Brazilian Researchers Develop Unique Mosquito Control Method Amid Dengue Epidemic

In an effort to combat the spread of dengue fever, a group of Brazilian researchers has developed a unique method that uses the same mosquito that transmits the disease as a tool. By placing containers filled with water and cloth impregnated with larvicide in breeding sites, they hope to control the mosquito population amidst the worst epidemic of dengue fever in Brazil’s history.

The research project, led by Professor Rodrigo Gurgel from the University of Brasilia, has been implemented in heavily affected areas such as the Structural City in Brasilia. Residents like Manoel dos Santos have witnessed a rise in dengue cases during the rainy season. The larvicide stations and tubes installed in 150 houses in this neighborhood have shown promising results in reducing the mosquito population.

The effectiveness of this method has led to its recommendation by the Ministry of Health for use in Brazilian municipalities to control the Aedes aegypti mosquito population. It is a cost-effective solution that has already been implemented in cities across five states in Brazil. The rise in dengue deaths in Brazil has been attributed to factors such as climate change, with warmer temperatures and increased rainfall creating ideal breeding conditions for mosquitoes.

Professor Gurgel also emphasizes the importance of public awareness and preventive measures in controlling the spread of dengue fever. He stresses that a large percentage of breeding sites are found inside homes, indicating the need for residents to be diligent in eliminating standing water where mosquitoes can breed. This innovative approach offers a sustainable and effective solution to combating the dengue epidemic in Brazil.
