The Malagasy ecosystem is home to a multitude of mosquito species, including five formidable vectors of malaria. This disease, which continues to plague the island, has seen the number of cases increase significantly in recent years. To understand and control this worrying progression, a team of researchers from the Institut Pasteur and the IRD is entirely dedicated to the study of these formidable mosquitoes. Their objective ? Establish an effective national strategy to combat malaria.
Dr Luciano Tantely, entomologist at the Institut Pasteur, underlines the fundamental importance of mosquitoes in the balance of the ecosystem. Indeed, these insects play a crucial role in the food chain and in the preservation of biodiversity. Eliminating them is not the solution, but rather they need to be controlled effectively. It is with this in mind that researchers are carrying out in-depth studies to understand transmission cycles, biting habits and possible adaptations of mosquito vectors.
The head of the medical entomology unit at the Pasteur Institute of Madagascar, Doctor Diego Ayala, highlights the urgency of this research in the fight against malaria. Faced with an alarming increase in cases of the disease, it is essential to understand the mechanisms at play in order to better target prevention and control actions. These studies will also make it possible to assess mosquito resistance to insecticides, crucial data for adapting control strategies.
In short, research on malaria-vectoring mosquitoes in Madagascar is of capital importance for public health and the preservation of the ecosystem. A better understanding of these insects will make it possible to implement more effective control measures adapted to the reality on the ground, with the ultimate goal of reducing the prevalence of malaria on the island.
