Research published in the Journal of Experimental Biology indicates that yellow fever mosquitoes (Aedes aegypti) can learn to associate the scent of DEET with food, potentially reducing the effectiveness of this common insect repellent. The study highlights the need for ongoing research to adapt mosquito control strategies.
- 01Mosquitoes can learn to associate DEET with food, which may lead them to seek it out instead of avoiding it.
- 02The study focused on the yellow fever mosquito, a significant vector for diseases like dengue and Zika.
- 03Using Pavlovian conditioning, researchers trained mosquitoes to associate DEET with a food reward.
- 04Over 60% of mosquitoes attempted to bite when exposed to the scent of DEET after training.
- 05Regular reapplication of DEET is recommended to maintain its effectiveness against mosquitoes.

A recent study published in the Journal of Experimental Biology reveals that yellow fever mosquitoes (Aedes aegypti) can learn to associate the scent of DEET, a common insect repellent, with food. Researchers trained mosquitoes using Pavlovian conditioning, demonstrating that when exposed to DEET while feeding, the insects began to associate the chemical with a food reward. In trials, over 60% of trained mosquitoes attempted to bite when they smelled DEET. This learning ability suggests that repeated exposure to DEET could diminish its effectiveness as a repellent. The study emphasizes the importance of understanding mosquito behavior to improve public health strategies, especially as climate change increases the prevalence of mosquito-borne diseases. Researchers recommend regular reapplication of DEET, particularly in tropical areas where disease risk is high, to ensure continuous protection against these pests.
