ARMADILHA PARA O MOSQUITO DA DENGUE - VÍDEO COMPLETO - PASSO A PASSO.

Summary

In this video, biologist Rodrigo Barbassa discusses the dengue fever epidemic in São Paulo and introduces a simple, effective way to combat it: a DIY mosquito trap. The trap, made from a PET bottle and basic materials, attracts and captures dengue-carrying mosquitoes. Rodrigo explains how the trap works, the importance of sealing it properly, and how organic matter, such as rice or leaves, is used to attract mosquito larvae. He emphasizes the need for regular monitoring and cleaning, offering this trap as an accessible and effective tool to help reduce mosquito populations and prevent dengue.

Takeaways

• 😀 The state of São Paulo declared a state of emergency on March 5, 2024, due to a dengue epidemic.
• 😀 The state will now have the ability to respond more quickly with increased funding, personnel, and supplies to tackle the dengue crisis.
• 😀 As of the recording, there are approximately 20,550 probable cases and more than 30 confirmed deaths from dengue in São Paulo.
• 😀 The video aims to teach people how to create a simple homemade trap to help combat dengue by capturing mosquitoes.
• 😀 The trap is made using a PET bottle (preferably Coca-Cola), a box cutter, scissors, adhesive insulating tape, sandpaper, and micro tulle.
• 😀 The main components of the trap are the funnel (top of the bottle) and the base, which are sealed together with the insulating tape.
• 😀 Organic matter (e.g., leaves or rice grains) is placed inside the trap to attract mosquito larvae, providing food for their growth.
• 😀 The trap works by attracting mosquitoes to lay eggs on the funnel grooves. The larvae develop in the water inside the trap.
• 😀 After the larvae mature, they turn into pupae and then into adult mosquitoes. Some adults may be trapped inside the sealed funnel, preventing them from escaping.
• 😀 The trap should be placed in a shaded, cool area, as mosquitoes are attracted to dark, low-lying places for egg-laying.
• 😀 To effectively control mosquito populations, regularly check the trap, and if larvae are present, add chlorine to kill them. Then wash and reuse the trap.

Q & A

What is the main objective of the video?

The main objective of the video is to teach viewers how to create a simple mosquito trap at home to help combat the spread of dengue fever.

Why is the state of São Paulo in a state of emergency regarding dengue fever?

The state of São Paulo declared a state of emergency on March 5, 2024, because of a dengue epidemic, with over 20,000 probable cases and more than 30 confirmed deaths.

What materials are required to make the mosquito trap?

The materials required to make the mosquito trap include a PET bottle (preferably a Coca-Cola bottle), box cutter, scissors, insulating tape (electrical tape), sandpaper, micro tulle (thin fabric), and organic matter (such as leaves or rice grains).

Why is a Coca-Cola bottle recommended for making the mosquito trap?

A Coca-Cola bottle is recommended because its design features a nozzle that forms a natural funnel shape, which is ideal for the trap's construction.

What is the purpose of the grooves inside the funnel of the bottle?

The grooves inside the funnel help attract mosquitoes and facilitate the evaporation of water, creating a favorable environment for the mosquitoes to lay their eggs.

What kind of organic matter should be used inside the trap?

The organic matter used should be small and non-fermenting, such as leaves or a few grains of rice. This organic matter serves as food for the larvae once they hatch.

How does the trap work to attract and capture mosquitoes?

The trap attracts mosquitoes by using water and the evaporation process. The mosquitoes are drawn to the water to lay their eggs, which then hatch into larvae that are trapped inside the bottle. Adult mosquitoes may also become trapped as they emerge from the pupal stage.

What role does the tulle play in the mosquito trap?

The tulle acts as a barrier, allowing mosquito larvae to pass through to the water while preventing adult mosquitoes from escaping the trap once they are trapped inside.

Why is it important to seal the trap well?

It is important to seal the trap well to prevent mosquitoes from escaping. Any gaps in the trap could allow mosquitoes to proliferate, making the situation worse instead of helping control the population.

What should you do if you find mosquito larvae in the trap?

If mosquito larvae are found in the trap, chlorine should be added to kill them. Afterward, the trap should be cleaned thoroughly before being resealed and reused.
