Tracking Aedes aegypti across the Ages

Mosquito-borne diseases have plagued humanity for centuries, and a prolific offender has been Aedes aegypti, commonly known as the "yellow fever mosquito." Despite the yellow-fever moniker, it is also a potent carrier of dengue, chikungunya, and Zika viruses.

Writing in BioScience, Dr. Jeffrey Powell and his colleagues describe recent work in tracking the spread of this important vector. Using newly available genomic techniques, they cross-referenced the historical divergence of A. aegypti populations with known records of ship movements and disease spread. The results paint a picture of a species that traversed slave and other trade routes to the New World and beyond.

In this episode of BioScience Talks, Powell joins us to discuss his work and to elaborate on the evolution and movements of this deadly "domesticated" mosquito species.
