Aedes aegypti is a major mosquito vector of dengue, yellow fever, chikungunya, and Zika viruses.
Often called the yellow fever mosquito, Aedes aegypti is recognizable by pale markings on its dark legs and a lyre-shaped pattern on the upper thorax. Unlike many mosquitoes, it is strongly adapted to human environments and commonly breeds in small containers of standing water around homes.
Females bite because they need protein for egg development. The species can acquire a virus while feeding on an infected person and later transmit it when it bites another host. It is a particularly important urban vector because it frequently feeds on humans and can live close to dense populations.
Aedes albopictus, the Asian tiger mosquito, can also transmit several of these viruses, so it is not a nonsensical alternative. However, the question’s standard textbook pairing of dengue, yellow fever, chikungunya, and Zika points to Aedes aegypti. Anopheles mosquitoes are best known for malaria transmission, while Culex pipiens is associated with other pathogens.
