Abstract: 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.

Key words: Syngonium podophyllum, Volatile oil, Lipaphis erysimi, Myzus persicae, Aphis gossypii
