Reviewer's Responses to Questions

Key Review Criteria Required for Acceptance?

As you describe the new analyses required for acceptance, please consider the following:

Methods

-Are the objectives of the study clearly articulated with a clear testable hypothesis stated?

-Is the study design appropriate to address the stated objectives?

-Is the population clearly described and appropriate for the hypothesis being tested?

-Is the sample size sufficient to ensure adequate power to address the hypothesis being tested?

-Were correct statistical analysis used to support conclusions?

-Are there concerns about ethical or regulatory requirements being met?

Reviewer #1: See marked-up PDF and Review PDF

Reviewer #2: The manuscript describes a trial of the efficacy of transgenic male Aedes aegypti in suppressing a cage population of a strain (OX513A) derived from eggs collected in a small village close to Jalna, a city in Maharashtra State in India.

Despite an immense amount of detailed description, extensive data and exhaustive statistical analysis I regret to say that I see little difference between this study and other cage studies using the same transgenic strain that have been published in the past 15 years. The only difference is that a local strain was used.

One piece of information, however, intrigues me: 10.9% of females of the local strain mated with both local males and OX513A. Although there are reports of a second mating a few hours after the first, it is generally assumed that the species is monogamous.

In my opinion, the manuscript should only be accepted if whittled down to a short report presented as confirmatory to previous studies. On the other hand, I suggest that further exploration of the question of polygamy could be interesting.

(Details of the OX513A transgenic strain can be accessed at: https://www.oxitec.com/en/public-health)

You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. If requesting major revision, please articulate the new experiments that are needed.

Reviewer #1: (No Response)

Reviewer #2: The manuscript describes an experiment to assess the capacity of a transgenic strain of Aedes aegypti to suppress a population of wild-type insects in a large outdoor containment facility.

The study was well-designed and the results well-presented (albeit perhaps with an excess of detail in the body of the manuscript).

I consider it worth publishing in its present form but I suggest there should be some clarification of the strain used.

This was the original “1st generation Friendly “strain, OX513A. This can now be considered obsolete, replaced by the “2nd generation strain, OX5034".

https://www.prnewswire.com/news-releases/oxitec-transitioning-friendly-self-limiting-mosquitoes-to-2nd-generation-technology-platform-paving-way-to-new-scalability-performance-and-cost-breakthroughs-300756465.html

The difference is important because whereas the original strain was lethal to all the offspring of females mated with the transgenic strain, the new strain is only lethal to the females; half of the male offspring carry the gene and survive to pass it on to the next generation.

I do not suggest that the study is obsolete but suggest that this difference should be made clear.

Dear Dr Patil,

Thank you very much for submitting your manuscript "Elimination of a closed population of the yellow fever mosquito, Aedes aegypti, through releases of self-limiting male mosquitoes" for consideration at PLOS Neglected Tropical Diseases. As with all papers reviewed by the journal, your manuscript was reviewed by members of the editorial board and by several independent reviewers. The reviewers appreciated the attention to an important topic. Based on the reviews, we are likely to accept this manuscript for publication, providing that you modify the manuscript according to the review recommendations. I agree with the reviewer that the number of figures could be reduced, both by creating multi-panel figures and moving things to a supplement (maybe Figs 1-4?). A minor thing is that Figure 3 should not say 'No Fluorescence' as it is clearly fluorescing. Maybe say 'auto-flouresence'.

Please prepare and submit your revised manuscript within 30 days. If you anticipate any delay, please let us know the expected resubmission date by replying to this email.

When you are ready to resubmit, please upload the following:

[1] A letter containing a detailed list of your responses to all review comments, and a description of the changes you have made in the manuscript.

Please note while forming your response, if your article is accepted, you may have the opportunity to make the peer review history publicly available.
