identified from five elm leaf volatiles, and 20, 18, 31, 23 and 10 compounds were detected respectively in U. pumila, U. pumila L. cv. 'Tenue', U. davidiana, U. densa, and U. laciniata leaf volatiles. 【Conclusion】Elm leaf volatiles are responsible for O. steppensis feeding preferences on five species of elm.

摘要：

【目的】研究八斑榆跳象Orchestes steppensis成虫对白榆、垂枝榆、圆冠榆、长枝榆和裂叶榆5种榆树叶片的选择行为反应,并检测5种榆树叶片的挥发物成分,分析植物挥发物是否是造成八斑榆跳象对5种榆树取食偏好的原因。【方法】以空气作为空白对照的气味源,使用四臂嗅觉仪测定空气-白榆、空气-垂枝榆、空气-长枝榆、空气-圆冠榆和空气-裂叶榆的行为反应,使用四臂嗅觉仪测定八斑榆跳象对以上有选择的榆树叶片的行为反应,记录到达味源瓶的雌雄数量和时间,比较八斑榆跳象对5种榆树叶片的选择偏好,用固相微萃取法结合气相色谱-质谱联用仪(GC-MS)检测该5种榆树叶片挥发物成分。【结果】八斑榆跳象对裂叶榆无选择行为,选择其余4种榆树,但存在选择偏好,首选白榆、其次为垂枝榆、再次为圆冠榆、最后为长枝榆。雌虫对白榆、垂枝榆、圆冠榆的选择数量均极显著高于雄性,而雌雄成虫对长枝榆的选择数量没有显著性差异。在反应时间上,八斑榆跳象雌虫到达长枝榆所需的时间最长,显著高于圆冠榆、白榆和垂枝榆;而雄虫到达长枝榆和圆冠榆所需的时间较长,显著高于白榆和垂枝榆。从5种榆树叶片挥发物中共鉴定出79种化合物,在白榆、垂枝榆、长枝榆、圆冠榆和裂叶榆叶片挥发物中分别检测出20、18、31、23和10种化合物。【结论】榆叶挥发物是造成八斑榆跳象对5种榆树取食偏好的原因。
