Lab-bred mosquitoes are flying in South Miami. It’s the latest effort to stop the type of mosquito that spreads the Zika virus.

Human skin is a cornucopia of fragrances.

The bacteria living on our skin emit more than 200 odor chemicals.

"Many of these molecules smell quite pleasant," says biologist Jeff Riffell at the University of Washington. "They smell grassy or a little bit like mushrooms. Some human scents are the same ones found in flowers."

Other chemicals — well — they aren't so nice. "They're pretty funky," Riffell says, like an overripe Brie cheese or a musty basement.

Tracking some of the world's biggest killers, via cellphone

Dec 25, 2017

Over the last few years, Haripriya Mukundarajan has gotten intimately acquainted with the world’s most efficient serial killers.

“This is Anopheles gambiae, the most dangerous animal in the world,” she says, pulling up a recording of one flying around.

The company that wants to hold the first U.S. trial of genetically modified mosquitoes in the Florida Keys and Keys residents who oppose the trial don't agree on much.

But representatives from both sides said Thursday they are happy with the recent announcement that federal oversight of the proposed trial will be moved from the Food and Drug Administration to the Environmental Protection Agency.

"We think it's a good thing," said Derric Nimmo, principal scientist at Oxitec, the company that has developed a genetically modified Aedes aegypti mosquito.

A chemical used for mosquito control in South Florida has been the source of controversy in recent weeks, after a study showed it could be linked to developmental delays in infants.

While mainland South Florida ramps up its battle against the mosquito that can carry Zika, the Florida Keys has already begun the region's most intensive mosquito control operation.

When he had a landscaping business, Bob Hartmann grew 200,000 orchids and thousands of other plants on his three acres in Southwest Ranches, about 15 miles southwest of Fort Lauderdale.

A federal judge has dismissed a request to stop aerial spraying of the pesticide Naled in Miami-Dade County, describing the plaintiffs' complaint as "poor" and recommending they get a lawyer before pursuing further legal action.

Last year, the pesticide Naled was one of several tools officials used to control mosquitoes that carry the Zika virus. Dr. Michael Hall was one of many Miami Beach residents who protested, saying Naled exposure leads to symptoms like headaches and nausea. He and other protesters also expressed fears the pesticide could have longer-term health effects.

Mosquito Control: Tips for the Rainy Season

Drain and cover. That's the message Miami-Dade County mosquito control specialists want the public to hear. 

Mosquitos can lay more than 100 eggs at a time, and they do so in standing water. Even a bottle cap of water is big enough.

Mosquitos can carry the West Nile virus and the Zika virus, among other things.

Last summer’s wave of local transmission of the Zika virus hasn’t yet bled into 2017 , but officials from Key West to West Palm Beach are gearing up for another round of mosquito control by creating new staff positions, adding more equipment and increasing outreach efforts.

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).

Florida has not had any locally transmitted cases of Zika so far in 2017. And the number of travel-related cases has fallen drastically in the dry season.

But tests of new mosquito-fighting methods are still moving forward in the Florida Keys.

The first U.S. trial of genetically modified Aedes aegypti mosquitoes — the kind that carries Zika and dengue fever — is still on track for the Keys, just not on Key Haven. That's the island that Oxitec, the company that makes the genetically modified mosquito, chose for its test site.

Florida Researchers Find 2 New Invasive Mosquitoes

University of Florida researchers say they've found two new disease-carrying mosquito species in the state for the first time.


Officials plan to release lab-reared, bacteria-infected mosquitoes in the Florida Keys in March.
