Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The MS provides some new information to evaluate the potential of the  two predatory mites. I think it should be accepted after a major revision.  The points I concern:

1. Abstract: the data of the two mites with three diets were not clearly expressed, which mite had which developmental time, oviposition period, survival, ...?

2. Table 1-3: the abc letters to indicate the significanse should be compared in a same column, but not in whole table. Also, I prefer to combine the table 1 and 2 together.

3. Table 3: what the difference in Total fecundity± SD and Average of eggs± SD, Daily fecundity and Daily egg-laying rate ?

4. Table 5/6: the "Total" in column "Predatory stage" , this line is not necesary.  I think some tables can be changed as to graphies, maybe improve the merit of the MS.

5. References: too many, I think at least 20 documents are able to delet, such as 9/23/25/45-48/50-52/60-62/68-70/73, etc., these are so old or little relevance.

Others I concern were labelled in pdf file attached.

Reviewer 1

Comment 1- Abstract: the data of the two mites with three diets were not clearly expressed, which mite had which developmental time, oviposition period, survival, ...?

Author response: Thank you for pointing this out. The reviewer is correct, and the abstract has been rewritten.

Comment 2- Table 1-3: the abc letters to indicate the significance should be compared in a same column, but not in whole table. Also, I prefer to combine the table 1 and 2 together.

Author response: The different letter denotes significant difference within species in a same column on all three diets tested. Also, Tables 1 and 2 contain a lot of data, making it challenging to combine them.

Comment 3- Table 4: what the difference in Total fecundity± SD and Average of eggs± SD, Daily fecundity and Daily egg-laying rate ?

Author response: This was a table error, and it has been corrected

Comment 4- Table 5/6: the "Total" in column "Predatory stage", this line is not necesary.  I think some tables can be changed as to graphies, maybe improve the merit of the MS.

Author response: Total" in column "Predatory stage" has been removed

Comment 5- References: too many, I think at least 20 documents are able to delet, such as 9/23/25/45-48/50-52/60-62/68-70/73, etc., these are so old or little relevance.

Author response: References have been deleted.

Reviewer 2 Report

Comments and Suggestions for Authors

COMMENTS TO MANUSCRIPT Plants-3077516 “Potential of two phytoseiid mites as predators of the grape eri-neum mite, Colomerus vitis”

 

The manuscript deals with an interesting subject, as it is the better knowledge of potential arthropods to implement biological control of agricultural pests. Biological control of eriophyd mites is rather scarce, and research that could fill this gap is always welcome.

The authors present interesting results of the capability of two species of phytoseiids to feed and complete its developtment on a known pest of grapes, Colomerus vitis. The manuscript follow the scheme of the classical lab study where different biological parameters are studied, ending with the biotic potential of both phytoseiid species. But the presentation of the work presents important flaws. The Results are not well structured, it lacks proper information of statistics results,  and this produced confussion, at least in the reviewer. Discussion is also very extensive, and it can be reduced and presented in a more readable way.

Although the reviewer is not a native English speaker, I found the language can (and should) be improved.

 

Particular comments to the manuscript follow:

 

ABSTRACT

Lines 14-16. Include that also C. vitis alone as food source was investigated.

Lines 18-20. Rewrite this sentence, because it is not clear what species are you talking about.

Lines 24,25, 26. Include “respectively” after ech couple of figures to indicate that each number correspond with the phytoseiid species in the same order.

Line 28. Include the following: “…erineum mite and date palm pollen, although the values obtained with only erineum mite were very similar.”

 

INTRODUCTION

Line 74. It seems as “thrips” should be located before whiteflies: “…Tetranychoidea), thrips and whiteflies in orchards…”

Line 100. Although the objective of the research is clear, it lacks the study of the biotic potential of the pest/prey. Knowing this value (directly with lab studies of the authors, or with references from other studies), it would be more interesting (and with sense) the comparation with the phytoseiids biotic parameters found in the present work.

Authors do not present any reference (if there is any) about this subject, but they should make some statement about this subject in the Introduction.

RESULTS

Line 104 “ 2.1. Developmental Time and Survival of Immature Stages”. In the present state this is an unique paragraph quite unreadable. You must separate in different paragraphs with homogeneous content, which will make easier to read and understand it.

Another comment to this paragraph: Tables must be mentioned in a consecutive order. You start mention Table 1, and after you mention Table 3, where is Table 2?.

