Which mosquito species is known for transmitting Dengue fever?

The mosquito species known for transmitting Dengue fever is Aedes aegypti. This species is particularly significant because it thrives in tropical and subtropical climates, often living in close proximity to human dwellings, which enhances the likelihood of disease transmission. Aedes aegypti is a preferred breeding ground in artificial containers where water collects, such as flower pots, buckets, and discarded tires, all of which are common in urban environments.

This species is not only linked to Dengue fever but also to other viral diseases such as Zika, West Nile, and chikungunya, making it a major public health concern. Its feeding behavior, as well as its ability to breed in small amounts of stagnant water, contributes to its effectiveness as a vector for these diseases.

In contrast, the other mosquito species listed are associated with different diseases. Anopheles gambiae is primarily known for transmitting malaria, while Culex pipiens is mainly a vector for West Nile virus and other encephalitis viruses. Culiseta morsitans is generally not associated with major human pathogens. Thus, Aedes aegypti stands out as the key species responsible for the spread of Dengue fever.
