Which two species are listed as causing dengue fever?

• A. Ae. aegypti, Ae. albopictus
• B. Ae. hexadontus, Ae. tahoensis
• C. Ae. taeniorynchus, Ae. vexans
• D. Ae. dorsalis, Ae. squamiger

Answer: (A)

Dengue is spread mainly by mosquitoes in the Aedes genus, with two species standing out as the primary transmitters: Aedes aegypti and Aedes albopictus. These mosquitoes are particularly effective vectors because they readily bite humans, breed in small water containers near homes, and feed during the day, creating frequent opportunities to pass the virus from an infected person to others. Aedes aegypti is especially close to human environments and highly anthropophilic, while Aedes albopictus, the Asian tiger mosquito, expands the reach of transmission in many areas and can also bite humans and acquire or transmit the virus. The other species listed are not recognized as primary dengue vectors, either because they don’t bite humans as often, live in different habitats, or are associated with transmitting other diseases.