Line 114. You mention values of P (like “P<0.05, and others) for a comparation in Table 1, but there is nothing included in the Table. P values, accompanied with the F value and the degree of freedom of the statistical analysis, must appear in the tables, particularly in Tables 1 and 2.

For example, in Table 1 and Table 2 appear  a value of F and P that it is not clear to what column is related and the meaning of them (it is not explained in any part of the text).  In Tables 1 and 2 it must be clear what statisitical comparation are you doing. Are you comparing both phytoseiid species in the same analysis?. If you are comparing separately each species you must include the statistics values for each species analysis in the tables.

Line 116. Split here the paragraph.

Lines 120-123. You talk here of Table 7. Better move this comment to where Table 7 is again mentioned to explain the results of biotic parameters.

IN this lines there is not match of what you said in the first sentence (“…insignificant differences…”), with the p value presented (p=0.0210). Correct it.

 

Add at the end of sentence in line 123 “"for both phytoseiids species".

 

Lines 127 and following. Split paragraph. You start describing results of TAble 2. Mention Table 2 at the beginning to make clear what are you talking. Move this part to put it after the Table 1 content.

Lines 142-148. Start mentioning that you are talking about results of Table 4. The figures mentioned do not match with values in Table 4. Check them and correct.

Lines 150-152. This sentence correspond to TAble 2. Reorder.

 

Line 153 “2.2. Predation of P. Plumifer and E. Scutalis”. In the present state this is an unique paragraph quite unreadable. You must separate in different paragraphs with homogeneous content, which will make easier to read and understand it.

Line 159. Authors include here only a value of p (“P<0.001”). If not included in the Table, here you put clearly what comparation are making, with P, F, and d.f. values. The paragraph needs a thorough rewritting to make it understandable.

Line 163. Mention the Tables you are talking at the beginning of the paragraph.

Lines 164-165 and following. Rewrite properly. It is not well expressed, with figures without units and the standard error. This also happen in other parts of the paragraph that also must be corrected.

Lines 173-177. Rewrite to fit standards of publication in a scientific journal. In the present way is not easy to read and understand.

Lines 177-187. Too descriptive and very long. I think this can be reduced to give the idea, and refer to the Tables 5 and 6.

TAble 2. Put the units of the measures. They are days, aren’t they?

 

Line 1 (page unnumbered) 2.3. Population Growth Parameters

The values for pollen plus eriophyd are very similar to the obtained with the eriophyd alone. As there is no variability in the parameters it is not easy to say if they are really different, but the values are very close each other and the autohors should mention this.

The values with the pollen alone are clearly lower, at least compared with the pollen plus mites.

Simplify all the paragraph because it is not neccessary to mention all the values, give the general idea and refer to table 7.

Line 5. “.. palm pollen for both predators. The…”

 

Table 3. Eliminate letters if there is not significative differencies between treatments. Mention that point (no significative differences) at the foot of the table and when you explain the results.

 

Table 4. Headings are not equal for the two phytoseiids. Correct it.

Footnote: Letters in the row does not seem to fit the statement. And besides they are not put correctly. C. vitis a b  - C.vitis+pollen a b

 

TAble 5. Correct the position of figures in colum “Dayly rate”  of P. plumifer.

Footnote: Explain that the comparation is made only with females.

 

Table 6. Correct the position of figures in colum “Dayly rate”  of P. plumifer.

Footnote: Explain that the comparation is made only with females.

 

DISCUSSION

The discusiion is very extensive and prolix. The second paragraph must be split in several to gain readability. Any effort of the authors to simplify the content will make the text more readable.

As has been mentioned at the beginning, it would be interesting for previewing the possible success in biological control of the two phytoseiids to know the biotic values of the prey. If authors have information of the biotic capabilities of the prey they should mention here in extend.

 

CONCLUSSIONS

Lines 235-236. I think it is more appropiate to rewrite the sentence as:

“In conclusion, our results demonstrate that the grape erineum mite C. vitis is a suitable prey for both phytoseiids P. plumifer and E. scutalis, making them…”.

Knowing this value (directly with lab studies of the authors, or with references from other studies), it would be more interesting (and with sense) the comparation with the phytoseiids biotic parameters found in the present work. Authors do not present any reference (if there is any) about this subject, but they should make some statement about this subject in the Introduction.

