| 摘要: |
| 2011-2014年,结合谱查和设置样地调查,对广东省37种常用景观树种进行连续调查,研究不同树种的病虫发生种类及为害严重性。结果表明,共发现对植物造成危害的虫害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,对发生的病虫进行为害划分为4个等级。其中凤凰木夜蛾、双线盗毒蛾、广州小斑螟等22种害虫易暴发成灾,对景观产生严重为害,需进一步开展生物学特性及防治措施研究。结果对景观林病虫害的预防和景观林带树种配置具有一定指导意义。 |

| Abstract: |
| In 2011-2014, 37 landscape species were investigated consecutively on the diseases and pests by setting fixed plots and constructed landscape belts, to find out the disease and pest species and seriousness to the trees. The results showed that 92 species of insect pests and 22 species of disease caused harm to plants,including 57 species of defoliating insects,23 species of sucking insects,7 species of trunk-boring insects and 5 species of underground insect．According to the seriousness, the pests and diseases were graded 4 levels, and 22 pests showed a potential outbreak to their hosts, including Pericyma cruegri (Butler), porthesia scintillans (Walker),Oligochroa cantonella etc. It is necessary to do some research on their biological characteristics and prevention measures. The results have a significant meaning on landscape configuration and the prevention of pests and diseases. |
