Abstract

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 spp. It was reported in Mediterranean countries, northern and eastern Africa, Middle East and southeast Asia in the past few years. It was found in mainland China Guangxi Province in 2007. In July 2008, the blue gum chalcid was discovered in Hainan Province. Through investigating around the Hainan Island, we found that L. invasa has been outbreak in tow circularity shape zone, which was around Sanya, Dongfang and Danzhou city. Heavy galling causes the leaves to warp and stunt the growth of the tree. The paper records its occurrence and spreading in Hainan, provided with morphological characters, biology and quarantine advice.
