通过测定不同桉树品系叶片和叶柄的结构特征，及植株受桉树枝瘿姬小蜂危害后，叶片、叶柄结构的变化，了解不同桉树品系植株叶片、叶柄的含水率、容重、蜡质、厚度等结构特征与抗虫性的关系。结果表明：①桉树抗虫性与植株叶片的含水率呈负相关，与容重呈正相关；桉树抗虫性与叶柄的含水率、厚度和蜡质含量呈正相关，与容重呈负相关。②桉树受害后，受害叶片的含水率下降、容重增大，受害处叶柄极显著膨大，其中：中感品系受害叶柄的蜡质含量极显著减少，叶片的蜡质含量降低；高感品系未受害与受害叶片的蜡质含量差异极显著，巨圆桉（E.urophylla×E.camaldulensis）DH 201-2的叶柄蜡质含量表现出显著减少。

The structure characteristics of leaves and petioles of different Eucalyptus spp. and the change of damage and undamaged plants by Leptocybe invasa had determined. The results showed that:①There are negative correlation between insect resistance and leaf water content, and positive correlation between insect resistance and leaf bulk density. The insect resistance has positively correlated with moisture content, thickness and wax content of petioles, but negatively correlated with bulk density.②After affected by the wasp, the water content of leaves had declined and the bulk density had increased and the damaged petioles had significantly enlarged. In damaged mid-resistance varieties, petioles’ wax content had obviously decreased, but had slightly decreased in leaves. The high susceptible varieties had significant differences of wax content in leaves between damaged and undamaged plant. The results also had revealed that the wax content of petioles in high susceptible varieties, E. urophylla× E. tereticornis DH201-2 had decreased obviously.
