AbstractTo 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 2O24 using acombination of keysurveys and transect surveys， and monitoring equipment such as insect traps.The study focused on common types of diseases and pests and he extent of damage in major scenic areas，parks，and green spaces within the region.The results indicated that28 major diseases were identified onlandscape 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， with15 causing significant damage，such asDiaphania perspectalis，Histiarhodope，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 inthe early stages，and sap-sucking pests like the sycamore lacebug were moderatelyto heavily prevalent.Basedon these findings，control measures were proposed to include improving plant maintenance and pest management，enhancing monitoring and plant quarantine eforts，and adopting integrated management strategies suchasphysicaland biological control methods.
