Which Mosquito Species In Arizona Pose A Health Threat To Residents? And Which Species Can Become A Nuisance Within Homes In The State?
The United States is home to 150 mosquito species, more than 40 of which can be found in the state of Arizona. It may be hard for some residents to believe that so many mosquito species inhabit the state, but most of these species are completely absent from urban areas. Culex mosquitoes and floodwater mosquitoes are the two main categories of mosquito in Arizona, but the non-native aedes aegypti mosquito, which is responsible for the greatest number of mosquito-borne disease cases in the Americas, has also established a presence in urban and suburban areas in the state. There exists six mosquito pest species that pose a health threat to residents of Arizona, and some can even become a nuisance within homes and yards.
The six medically significant mosquito species that are present within populated areas of Arizona are western encephalitis mosquitoes, southern house mosquitoes, yellow fever mosquitoes, malaria mosquitoes, inland floodwater mosquitoes, and dark rice field mosquitoes. The southern house mosquito can be identified by a design on its abdomen that consists of five distinct lines. Not only are these mosquitoes a nuisance due to their large swarms and the loud buzzing noises that they produce, but they also pose a health threat to both humans and pets. This species is a vector for the west Nile virus and St. Louis encephalitis, and they can transmit nematodes that cause dog heartworm in pets and several encephalitis viruses in humans.
The inland floodwater mosquito is one of the most abundant mosquito species in the world and they cause more nuisance infestations than any other mosquito species. These mosquitoes are also notable for inflicting repeated bites and they can spread west Nile virus, western equine encephalitis, St. Louis encephalitis, and dog heartworm. The inland floodwater mosquito attacks humans in large swarms at dusk, and they can be recognized for the pale brown V-shaped design on their abdomen. These mosquitoes are particularly numerous in residential and urban areas of southern Arizona.
