Aedes aegypti, traps, free artificial containers, deseases
This study investigated the presence and the breeding sites preference of the Aedes aegypti mosquito in the surroundings of the Municipal School of Minas Gerais, Urca, city of Rio de Janeiro, Rio de Janeiro, Brazil. The presence of Aedes aegypti in an urban area represents a potential risk of the interrelation of this mosquito species with the population because we know that Aedes aegypti is the mosquito that transmits Dengue, Urban Yellow Fever, Chikungunya and Zika Virus diseases. Samples for the study were obtained by collecting mosquito larvae from different containers, such as artificial breeding sites (water tanks, tanks, trash, tires, etc.) and traps, made with 2-liter transparent PET bottles, placed at four school sites and two in areas around the school in the period of six months (June to November). The results showed that artificial deposits as breeding sites are more positive for mosquitoes, including Aedes aegypti. Black or dark disposal products and shady water tanks, characterized by artificial deposits, were preferred for this mosquito species.

The results showed that artificial deposits as breeding sites has a higher positivity for Aedes aegypti. Black or dark discard products, characterized by artificial deposits, were preferred for this species of mosquito. Keywords: Aedes aegypti, artificial deposits, traps, breeding sites, diseases.

This project is very well done. The topic is very important and the students did a great job showing this. The results are very clear. Nice job!

The enthusiasm of the students is obvious in the report. I also enjoyed the video which is well done. Just one curiosity question, is there anything the students who participated think they can do to reduce the mosquito population now that they have the data and results? Shirley Leow, USA

Yes, we are doing prevention campaigns in the school community and the surrounding area with flyer distribution to sensitize people about the need to mitigate mosquito breeding sites and the diseases transmitted by them.

This is a great research project, especially with a one year data using MHM App. I really enjoyed reading your report and it has great community impact on how to control mosquito in your area. Here are my questions.
1. Why did you get the high number of mosquito larvae in 26/07/2017? Would the number of dengue incidences increased in the following month?
2. In order to be better comparison between free breeding sites and artificial deposits, you should place artificial deposits next to the free breeding sites and see if female mosquitoes prefer to lay eggs in one or the other.
3.Is there any other ways that you could improve your experimental design in order to better proof your hypothesis? For example, comparing the number of positive containers with total containers (i.e. calculating container index).
Excellent project, keep doing all the great work.

1 - It was an isolated case of concentration of stagnant water in the paint container, which the painters left on top of the roof. did not increase the cases of dengue because we took them before the larvae hatch, there were only larvae of the first and second stages inside the container found.

2 - Thanks for the ideas and tips, to place artificial deposits next to the free breeding sites and see if female mosquitoes prefer to lay eggs in one or the other is being our project in the biennium 2018-2019.

3 - The comparison of the number of positive containers with total containers is also part of this extension of our project in the biennium 2018-2019.
Thank you very much for the interest and support, your tips and ideas were very important for the second phase of our project.
