New invasive mosquito species spreading in Florida

A close-up look at the Culex lactator collected by Lawrence Reeves, author of the manuscript. (UF/IFAS Lawrence Reeves) Scientists are expressing concern as another new mosquito species has entered the Florida tropics with the potential to transmit mosquito-borne diseases.A mosquito known only by its scientific name, Culex lactator, has already made a permanent home in at least three counties in the Sunshine State, according to the University of Florida Institute of Food and Agricultural Sciences.Faculty at the university's Florida Medical Entomology Laboratory recently published their new study in the Journal of Medical Entomology.

They discovered the species in Miami-Dade County in 2018 while they hunted for other nonnative mosquitoes. WARMER WEATHER MEANS AN INCREASE IN THESE BUGS THIS SPRINGA view of the scutum or dorsal portion of the thorax of Culex lactator. (UF/IFAS Lawrence Reeves) Lawrence Reeves, lead author of the study and an assistant professor and mosquito biologist at the university's research center in Vero Beach, said Culex lactator is found in Central America and northern South America.The Culex group of mosquitoes includes important species that transmit the West Nile and St.

Louis encephalitis viruses. "It’s too early to know whether Culex lactator will exacerbate these challenges, but the implications are often difficult to predict because not all mosquito species are equally capable of transmitting a particular virus or other pathogen," Reeves said.MALARIA FEARS RISE AS WARMING CLIMATE EXTENDS RANGE OF DISEASE-CARRYING MOSQUITOES, STUDY FINDSLawrence Reeves collecting mosquitoes from a trap in South Florida.
