In Sept. 2024, an investigation was conducted on the occurrence types, distribution range, and damage conditions of forest pests in the Fujian section of Wuyishan National Park. Based on the field investigation results, a risk analysis of the main pests was carried out. Through on-site investigation, 135 species of forestry pests were discovered, including 46 families in the order Lepidoptera, Hemiptera, Coleoptera, Orthoptera, Isotera and Hymenoptera. Among them, Lepidoptera pests were the most numerous, followed by Hemiptera pests. Based on the results of this field investigation and light trapping, combined with the third national forest pest and disease census, the census of invasive alien species in the forest, grassland and wetland ecosystems of Wuyishan National Park, and the literature records, a risk assessment was conducted for four highly damaging pests: Monochamus alternatus, Anoplophora glabripennis, Hylobitelus xiao, and Dendrolimus punctatus. The results showed that D. punctatus posed a high risk, while the other three species were classified as medium risk. This field investigation has basically clarified the types of forestry pests in the Fujian section of Wuyishan National Park and conducted risk assessments on the main forestry pests, providing a theoretical reference basis for the prevention of the occurrence and spread of forestry pests in this area.
