GAINESVILLE, Fla. — Mosquitoes aren’t just a nuisance, they’re also an economic and health concern, say University of Florida researchers.

July, August, and September are peak months for mosquito activity in Florida, and the state spends about $151 million each year trying to control the biting insects.

Controlling mosquitoes is important for economic development and tourism, said Jonathan Day, a University of Florida medical entomology professor at UF’s Florida Medical Entomology Lab in Vero Beach.

GAINESVILLE, Fla. — University of Florida researchers are finding new ways to thwart crop-devouring pests — by being good listeners.

High-tech acoustic equipment makes it possible for them to listen in as insects gnaw on grapevine roots, making it much easier for vineyard owners to know where to focus their efforts against the pest called the grape root borer.

Will Sanders, a former UF entomology graduate student, conducted much of the research and outlines the project in the current issue of Florida Entomologist. Using sound to target the pest could one day save vineyard owners money and pay off for consumers in lower costs for grapes and wine, he said. Grapes are a $20 million annual industry for Florida.

GAINESVILLE, Fla. — Visitors to University of Florida nature trails can now hear an ancient form of communication — insect songs — using one of the latest communication technologies.

Seven educational stations in UF’s Natural Area Teaching Laboratory now feature signs marked with QR codes, the square, black-and-white patterns that are starting to appear in print advertising. By scanning the signs with a mobile device, visitors can access digital recordings of katydids and crickets native to the area.

UF study finds artificial reefs are economic boon; enjoy widespread public support

GAINESVILLE, Fla. — A newly released University of Florida study of artificial reef use in six southwest Florida counties shows the structures lure a lot more than fish.

The reefs, which provide habitat for popular sport fish and other marine life, pulled more than $253 million into the region during one year, the study found. Though it costs nothing more than a saltwater fishing license to use the submerged structures as a fishing spot, anglers spend money on food, lodging, fuel, tackle and other necessities.

The UF and Florida Sea Grant study looked at money generated by artificial reefs in Pinellas, Hillsborough, Manatee, Sarasota, Charlotte and Lee counties in 2009. Researchers found that $136 million came from residents, while $117 million was spent by visitors.

GAINESVILLE, Fla. — The University of Florida has officially partnered with a National Science Foundation-funded program to allow measurements and data collection related to the Earth’s ecological health to occur on UF’s 9,100-acre Ordway-Swisher Biological Station property in Putnam County.

The project, known as the National Ecological Observatory Network, or NEON, is a 30-year, continental-scale program to track ecological responses to environmental shifts such as climate change, land-use modifications and invasive species introductions.

The project includes 20 core sites that represent different areas of North America. The Ordway-Swisher site near Melrose will serves as the core site for NEON’s Southeastern domain, which stretches from North Carolina to Texas.
