Abstract

Abstract:

Leptocybe invasa Fisher et LaSalle, an invasive gall-making wasp on trees of Eucalyptus spp., was newly found in Guangxi, China. In this paper its morphological characters were described. The pest formed galls on the twigs, midribs and leaf petioles of the host trees. Those caused deformation of twigs and leaves. It severely weakened and eventually stunted the growth of host tree. Currently the infestation rate in the Eucalyptus stands reached up to 100%, therefore, the pest would potentially threaten Eucalyptus plantations in South China.

Key words: invasive forest pest, Leptocybe invasa, Eucalyptus, China
