Model warns of new mosquito invasion in Florida

Now that the disease-transmitting mosquito Aedes scapularis has invaded the Florida peninsula, researchers have come up with a method to predict where conditions may be most suitable for its spread. When a new mosquito species capable of transmitting disease arrives and shows signs it can survive across multiple urban and rural habitats it brings the potential for public health risk. Aedes scapularis is a nonnative mosquito, just discovered in November 2020. It can transmit yellow fever virus, Venezuelan equine encephalitis virus, dog heartworm, and other pathogens to humans or other animals. It has a wide range, from Texas to parts of South America and throughout much of the Caribbean. The species is also widespread in Florida’s Miami-Dade and Broward counties.
