为掌握广东省重要景观树种病虫害种类及发生情况，为景观林病虫害的防治和景观林带树种配置提供依据。2011—2014年，通过普查和设置样地调查，对广东省37种常用景观树木的病虫发生种类及为害严重性进行了研究。结果表明，对植物造成危害的害虫92种，病害22种，其中食叶害虫57种，刺吸式害虫23种，钻蛀害虫7种，地下害虫5种。根据病虫发生量和危害程度，对病虫害划分为4个等级，其中凤凰木夜蛾（Pericyma cruegri）、双线盗毒蛾（Porthesia scintillans）、广州小斑螟（Oligochroa cantonella）等22种害虫易暴发成灾，对景观树木产生严重为害，需进一步开展生物学特性及防治措施研究。

This paper mainly presented the research on the species and the seriousness of the diseases and pets about 37 species landscape trees in Guangdong Province through the general investigation and the setting sample plot survey in 2011-2014.The research which was to grasp the species and occurrence of diseases and pests on important landscape trees in Guangdong Province, and provide a basis for the landscape configuration and pests and diseases prevention. The results showed that 92 species of insect pests and 22 species of diseases caused harm to the trees,including 57 species of defoliating insects,23 species of sucking insects,7 species of trunk-boring insects and 5 species of underground insects.Based on the seriousness, the pests and diseases were graded 4 levels, and 22 pests showed a potential outbreak to their hosts, includingPericyma cruegri,porthesia scintillans,Oligochroa cantonellaetc. It is necessary to do some researches on their biological characteristics and prevention measures.