Author response: This study was the first to assess the biology and predatory efficiency of the phytoseiid predators, P. plumifer and E. scutalis against C. vitis as prey.

Comment 4- Line 104 “ 2.1. Developmental Time and Survival of Immature Stages”. In the present state this is an unique paragraph quite unreadable. You must separate in different paragraphs with homogeneous content, which will make easier to read and understand it.

Author response: The paragraph has been divided and the sentence rewritten.

Comment 5- Another comment to this paragraph: Tables must be mentioned in a consecutive order. You start mention Table 1, and after you mention Table 3, where is Table 2?.

Author response: The tables have been mentioned in a consecutive order. Except for Table 7, the sex ratio is usually written with the life table parameters tables

Comment 6- Line 114. You mention values of P (like “P<0.05, and others) for a comparation in Table 1, but there is nothing included in the Table. P values, accompanied with the F value and the degree of freedom of the statistical analysis, must appear in the tables, particularly in Tables 1 and 2. For example, in Table 1 and Table 2 appear  a value of F and P that it is not clear to what column is related and the meaning of them (it is not explained in any part of the text).  In Tables 1 and 2 it must be clear what statisitical comparation are you doing. Are you comparing both phytoseiid species in the same analysis?. If you are comparing separately each species you must include the statistics values for each species analysis in the tables.

Author response: Typically, the P value is indicated in the text to denote significance. Its removal from the tables was requested by one of the reviewers.

Comment 7- Line 116. Split here the paragraph.

Author response: The paragraph has been divided

Comment 8- Lines 120-123. You talk here of Table 7. Better move this comment to where Table 7 is again mentioned to explain the results of biotic parameters.

Author response: The comment has been moved to where Table 7  is mentioned

Comment 9- IN this lines there is not match of what you said in the first sentence (“…insignificant differences…”), with the p value presented (p=0.0210). Correct it.

Author response: We have made the correction

Comment 10- Add at the end of sentence in line 123 “"for both phytoseiids species".

It is added at the end of the sentence

Comment 11- Lines 127 and following. Split paragraph. You start describing results of TAble 2. Mention Table 2 at the beginning to make clear what are you talking. Move this part to put it after the Table 1 content.

Author response: All paragraphs have been moved before the tables

Comment 12- Lines 142-148. Start mentioning that you are talking about results of Table 4. The figures mentioned do not match with values in Table 4. Check them and correct.

Author response: The sentence has been modified and the paragraphs have been separated

Comment 15- Line 159. Authors include here only a value of p (“P<0.001”). If not included in the Table, here you put clearly what comparation are making, with P, F, and d.f. values. The paragraph needs a thorough rewritting to make it understandable.

Author response: P value has been removed

Comment 16- Line 163. Mention the Tables you are talking at the beginning of the paragraph.

Author response: The tables are mentioned in the same paragraph

Author response: The purpose was to clarify predator performance with and without pollen

Comment 20- TAble 2. Put the units of the measures. They are days, aren’t they?

Author response: Yes, they are days. Units of measurement have been set in days.

Comment 21- The values for pollen plus eriophyd are very similar to the obtained with the eriophyd alone. As there is no variability in the parameters it is not easy to say if they are really different, but the values are very close each other and the autohors should mention this.

The values with the pollen alone are clearly lower, at least compared with the pollen plus mites.

Simplify all the paragraph because it is not neccessary to mention all the values, give the general idea and refer to table 7.

Author response: The values ​​of life parameters differ from ordinary decimal numbers. For example, the number Intrinsic rate of increase (rm) 0.242 is significantly different from the number 0.211. And so on for other parameters.

The table has been comprehensively revised according to Birch (1948).

Comment 22- Line 5. “.. palm pollen for both predators. The…”

Author response: It has been modified

Comment 23- Table 3. Eliminate letters if there is not significative differencies between treatments. Mention that point (no significative differences) at the foot of the table and when you explain the results.

Author response: Letters have been deleted. The sentence (no significative differences)  has been added at the foot of the table.

This sentence exists in the text (Tukey’s HSD test indicated that juvenile survival was not significantly affected by diet). 

Comment 24- Table 4. Headings are not equal for the two phytoseiids. Correct it.

Author response: Headings have been corrected.

