5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Manuscript is well written with new information but the manuscript miss the detailed study.

1. Rearing of Helopeltis in cocoa pods has to be tried

2. Screening of cocoa pods and shoots has to be conducted with three species of Helopeltis

3. Cocoa pod screening has to be condcuted directly in field to understand the feeding preference

4. Choice test has to be conducted

5. Helopeltis can easily adapt to resistant clones in matter of time

6. All the comments are directly marked in the MS

7. Study has to conducted with above points to get the real answer of resistant clones

Reviewer #2: Dear Authors

The work done on screening 20 varieties of cocoa against TMB based on the phenolic activity is appreciated. The findings in this study will definitely help researchers in plant improvement work in future. The manuscript structure is good but author has to be little bit focussed and concentrated while preparing manuscript. Some points for improvement are listed here:

1. Line 80- the normal reference style is deviated

2. A scoring method to classify the varieties as highly resistant to highly susceptible and reference quoted as no. 8. I had gone through the original paper of Srikumar and Bhatt but couldn’t find any mention on scoring there. They describe life table studies (line 80,151)

3. In many places in manuscript, author made non sensible reference citation ( line 70,90, 135, 137, 189) It is suggested to go through different papers published in PloS One journal for understanding the correct citation of references in text.

4. Line 101 and 102-repetition

5. It is good if you can add author name to the scientific name when mentioned first time in text ( line 130 for Mikania micrantha)

6. Line 131- females started laying eggs in two days… whether they were collected from field or from insectary?

7. In Line 87 Fig 2 is mentioned which is quite irrelevant

8. Results portion may be modified and thoroughly checked as some mismatching were found. Line 151- author says 5 hybrids were ranked as Highly resistant where as table shows there were seven. Listing of varieties based on your observations in text should not be confusing to the readers. Please make it in order as they appear or in ascending /descending order of resistant.

9. A strong negative correlation is not observed especially in case of pods

10. Please pay more attention and ethics while preparing manuscript in future

**********

Revision 1

Comment 1. Rearing of Helopeltis in cocoa pods has to be tried

Response: We tried rearing Helopeltis in cocoa pods and the result was a failure. We are rearing Helopeltis in insect rearing cages for that detached pods were used, these pods start to decay within 4 to 5 days which makes it difficult to rear Helopeltis on cocoa pods.

Comment 2. Screening of cocoa pods and shoots has to be conducted with three species of Helopeltis

Respone: In the cocoa farm of Kerala Agricultural University we have identified only Helopeltis theivora attacking cocoa. Even though the adjacent farm is of cashew there we can see all the three species of tea mosquito bug, other two species are not preferring cocoa over cashew. Once we collected all the three species and tried to feed cocoa by enclosing them in insect rearing cages. However, only Helopeltis theivora survived.

Comment 3. Cocoa pod screening has to be conducted directly in field to understand the feeding preference

Respone: We conducted field screening during the peak season of attack for consecutive three years and found that the result is on par with the present study.

Comment 4. Choice test has to be conducted

Respone: Budded plants were screened by following choice test. However, it is difficult to collect pods of similar maturity from all the twenty hybrids at a time force test was followed for screening pods.

Comment 5. Helopeltis can easily adapt to resistant clones in matter of time

Respone: Clones with diverse genetic origin is included in the study and all the resistant clones will be used as parents in the establishment of polyclonal garden

Comment 6. All the comments are directly marked in the MS

Respone: Thank you for the effort, we considered all those comments to improve our article

Comment 7. Study has to conducted with above points to get the real answer of resistant clones

Respone: Apart from polyphenol content in case of seedlings colour of the tender flush leaves was also studied and we tried to correlate that with TMB incidence. Unfortunately, we were not able to get a strong correlation. Similarly for pods we also tried to correlate pod shape, unripe pod colour, pod apex and base form and pod rugosity with TMB attack, however none of these characters showed a significant correlation

Reviewer #2: Dear Authors

The work done on screening 20 varieties of cocoa against TMB based on the phenolic activity is appreciated. The findings in this study will definitely help researchers in plant improvement work in future. The manuscript structure is good but author has to be little bit focussed and concentrated while preparing manuscript. Some points for improvement are listed here:

Comment 1. Line 80- the normal reference style is deviated

Respone: The reference styles are now made consistent.

Comment 2. A scoring method to classify the varieties as highly resistant to highly susceptible and reference quoted as no. 8. I had gone through the original paper of Srikumar and Bhatt but couldn’t find any mention on scoring there. They describe life table studies (line 80,151)

Respone: We referred the research article of Srikumar and Bhatt and discussed with the authors to construct a scoring table which suits our study.

Comment 3. In many places in manuscript, author made non sensible reference citation ( line 70,90, 135, 137, 189) It is suggested to go through different papers published in PloS One journal for understanding the correct citation of references in text.

Respone: Sorry for the mistake from our part, references are now made consistent with PloS One format

Comment 4. Line 101 and 102-repetition

Respone: We removed the repeated line from the manuscript

Comment 5. It is good if you can add author name to the scientific name when mentioned first time in text ( line 130 for Mikania micrantha)

Respone: We made it correct in the manuscript by adding authors name

Comment 6. Line 131- females started laying eggs in two days… whether they were collected from field or from insectary?

Respone: Adult males and females were collected from field and allowed to mate and lay eggs

Comment 7. In Line 87 Fig 2 is mentioned which is quite irrelevant

Respone: We removed it from the manuscript

Comment 8. Results portion may be modified and thoroughly checked as some mismatching were found. Line 151- author says 5 hybrids were ranked as Highly resistant where as table shows there were seven. Listing of varieties based on your observations in text should not be confusing to the readers. Please make it in order as they appear or in ascending /descending order of resistant.

Respone: Sorry for the inconvenience, we modified the result portion and the table in the manuscript.

Comment 9. A strong negative correlation is not observed especially in case of pods

Respone: A moderate negative correlation was observed in case of pod. Necessary corrections are made in the manuscript.

Comment 10. Please pay more attention and ethics while preparing manuscript in future

Respone: We sincerely appreciate all valuable comments which helped used to improve our article. We have revised the article as per the suggestion of reviewers. Surely, we will pay more attention while writing the article in the future.

Reviewer #2: Happy to know that almost all the suggestions which I pointed out were taken seriously by the authors and found incorporated in the revised manuscript. But still some points have to be addressed before accepting the same for publishing. The points are mentioned below:

1. Scoring method on screening is still not conspicuous. Not satisfied with the explanation by the authors. Reference mentioned in line 87 doesn’t pertain to the subject (scoring). Authors replied that they discussed with the authors of reference cited (as ref. no. 8) and derived a method. Developing a reliable scoring method is fine but citing an irrelevant reference is not a good practice.

2. What is the transformation used for data in table 3? It is not mentioned in table or text.

3. Reference 16 is not in journal format. please refer https://journals.plos.org/plosone/s/submission-guidelines for assistance

4. Year of publication and page no. are missing from reference no. 2. The correct year is 2017 and page no.199-213.
