Reviewer 2 Report (Previous Reviewer 2)
Comments and Suggestions for AuthorsDear authors,
Although you claim that your paper was revised for language mistakes, I still see many of them in it. This means that a specialist in Scientific English should revise your manuscript.
Below are my remarks :
Line 109: place 'in' between measured and all.
For the rest of your text : there are many other mistakes related to the tenses, etc.
Lines 116- 120: suppress these sentences (the information was already presented, or will be explained in the following sentences highlighted in yellow).
Figure 1 :for photos other than a and e, manage to indicate to which species there are related.
Line 143 : The sentence: "SoT was different in tree by tree" is not understandable.
Line 304 : photo e is missing.
Line 311: photo d is missing
In conclusions: you should briefly indicate the limitation of your system, as well, as it is not really efficient for trees with early infestations.
Line 522 : Cadophora margaritata should be put in italics.

Reviewer 3 Report (New Reviewer)
Comments and Suggestions for AuthorsTitle: Application of non‒invasive sonic tomography to evaluate internal status of urbans trees infested by two cerambycid beetles, Aromia bungii and Massius raddei
Author: Lee et. Al.
This article describes the use of sonic tomography to identify the level of damage caused by beetles. The article is written in a clear manner and has potential practical value.
The current title suggests that in addition to non-invasive, there is also invasive sonic tomography. Perhaps it would be better in this way:
Non‒invasive assessment of the internal condition of Urbans trees infested by two cerambycid beetles, Aromia bungii and Massius raddei, using sonic tomography
Use passiv and not active
Figure 1 – From the cross-section of the image, it can be seen that the actual cross-section of the tree and the tomography are not taken at the same position. Can you show the cross section and tomography at the same position? Enlarge the legend too! Also add a description for the green colour!
L180-182 “Principal component analysis (PCA) was performed to explore the relationships among the variables acquired from visual investigation, sonic tomography, and tree characteristics” – which tree characteristics?
Figure 3. – the Figure is not clear enough! What does x axis represent? No. of holls – Low, moderate??
L277-278 “When single gallery was found in cross-section, injured areas were represented by green color on the tomograms as their sound velocity was faster compared to that of healthy areas.” – How can the speed of sound be faster in injured areas compared to healthy areas?

- Response: Thank you for the valuable comment. We revised the title as reviewer’s suggestion.
- Figure 1 – From the cross-section of the image, it can be seen that the actual cross-section of the tree and the tomography are not taken at the same position. Can you show the cross section and tomography at the same position? Enlarge the legend too! Also add a description for the green colour!
- Response: Thank you for the comment. Are you means ‘Figure 5’ instead of ‘Figure 1’? If it is, cross-section images and tomography were taken at the similar position as possible. In our opinion, sensor position may be a reason for the difference. However, we changed the figure, especially for Prunus trees and its ST. These figures, ST and actual cross-sectional photograph, acquired in this year and we replaced the Figure 5a and 5b in original version ms. Because of important changes in Figure 5, we additionally described details in Materials and Methods. And figure legend was also changed you suggested.
- L180-182 “Principal component analysis (PCA) was performed to explore the relationships among the variables acquired from visual investigation, sonic tomography, and tree characteristics” – which tree characteristics?
- Response: Thank you for the comment. We added details about tree characteristics.
- Figure 3. – the Figure is not clear enough! What does x axis represent? No. of holls – Low, moderate??
- Response: Thank you for the comment. We changed the figure clearly and revised the figure caption in version ms.
- L277-278 “When single gallery was found in cross-section, injured areas were represented by green color on the tomograms as their sound velocity was faster compared to that of healthy areas.” – How can the speed of sound be faster in injured areas compared to healthy areas?
- Response: Thank you for pointing out this error. In our expression in the sentence, ‘injured areas’ means ‘single gallery’. We revised this sentence to understandable.
This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe study aimed to explore the internal damage status of roadside trees, specifically P. × yedoensis infested with A. bungii and Quercus palustris infested with M. raddei in urban landscapes using non-invasive SoT imaging. Additionally, the study aimed to analyze the correlation between external evidence of infestation (including wounds and adult emergence holes caused by cerambycid beetles) and the extent of interior damage based on SoT.
96 trees were investigated. Each tree was visually examined for external signs of infestation by cerambycid beetles. Each tree was counted for the number of entrance‒ and emergence‒holes caused by larvae and adults, respectively, from the base up to a height of 1.5 m.
By converting the results of visual investigation into natural logarithms, damage levels were classified incrementally by 1, such as 0 ~ 1.0, 1.1 ~ 2.0, 2.1 ~ 3.0, and 3.1 ~ 4.0. The results of entrance and emergency holes caused by larvae and adults are not shown in the paper. It is also not known how many holes determined the level of damage. According to the authors, this is shown in Figure 2. Figure 2 shows the correlation between the level of damage assessed by the tomograph and the natural logarithm. The correlation is positive. Such a result can be predicted without the use of testing tools. A more valuable result is the correlation between the level of damage and the number of holes.
However, I consider such an analysis to be flawed, since the number of holes was obtained from a 1.5 m section of the trunk. On the other hand, the level of damage can only be assessed on the cross-section of the trunk based on the CT scan. This is the first serious comment on the research method. The second is to show the results of the level of damage, which is not because of the presence of insects. Rot severely distorts the test results, as was shown by the authors. This can lead to incorrect conclusions.
I also cannot positively assess the discussion and the conclusion. This mainly concerns cracks that were not the target of the analyses. Cracks cannot be correlated with the number of holes. Cracks can affect the dynamics of rot development. However, this was not the purpose of the work.
The study evaluated trees growing in urban conditions. Thus, the results should provide information important for urban tree management. Mainly in terms of safety around trees. The presence of xylophages can affect tree statics, but it is unknown what level of damage would be critical. Simply stating that the level of damage depends on the number of holes is insufficient evidence to verify the research hypothesis. Especially since it is impossible to separate insect damage from rot damage.
I appreciate the authors for their contribution to the work. However, in my opinion, the results cannot be published.

English should be revised. some sentences are not well formulated, thus not giving the true meaning, others are full of mistakes (verb tenses, etc).