Comment 25- Footnote: Letters in the row does not seem to fit the statement. And besides they are not put correctly. C. vitis a b  - C.vitis+pollen a b

Author response: C. vitis (Bb), C. vitis + Pollen (Bc) (The capital letter denotes the significance within the same column and small letter denotes the significance within the same row).

TAble 26. Correct the position of figures in colum “Dayly rate”  of P. plumifer.

Author response:  Correction has been made.

Comment 27- Footnote: Explain that the comparation is made only with females.

Author response:  Correction has been made and the sentence “The comparison is made only with females” has been added.

Comment 29- The discusiion is very extensive and prolix. The second paragraph must be split in several to gain readability. Any effort of the authors to simplify the content will make the text more readable. As has been mentioned at the beginning, it would be interesting for previewing the possible success in biological control of the two phytoseiids to know the biotic values of the prey. If authors have information of the biotic capabilities of the prey they should mention here in extend.

Author response: Some paragraphs have been deleted from the discussions section.

- The second paragraph has been divided into several paragraphs to gain readability.

Comment 30- Lines 235-236. I think it is more appropiate to rewrite the sentence as: “In conclusion, our results demonstrate that the grape erineum mite C. vitis is a suitable prey for both phytoseiids P. plumifer and E. scutalis, making them…”.

Author response: The sentence has been modified

Reviewer 2 Report

Comments and Suggestions for Authors

COMMENTS TO MANUSCRIPT Plants-3077516 v2 “Potential of two phytoseiid mites as predators of the grape eri-neum mite, Colomerus vitis”

 

The manuscript has improved greatly compared with the previous version. Nevertheless, some comments are made about the new version which need a proper answer and correction from the authors.

Particular comments to the manuscript follow:

Lines 64-66. This statement needs a reference that support it.

Lines 137-139. Mention the Table where results are showed.

Line 142. “P” in italics, and correct in other parts of the text.

Table 1. Explain clearly (in the footnote) how the statistics were made: whithin each species or the two species together.  If the analysis was made within each species (as it seems), then in E. scutalis Protonymph, Deutonymph and Overall time letters that separate the female and male are not well put: it cannot be "b" and "c". Correct.

If the statistical analysis was made with the two species together, then I do not think the analysis was correct.

 

Table 3. Preoviposition time of E. scutalis cannot be “c”, check the letters.

 

Table 4. Letters in some rows do not seem to be correct. They are not put correctly if the footnote is correct: analysis was made within the same row: C. vitis “a”     “b”  -  C.vitis+pollen “a”     “b” for each phytoseiid species. Correct.

 

Table 5. Where is the values for males in the daily rate of P. plumifer longevity?

 

Lines 78-82. Do not include the figures. Just comment them and refer to the table.

 

Line 88. How insignificant?. P=0.0210 is not insignificant. Correct and make sense the sentence. And besides, of what phytoseiid species are talking about.

Please rewrite better the paragraph.

Comment 4- Table 1. Explain clearly (in the footnote) how the statistics were made: whithin each species or the two species together.  If the analysis was made within each species (as it seems), then in E. scutalis Protonymph, Deutonymph and Overall time letters that separate the female and male are not well put it cannot be "b" and "c". Correct.

Author response: Thank you for pointing this out. The reviewer is correct, and the letters were spelled correctly. Additionally (Within each species) has been written in the footnote

Comment 5- If the statistical analysis was made with the two species together, then I do not think the analysis was correct.

There is no significant difference between C. vitis and C. vitis + Pollen for both predators, so they are coded with the letter B, this is for each column independently.

As for the row, there was a comparison between the predators and there was a significant difference in the number of eggs laid, so they were coded with the letters (b and c) when the predators fed on C. vitis. and (d and e) when predators fed on C. vitis + Pollen. In the last row, the letter c was changed to be (d) for the predator Phytoseius plumifer. The letter (d) was also changed to become (e) for the predator Euseius scutalis as shown in the table

Comment 8- Table 5. Where is the values for males in the daily rate of P. plumifer longevity?

Author response: The values for males in the daily rate of P. plumifer longevity have been added

Comment 9- Lines 78-82. Do not include the figures. Just comment them and refer to the table.

Author response: The figures have been removed

Comment 10- Line 88. How insignificant?. P=0.0210 is not insignificant. Correct and make sense the sentence. And besides, of what phytoseiid species are talking about.

Author response: The paragraph has been modified
