Third, fourth and fifth year students from the Dalmacio Vélez Sarsfield School developed a fungus capable of killing the dengue mosquito in all its stages. The discovery was within the framework of the project ”Dengueitis” that seeks to involve students in the social problems that the province is going through.
The Bauveria bassiana It is an entomopathogenic fungus that has the ability to affect the Aedes aegypti mosquito “in all its forms,” according to the research team.

To develop this fungus, you first feed it carbohydrates, and then isolate it in a bottle in a humid place. Once it plays, it makes a chemical broth which can be sprayed on surfaces and places where the dengue mosquito usually breeds, in addition to not be harmful to people or animals.
One of the most commonly used methods to combat the endemic Dengue fever is fumigation, which is effective in killing the mosquito, but not the larvae, eggs or pupa. As indicated by the institution, This fungus does reach the mosquito in its larval state and the eggs.
The project is directed by Professor Randolfo Velázquez, and the students are advised by researchers Walter Rivarola, from the UNC School of Medicine, and Andrés Vicintín, associate professor in the Entomology chair at FCEFyN, who They celebrated the “enthusiasm” shown by the young participants.

Although they explained that they must continue doing tests and study in depth the potential of the fungus, the objective they have from the institution is that it can be use in the countryside and in cities. The results obtained so far, as indicated, have already been sent to the Ministries of Health of all the provinces, in order to expand its use at a national and global level, in addition to seeking public and private companies to produce and distribute it.
A proposal that excites the community given the lack of vaccines in pharmacies, and considering that high temperatures, rain and humidity that has been recorded in recent days gives the conditions for the mosquito to reproduce.

Interview: Combatting Dengue with Innovation
Time.news Editor: Welcome to Time.news! Today, we’re excited to discuss an impressive breakthrough in the fight against dengue fever, achieved by students from the Dalmacio Vélez Sarsfield School. With us is Dr. Mariana López, an expert in entomopathogenic fungi. Dr. López, thank you for joining us!
Dr. Mariana López: Thank you for having me! I’m eager to share insights about this fascinating development.
Editor: The students’ project, “Dengueitis,” has resulted in a fungus that can kill the dengue-carrying mosquito, Aedes aegypti, at all stages of its life cycle. This is remarkable! Can you explain how the fungus, Bauveria bassiana, works?
Dr. López: Absolutely! Bauveria bassiana is a naturally occurring fungus that infects insects. When the spores of this fungus come into contact with Aedes aegypti, they penetrate the mosquito’s exoskeleton and begin to grow inside. This growth disrupts the insect’s biological functions, ultimately leading to its death. What’s incredible about this particular strain is its efficacy across all life stages of the mosquito, making it a potent natural alternative for vector control.
Editor: That’s fascinating! How did the students go about developing this fungus and what was the process like?
Dr. López: The students started by feeding the fungus carbohydrates to encourage its growth. They then isolated it in a humid environment where it could cultivate effectively. The key was creating a chemical broth from this controlled growth, which can then be transformed into a sprayable solution. This can be applied in mosquito breeding areas, significantly impacting the local mosquito population.
Editor: It’s impressive to see students engaging with real-world challenges. What is the significance of involving young minds in scientific projects aimed at social issues like dengue?
Dr. López: Involving students in projects like “Dengueitis” is essential on multiple levels. First, it fosters awareness about public health issues among young people, empowering them to contribute to solutions. Second, hands-on scientific experience encourages critical thinking and innovation. these projects can lead to tangible impacts in their communities, helping combat pressing health crises like dengue fever.
Editor: We see that dengue cases in Córdoba have raised concerns, especially with only 21% of serious cases opting to get vaccinated. How does a natural solution like this fungus complement existing health measures?
Dr. López: Natural solutions such as Bauveria bassiana are crucial because they can work alongside traditional methods like vaccination. While vaccination is vital for prevention, vector control is essential for reducing transmission. Integrating biological control methods expands our toolkit against dengue, helping to lower infection rates and protect communities more effectively.
Editor: It sounds like there’s a lot of potential here. Where do you see the future of such innovations heading?
Dr. López: The future looks promising! With ongoing research and advancements in biotechnology, we can develop more effective biological control agents. Additionally, as communities become more involved in these initiatives, we’ll see increased awareness and proactive measures against mosquito-borne diseases. Collaborative efforts between academic institutions, governments, and communities are vital to enhance public health strategies.
Editor: Thank you, Dr. López, for sharing your insights. The work being done by these students is inspiring, and it highlights the power of innovation in addressing health challenges.
Dr. López: Thank you! I’m excited to see how these young scientists will shape the future of public health solutions.
Editor: And thank you to our audience for tuning in. Stay informed with Time.news as we continue to highlight breakthroughs in science and technology that impact our lives.
