Distribution of Culex coronator in the USA

Abstract

In 1920, Culex coronator was reported from San Benito, Texas, and later in Arizona, New Mexico, and Oklahoma. In 2005, this species was reported to be spreading across the southeastern USA. Now reported in 14 states, it has been found as far north as northern Oklahoma; Memphis, TN; and Suffolk, VA. The public health significance of Cx. coronator is not firmly established, even though it has been implicated as a potential vector of several arboviral diseases. This study aims to document additional Cx. coronator county-level records, to provide information about its continued expansion across the southern USA, and to provide a short research update into its vector potential. Data acquired through multistate collaborations and author collections resulted in 146 new county records from Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, and Texas. No new county records were presented for Arizona, New Mexico, Tennessee, or Virginia, which had previously reported this species. With these new data, this species has been documented in 386 counties in 14 states of the continental USA.

Seasonal and hourly diversity patterns of anthropophagous female mosquito species in a semi-conserved area at the southern Mexico

“…Mosquito species in this genus are known to be vectors of medical and veterinary relevance. Pathogens such as WNV, St. Louis virus (SLV), ZIK [89][90][91], and VEE [92] have been found in wild specimens. For example, Baak-Baak et al [93] [96][97][98], that infect humans, birds, primates and other wild vertebrates.…”

“…Between the 1920s and 1970s, Culex coronator was reported from several states in the western and central United States (Arizona, New Mexico, Louisiana, Mississippi, Oklahoma, and Texas). In the early 2000s, the species expanded its United States distribution eastward, and in 2000s and 2010s, it was reported for the first time as far east as Florida and Virginia (Sames et al 2021).…”
