mosquito borne illness

On a hot, sunny Saturday morning at the Upper Tampa Bay Regional Public Library, Kathy and Dani Dahlberg walk up to a white truck holding portable fish tanks that emit a loud hum.

The new homeowners are trying to describe the size of their pond to Hillsborough County Mosquito Control officials.

Last year's Zika outbreak in Miami likely started in the spring of 2016, with the virus introduced multiple times before it was detected, researchers say. And most of those cases originated in the Caribbean.

As the rainy season returns to South Florida and the fight against Zika gears up, the Florida Keys Mosquito Control District Tuesday began a first-in-Florida trial of a control method that uses bacteria to reduce mosquito populations.

The district will release 20,000 male mosquitoes infected with the Wolbachia bacteria twice a week for the next 12 weeks. The releases will take place in a 10-acre test site on Stock Island,  and mosquito traps there will be compared with a similar-sized control area nearby (but separated by a buffer).
