Submission received: 4 November 2020 / Accepted: 9 November 2020 / Published: 14 December 2020
We have recently been made aware by the reviewer and the Journal Editorial Offices of the following weaknesses in our recent paper [1]:

1. Introduction

Introduction, second paragraph, line 14 currently reads as follows:
[This behavior suggests]
We would like to make the following corrections:
[This suggests]
Introduction, fifth paragraph, line 17 currently reads as follows:
[It is important to highlight that in environmental conditions favorable for the constant presence of brood in the hives throughout seasons, such as in the Mediterranean area, it is crucial to correctly estimate the percentage of cells infested by one or more mites.]
Add at the end of the sentence the reference [34].
[It is important to highlight that in environmental conditions favorable for the constant presence of brood in the hives throughout seasons, such as in the Mediterranean area, it is crucial to correctly estimate the percentage of cells infested by one or more mites [34]]

2. Materials and Methods

At the end of the section Materials and Methods add the sentence:
[Data availability: The complete datasets analyzed during the current study are available from the corresponding author on reasonable request.]

3. Results

Starting from the line 19 of the results section remove the two following consecutive sentences:
[Consequently, once the number of mites passing from the phoretic to the reproductive phase is established and once the number of cells available to be invaded by the mite is known, e.g., by using a predictive model [17,34], it could be possible to define the distribution of female mites in brood cells for each level of infestation.]
[Starting from the studies of Martin [12] and DeGrandi-Hoffmann and Curry [16], which showed the effects of infestation on mite reproduction rate and bee longevity, we can highlight the additional effects of multi-infestation.]
At the beginning of the next sentence, replace:
[Therefore]
with
[Considering]
Results line 31: Remove the sentence:
[These data could also be used to improve the models on the Varroa dynamic]

4. Discussion

Discussion, first paragraph, line 7:
Add the following sentence and add a new reference 35 [2]:
[This phenomenon also has important effects on the genetic structure of the population of Varroa. In fact, as observed by Beaurepaire et al. [35], the increase in the co-infestation rate of brood cells also coincides with an increase in the recombined lines in the mite populations. Therefore, if treatments against Varroa are carried out before the recombination phase has taken place, the inbreeding will greatly promote the fixation of the alleles for acaricide resistance [35]].
Discussion, third paragraph, line 2
Replace the sentence:
[In fact, based on our findings, we can provide significant correction factors, previously unknown in the literature, to define the evolution of Varroa infestation, better representing the behavior of the mite in apiary conditions]
with:
[In fact, based on our second-degree polynomial curves it could be possible to define the distribution of female mites in brood cells and their rate of reproduction for each level of infestation. Therefore, these equations provide significant correction factors, previously unknown in the literature, to define the evolution of Varroa infestation, better representing the behavior of the mite in apiary conditions]
Discussion, third paragraph, line 5 add the follow sentence
[In addition, the information obtained in the reduction of adult bee longevity as a function of the average number of mites per infested cell, could be used to better understand the effects of the increasing infestation levels on bee population dynamic.]
Discussion, fifth paragraph, line 5:
The indication of reference 35 has to be change in reference 36.
