Rice secondary volatiles were extracted from a planthopper resistant variety, IR36, and a susceptible variety, TN1, and the effects of extracted volatiles on the orientation，growth and EAG response of Nilaparvata lugens(Stl), BPH adults were tested (Homoptera: Delphacidae). Volatiles extracted from TN1 had a positive effect on feeding and growth of Nilaparvata lugens, and they have attraction functuion on the insects, too. In contrast，volatiles from resistant variety IR36 had opposite effects on BPH mortality and growing. The EAG results showed that the response to TN1 volatiles was stronger than to IR36 volatiles, and that responses were positively related to volatile concentration. EAG responses of short\|wing BPH were stronger than those of long\|wing BPH, and male BPH was more responsive than female BPH adults. GC\|MS analysis of rice secondary volatiles showed chemical large discrepancy in composition between resistant variety IR36 and susceptible variety TN1. There were a total of 44 volatile compounds identified from rice leaves, some of them attractants for Nilaparvata lugens.
