桉树枝瘿姬小蜂(Leptocybe invasa Fisher& La Salle)，是2000年新发现的一种专一危害桉属植物的害虫。本文从生态学的角度，于2011年7月对3种不同品(系)遭受桉树枝瘿姬小蜂危害的桉树按照全株取样法进行系统调查观测，以期为桉树枝瘿姬小蜂的防治提供指导。研究结果表明，虫瘿数量和羽化孔数量主要分布在树冠枝条的上层以及中层。3种不同品(系)桉树上危害、形成虫瘿的位置存在一定的差异。尾巨桉(广林9号)上桉树枝瘿姬小蜂主要在枝条上形成危害、出现虫瘿。窿缘桉与尾赤桉(湛201)上主要在叶柄以及枝条上形成危害、出现虫瘿。同时，对遭受桉树枝瘿姬小蜂危害的尾巨桉(广林9号)桉树进行系统调查，并计算桉树枝瘿姬小蜂虫瘿分布型。结果表明，桉树枝瘿姬小蜂虫瘿在尾巨桉(广林9号)的叶片以及枝条上均成聚集型分布，尾巨桉(广林9号)树干和侧枝上的桉树枝瘿姬小蜂虫瘿分布更为密集。

The blue gum chalcid, Leptocybe invasa Fisher & La Salle, recently invaded into China as a new quarantine pest. It was found to specifically damage Eucalyptus. The research from the view of ecology and in order to provide accurate guidance for Fisher & La Salle , the whole plants which were damaged by the blue gum chalcid were surveyed in three varieties of Eucalyptus species during July 2012. The research showed that the galls and the holes of eclosion of the pests mainly concentrated on the top of the plants, but the number of galls varies on different sites in different varieties of Eucalyptus species, for E.grandis× E.urophylla(GL-9) type the pests mainly damaged the branches, for E.urophylla× E.camadulensi (Zhan-201)and E.emserta pests mainly damaged the petioles and branches.Surveyed the E. grandis × E. urophylla (GL-9) which were damged by the blue gum chalcid in Danzhou,Hainan during July 2012. calculated the blue gum chalcid's galls distribution type. The study showed that the blue gum chalcid's galls in leaves and branches all had an aggregated distribution and the blue gum chalcid's galls in branches were more closely distributed than leaves.
