Biosourced repellents and attractants for mosquito control
Innovative biosourced repellents and attractants have been developed using chemically modified terpenes and coumarins, offering effective mosquito control with reduced ecological impact. These solutions are validated in insectary tests and are nearing commercial formulation.
Overview
This research presents a cutting-edge approach to mosquito control using biosourced repellents and attractants. By chemically modifying natural terpenes like carene, pinene, and limonene, we have developed new compounds with potent repellent properties. Additionally, coumarins and chromones have been identified as selective attractants, targeting specific mosquito vectors such as Aedes and Anopheles. This innovative solution provides effective control of dangerous mosquito species, minimizing ecological impact.
Technical specifications
Key features:
- Repellents: Modified terpenes exhibit greater repellent activity than PMD, a common repellent ingredient.
- Attractants: Specific coumarins and chromones selectively attract Aedes and Anopheles mosquitoes, aiding in targeted elimination.
- Testing Methods: Evaluation conducted using tunnel olfactometers, cage systems, and volunteer testing (following WHO protocols).
- Synthesis and Analysis: Organic synthesis and structural analysis performed at Lyon Laboratory, with mosquito testing in Madagascar.
Technology readiness level
The technology is currently at TRL 5, having been validated in controlled insectary tests and volunteer studies. Future steps include completing volunteer evaluations, studying synergistic effects with commercial products, patent filing, and developing a commercial formulation within the next six months.
