Abstract

This study was conducted to identify pest occurrence patterns at the Korea National Arboretum. From May to October 2024, field surveys were conducted in the Daylily Garden, Medicinal Plant Garden, and Ornamental Tree Garden selected for their vegetation characteristics. The diversity of pests occurring on plant species in each garden was compared. As a result, 39 pest species belonging to 28 families in seven orders affected 14 plant taxa across nine families. Among these pest taxa, two insect orders, Lepidoptera (13 families, 17 genera, 17 species) and Hemiptera (8 families, 13 genera, 15 species) were the most dominant. Among all surveyed host plant species, Ligustrum obtusifolium was found to host the largest number, with 12 pest species. Leaf-feeding pests were the most common, accounting for 35 species. In terms of pest composition by garden, 17 species were found in the Daylily Garden, 16 species in the Medicinal Plant Garden, and 18 species in the Ornamental Tree Garden. To analyze species composition and structural differences in pest communities among the gardens, the Shannon diversity index was calculated. Based on the survey, a list of insect pests occurring on plant species in the surveyed gardens of the Korea National Arboretum was compiled. Among these, Naxa seriaria (Lepidoptera: Geometridae), Tetranychus kanzawai (Trombidiformes: Tetranychidae), and Pryeria sinica (Lepidoptera: Phaudidae) were identified as key pest species due to the severity of their damage. These results highlight the importance of continuous monitoring and analysis of pest occurrence patterns to develop effective and proactive pest management strategies.
