Abstract: In this study, the taxis of Asian citrus psylla, Diaphorina citri, to volatile oils extracted from its five non-host plant species and a petroleum spray oil were tested by using a four-armed olfactometer. The result showed that the volatile oils from the plant species, Mikania micrantha,Lantana camera, Eupatorium catarium and Wedelia chinensis had significant repellency effect on adult of Asian citrus psylla. Among them, the effect of volatile oil from M. micrantha was the strongest, while there were not repellency or attractive effect for the eucalyptus oil and petroleum spray oils to the pest. There was not any difference between the females and males taxis to these oils. The result demonstrated that the repellency of volatile oils from the non-host plants against Asian citrus psylla was very sngnificant. It could be possible to use these oils in integrated management of the pest.
