Question

The dengue fever is caused by the bite of which of the following mosquitoes ?

Answer & Solution

Answer: (Detailed Solution Below)

Option B: Aedes

Detailed Solution:

The correct answer is “Aedes”.

The dengue fever is caused by the bite of the Aedes mosquito, specifically the Aedes aegypti and Aedes albopictus species.

These mosquitoes are known for their distinctive white markings on their legs and a lyre-shaped pattern on the upper surface of their thorax. They thrive in tropical and subtropical climates and are primarily responsible for transmitting the dengue virus, which can lead to severe flu-like symptoms and, in some cases, can be life-threatening.

Asian tiger mosquito: Commonly known as Aedes albopictus, it is also a vector for dengue, but the term "Aedes" encompasses both Aedes aegypti and Aedes albopictus.

Culex: This genus primarily transmits West Nile virus and other diseases but is not a major vector for dengue.

Anopheles: Primarily known for transmitting malaria, not dengue.
