摘要
为了解苏州市姑苏区园林绿化植物的病虫害发生及其为害情况,研究于2024年采用重点调查与踏查相结合的方式,使用诱虫灯等监测设备,对该区域主要风景区、公园和绿地等地的常见病虫害发生种类和为害程度等进行调查分析。结果表明,研究区园林绿化植物主要病害有28种,为害严重的有海棠褐斑病、紫荆角斑病、悬铃木白粉病等;主要害虫有68种,为害严重的有黄杨绢野螟、重阳木锦斑蛾、银杏超小卷蛾等15种。研究区病虫害发生情况总体表现为日灼病重度发生,白粉病、锈病等偏重发生,炭疽病、叶斑病、煤污病等中度发生;蛀干害虫偏重发生,食叶性害虫重阳木锦斑蛾等前期中度发生,刺吸式害虫悬铃木方翅网蝽等中度偏重发生。基于此,提出病虫害防治措施包括提升植物养护和病虫害防治水平,加强病虫害监测和植物检疫等工作,利用物理防控、生物防治等综合防控方式。
To understand the occurrence and damage caused by diseases and pests in landscape plants in the Gusu District of Suzhou City,an investigation was conducted in 2024 using a combination of key surveys and transect surveys,and monitoring equipment such as insect traps.The study focused on common types of diseases and pests and the extent of damage in major scenic areas,parks,and green spaces within the region.The results indicated that 28 major diseases were identified on landscape plants in the study area,with severe cases notably including hawthorn leaf blight,redbud angular leaf spot,and plane tree powdery mildew.Additionally,68 major pest species were identified,with 15 causing significant damage,such as Diaphania perspectalis,Histia rhodope,and Pammene ginkgoicola.Overall,the occurrence of diseases and pests in the study area was characterized by severe sunscald,relatively heavy occurrences of powdery mildew and rust,and moderate occurrences of anthracnose,leaf spot,and sooty mold.Among pests,borers were relatively prevalent,while leaf-eating pests such as Histia rhodope were moderately common in the early stages,and sap-sucking pests like the sycamore lace bug were moderately to heavily prevalent.Based on these findings,control measures were proposed to include improving plant maintenance and pest management,enhancing monitoring and plant quarantine efforts,and adopting integrated management strategies such as physical and biological control methods.
