Scientists Accidentally Found a Weird New Way to Stop Mosquitoes From Mating
VICE • • health
Key Points:
- Research from Yale University reveals that garlic, specifically the compound diallyl disulfide, can repel mosquitoes from each other by activating a taste receptor called TrpA1, which triggers a sense of fullness and reduces mating and egg-laying behaviors.
- Unlike previous beliefs that garlic might repel mosquitoes from humans, the new findings suggest its primary effect is on insect-to-insect interactions, inhibiting reproduction rather than acting as a direct repellent.
- The study showed that this effect occurs in fruit flies, tsetse flies, and Aedes mosquitoes—the latter being significant due to its role in transmitting diseases like yellow fever, dengue, and Zika virus.
- Wasps were not affected by garlic because they lack the TrpA1 receptor, highlighting the specificity of the compound's impact on certain insect species.
