摘要: 鉴定北艾(Artemisia vulgaris L.)和辽东蒿(Artemisia verbenacea (Komar.) Kitagawa)对蚜虫的趋避和毒杀效果,并对其挥发物成分进行分析,旨在挖掘菊花近缘种属抗蚜性种质。本研究通过Y型嗅觉仪行为趋向测试和室内蚜虫接种鉴定试验检测北艾、辽东蒿对菊姬长管蚜的抗性,并利用有机提取和GCMS对其挥发物成分进行鉴定分析。结果表明:北艾和辽东蒿的挥发物对菊姬长管蚜表现出强烈的驱避性;室内蚜虫接种鉴定试验表明北艾和辽东蒿对菊姬长管蚜的繁殖均具有明显的抑制作用;GCMS分析发现,不同植物部位挥发物成分差异明显,叶中的特有成分明显多于茎和根,大多数共有成分在叶片中的含量较高;北艾和辽东蒿的叶和茎中存在桉树脑、叶绿醇、β-可巴烯、香豆素等抗虫成分,根中的主要成分是(Z)-3,7-二甲基-2,6-亚辛基-1-醇丙酸酯;北艾、辽东蒿对蚜虫具有明显的趋避和毒杀效果,且其叶和茎中含有大量抗虫挥发物成分,为抗蚜性种质。

Abstract: The effects of Artemisia vulgaris and A. verbenacea on aphid repellency and resistance, and the components of volatiles were analyzed to discover the aphidresistant plants. We used Y-tube olfactometer behavioral trend test and indoor aphid infestation to identify the resistance of A. vulgaris and A. verbenaceato aphid. The volatile organic components were extracted via organic extraction and identified by GC-MS. Results from the Y-tube olfactometer behavior analysis showed that A. vulgaris and A. verbenacea are repellent to aphids.A. vulgaris and A. verbenaceahave an obvious inhibitory effect on the aphid population. The volatile components in the leaves, stems and roots of A. vulgaris andA. verbenacea were significantly different. The number of unique components in the leaves was significantly higher than that in the stems and roots. Furthermore, the concentrations of major common components in the leaves were higher. Eucalyptol, phytol, β-copaene and coumarin in the leaves and stems are toxic to insects. The neryl propionate is the major VOC in the roots. A. vulgaris and A. verbenacea have obvious effects on aphid repellency and resistance, and their leaves and stems contain many insect-resistant volatile components. Both species are aphid-resistant germplasms.
