What insect is responsible for transmitting the Zika virus?

The Aedes mosquito is the correct answer because it is known to be the primary vector for transmitting the Zika virus. This species, particularly Aedes aegypti and Aedes albopictus, thrive in tropical and subtropical climates and are notorious for their role in spreading various viral diseases, including dengue fever, chikungunya, and Zika. Their feeding habits, which include biting during the daytime, along with their proximity to human habitats, contribute to their efficiency as vectors.

In contrast, while Anopheles mosquitoes are primarily known for transmitting malaria, they are not associated with the Zika virus. Culex mosquitoes are commonly linked to diseases such as West Nile virus and encephalitis but do not play a role in the transmission of Zika. The Asian tiger mosquito, although a specific type of Aedes mosquito, refers to Aedes albopictus, which also transmits Zika but is part of the broader category of Aedes mosquitoes responsible for its spread. Hence, while the Asian tiger mosquito is relevant, the most accurate choice in this context still remains the Aedes mosquito in general, acknowledging its broader implications in vector transmission for Zika.
