Wood boring insects are pests that burrow into the interior of trees, causing significant damage and posing serious threats to forest ecosystems and urban landscapes. Especially in Korea, the native species Aromia bungii causes severe damage to Prunus × yedoensis trees, posing significant problems. The damage caused by A.bungii can be identified externally through signs such as emergence and entrance holes on tree stems with sawdust like frass on grounds, but accurately assessing the extent of internal damage requires cutting down the tree. This study uses a non-invasive sonic tomography technique to analyze the correlation between external damage characteristics and internal damage in P.× yedoensis trees affected by A.bungii. The findings show significant difference in internal damage rates of infested trees compared to undamaged trees, although some undamaged trees exhibited injuries caused by abiotic factors and wood-decay fungi. The results demonstrate that sonic tomography is an effective tool for non-invasive assessment of internal damage caused by wood-boring insects, offering a practical alternative to more destructive methods.
