摘要： 以TN1为供试水稻品种，研究了稻株挥发物在褐飞虱、白背飞虱寻找寄主及调节两种飞虱种内种间关系中的作用。结果表明健康稻株挥发物对褐飞虱、白背飞虱具有明显的引诱作用。当稻株被一种飞虱为害12 h后，其所释放的挥发物对另一种飞虱有明显的引诱作用，但对同种飞虱则无显著的吸引或驱避作用。随着为害程度的加重（为害1 d以上），两种飞虱均避开虫害株而趋向健康稻株。

Abstract: Mediations of volatiles on host plant selection by brown planthopper (BPH) and whitebacked planthopper (WBPH), and on intra and inter specific relationships of BPH and WBPH were studied using rice variety TN1. Results showed that volatiles of health rice attracted BPH and WBPH apparently. Volatiles emitted from rice sucked by one planthopper species for 12 h, attracted the other planthopper species, but it had no significant effect (attraction and deterrent) on conspecific planthopper. Both of the two species of planthoppers avoided sucked rice and preferred to health rice when the damage became seriously.
