The interference effect of volatile oil from whitefly (Syngonium podophyllum) on aptera aphid, guard aphid (Aphis gossypii), mustard aphid (Lipaphis erysimi) and red peach aphid (Myzus persicae) was studied by using four arms olfraetometes. The results showed that the volatile oil had distinct repelling effect. The staying periods of test aphids in test areas were obviously shorter than in control areas, and the selecting frequencies were less than the control, too. The volatile oil did not show repelling effect on red peach aphid at the test concentrations. The components of the volatile oil from S. podophyllum were analysed by GC-MS. 43 constituents were identified.
采用四臂嗅觉仪研究了合果芋挥发油对无翅蚜、棉蚜、菜缢管蚜和桃蚜的干扰作用。结果表明，该挥发油具有明显的驱避作用。供试蚜虫在试验区的停留时间明显短于对照区，选择频率也低于对照。在试验浓度下，该挥发油对桃蚜未表现出驱避作用。采用气相色谱-质谱联用仪分析了合果芋挥发油的成分，共鉴定出43种成分。
