Which mosquito feeds on infected birds and can spread West Nile virus to humans?

Culex pipiens is recognized as a significant vector in the transmission of West Nile virus. This mosquito species is particularly known for its feeding habits, which include taking blood meals from infected birds, primarily those in the Corvidae family, such as crows and jays. When Culex pipiens feeds on an infected bird, it can acquire the virus and later transmit it to humans through its bite.

The role of Culex pipiens as a vector highlights the ecological connection between avian populations and human health, as the virus amplifies in bird populations before being transferred to humans. This cycle underlines the importance of vector control strategies that target the habitats and breeding sites of this mosquito to reduce the risk of West Nile virus transmission. Understanding these dynamics is crucial for public health efforts aimed at preventing outbreaks.

Other mosquito species mentioned, such as Aedes aegypti, Anopheles gambiae, and Culiseta melanura, do not serve the same primary role in transmitting West Nile virus to humans. Aedes aegypti is better known for carrying diseases like dengue and Zika, while Anopheles gambiae is a primary vector for malaria. Culiseta melanura typically feeds on birds but does not significantly contribute to
