New Invasive Mosquito Species Found in Florida
Scientists have discovered a new species of mosquito, Culex lactator, in at least three southern counties of Florida. This is concerning because the mosquito’s feeding habits and potential to spread diseases are not yet known.
Climate Change and Mosquitoes
The rise in temperatures due to climate change is making it easier for invasive species, like the Culex lactator, to move into areas where they previously couldn’t survive. The mosquito’s native habitat is Central and South America, but due to the changing climate conditions, it has made its way into Florida.
Invasive Mosquitoes and Disease
Mosquitoes are known to transmit diseases like West Nile and St. Louis Encephalitis, both of which can be deadly. The Culex lactator’s potential to spread disease is a concern as little is known about its habits.
Florida’s History with Invasive Species
Florida has seen the establishment of up to 17 non-native mosquito species, with 11 of them discovered in the past two decades and six within the last five years. A warming climate has aided in their proliferation and expansion of disease-carrying pests in the US.
Wildlife Concerns
Birds can harbor diseases such as West Nile virus and St. Louis encephalitis that Culex could spread by feeding on both birds and humans. However, researchers do not know if the new species is a bird feeder or how it will contribute to virus transmissions.
The Future of Culex Lactor
The future spread of this invasive species is unclear, but it may potentially move further north into Tampa Bay and Orlando. Local mosquito control experts will be looking for this new invasive species. Research does not find it to be a big threat to public health yet, but there are concerns about not knowing its habitat specifics, what diseases it may or may not carry, and how fast it may spread.
Florida’s mosquito control programs will now have to adjust to the addition of another invasive species. The discovery of Culex lactator is another example of how climate change is affecting the world’s ecosystems. As temperatures rise, more invasive species that are native to tropical areas will continue to spread into new regions.
