Which Anopheles species is most common and widespread in the southeastern United States?

Anopheles quadrimaculatus is the most common and widespread Anopheles species in the southeastern United States, playing a significant role in the transmission of malaria in this region. This species thrives in warmer, humid environments typical of the southeastern U.S., where it can often be found in various habitats, including floodwater and stagnant bodies of water that serve as breeding grounds.

Its adaptability to different ecological settings enhances its geographical distribution, enabling it to establish populations across substantial areas. Along with its ability to breed in a range of water sources, Anopheles quadrimaculatus is also notable for its resistance to certain control measures, making it a persistent challenge in public health pest management. Understanding the characteristics and behavior of this species is crucial for effective malaria prevention strategies in areas where it is prevalent.
