Dengue in Florida!

Another great story about Dengue, this time right near us in Florida (Key West).  Listen to it here.  Will we have to worry about Dengue in southern Mississippi?  Well Aedes aegypti has been locally extinct from the area since at least the 1990s, so we might rest easy knowing that the main vector of the disease is not around to transmit it.  What is a concern is that Aedes albopictus, a somewhat less important vector of Dengue, is the most common container species in the southern US. 

 
Our recent work with Aedes aegypti has shown considerable tolerance to salt over a recent invader, Aedes albopictus.  This could help explain why Aedes aegypti is doing better in some coastal areas.
