GAINESVILLE, Fla. — Brain activation may reveal people who are less certain about a product and indicate they are more easily swayed by an ad, a University of Florida researcher says.
In a study published today in the journal PLOS ONE, researchers found that activation of the prefrontal cortex of the brain identifies people who are more responsive to campaign advertisements.
Studies in social sciences, including agricultural economics, often rely on survey data, which counts on participants’ honesty. But tracking blood flow in the brain gives much more tried-and-true data, said Brandon McFadden, a UF assistant professor of food and resource economics and one of the researchers for the study. This study may help researchers understand brain function while people decide what to buy, he said.
“This allows us to peek behind the curtain,” McFadden said.
GAINESVILLE, Fla. — Low-altitude aerial images can detect laurel wilt, a devastating avocado disease, giving growers an early way to identify diseased trees and perhaps help reduce losses to the $100 million-a-year economic impact avocados provide Florida.
Reza Ehsani, an associate professor in agricultural and biological engineering at the UF/IFAS Citrus Research and Education Center in Lake Alfred, used a multi-spectral camera that distinguishes between laurel wilt-affected trees and healthy ones.
Images taken with the camera from a helicopter have significant implications in the management of this important disease and for the commercial avocado industry in Florida. Ehsani said he expects the Federal Aviation Administration to open U.S. airspace for commercial use of unmanned aerial vehicles, which could be equipped with such cameras, by 2017.
“Ultimately, we think that small UAVs, equipped with the right multi-band camera, can be used for scouting for this disease, which could potentially be very cost-effective,” Ehsani said. “The results of this study will enable growers or service companies that use UAVs to detect this disease at an early stage.”

Apopka, Fla. — Powdery mildew and black rot are two scourges of grape growers, but University of Florida researcher Dennis Gray is developing disease-resistant grapes, using what he calls “precision breeding” to create these super varieties.
Gray, a developmental biologist with UF’s Institute of Food and Agricultural Sciences, has successfully bred Thompson Seedless, Seyval Blanc and Syrah that resist mildew and fungus. Those are just three of only 35 grape varieties that accounted for 66 percent of the world grape acreage in 2014, he said. (more …)

IMMOKALEE, Fla. — The backhoes are ready and rebar marks off where new walls will stand as the University of Florida’s Southwest Florida Research and Education Center gets ready to break ground officially on a 7,000-square-foot expansion Thursday. (more …)
MAITLAND, Fla. – The New Varieties Development & Management Corporation has scheduled statewide grower meetings for May to launch FAST TRACK’s third suite of UF/IFAS-developed experimental citrus selections.
This new suite features four seedless easy-peel mandarin selections: UFGlow, UFSunrise, UFDawn and 7-6-27.
In addition, the UFGlow, UFSunrise and UFDawn varieties are mess-free – meaning your hands remain dry — early maturing and cold tolerant. Variety 7-6-27 has generated greater interest than any previous UF mandarin release at UF’s Citrus Research and Education Center Fruit Display Days, both in-state and internationally, as a result of its very early season of maturity, excellent color and flavor, and a potentially higher degree of tolerance to citrus greening.
Interested commercial citrus growers should plan to attend one of the meetings. A presentation will explain details about the program and registration documentation will be distributed. Representatives from the UF/IFAS Plant Improvement Team and the Florida Foundation Seed Producers Inc. also will be present. Citrus Extension agents are encouraged to attend.
Brown Dog Ticks

GAINESVILLE, Fla. – A little pest can really tick off dogs and their owners.
In addition to homeowners and canines, the pesticide industry has also been trying to find a way to vanquish the Brown Dog Tick for years.
But help is on the way, courtesy of University of Florida scientists.
Dogs and their owners who battle the Brown Dog Tick sometimes go to desperate measures ─ including getting rid of their dogs, fumigating their homes, throwing many possessions out or even moving ─ to control the pesky bugs, which breed indoors and hide in places that are practically impossible to reach.
Phil Kaufman, an associate professor of veterinary entomology at UF/IFAS, is one of several investigators who have just published two studies. One shows the tick is resistant to the most commonly used chemical applied directly between the dog’s shoulder blades. The other shows the effectiveness of carbon dioxide as a lure for baiting ticks to bed bug traps.
GAINESVILLE, Fla. — Though uncommon, Floridians can get tick diseases.
“The biggest myth about tick-borne diseases is that every tick carries the Lyme disease pathogen, when in fact, only one tick species in the Eastern U.S. is capable of transmitting the pathogen, Ixodes scapularis, the black-legged or deer tick,” said Phil Kaufman, a University of Florida veterinary entomologist.
Kaufman, an associate professor at the UF Institute of Food and Agricultural Sciences, cited three tick-borne diseases we should know about. Those diseases are:
- Lyme disease: In Florida, 673 cases of Lyme disease were reported from 2002 to 2011, according to the Florida Department of Health. That’s only 67 cases per year, compared to 27,000 cases in the U.S. in 2013. Of the Florida cases, 77 percent were acquired by people when traveling to other states.
- Rocky Mountain Spotted Fever: In Florida, the reported incidence has increased markedly in recent years, possibly due to increased disease awareness and reporting, Kaufman said. Some 163 cases of the fever were reported from 2002 through 2011, and 77 percent were acquired in Florida. Again, most were in north and central Florida. Cases of Rocky Mountain Spotted Fever are reported year-round, though peak transmission is typically during the summer.
- Ehrlichiosis (HME)/Anaplasmosis (HGE): In Florida, 89 cases of Ehrlichiosis/HME were reported from 2002 through 2011. Of those, 33 cases of Anaplasmosis/HGA were reported. The majority of HME cases – 73 percent — are reported as being acquired in Florida, primarily in the north and central parts of the state. Like Lyme disease, HGA has less than half — 45 percent — of cases classified as Florida-acquired.
GAINESVILLE, Fla. — A wasp the size of a pin head may control the nuisance Rugose spiraling whitefly, which leaves a sticky white mess that becomes covered in black mold on everything from plants to cars and pools, University of Florida scientists say.
“Although the Rugose spiraling whitefly damages plants, what really gets people worked up is that it’s a huge nuisance because it makes a mess,” said Catharine Mannion, an entomology professor at the UF/IFAS Tropical Research and Education Center in Homestead, Florida. “You get a sooty mold on everything. It’s hard to get pools cleaned. People start chopping their trees down.”
But a new breakthrough shows the tiny wasp encarsia noyesi reduces the population of the Rugose spiraling whitefly, according to a new UF/IFAS-led study funded by the Farm Bill, through the U.S. Department of Agriculture.
GAINESVILLE, Fla. — Have you always wanted to see what real, college-level, science research projects are like – and maybe even participate in one? Now is your chance with the University of Florida’s Institute of Food and Agricultural Sciences’ annual Bug Week.
Citizen science projects are a great way for kids of any age to help researchers in Florida – and throughout the country – understand what is taking place in their own neighborhoods. The projects can involve bug or animal counts, capturing specimens or creating habitats and reporting what shows up.
“Citizen science is a win-win for everyone involved,” said Andrea Lucky, an evolutionary biologist and biodiversity scientist with UF’s Department of Entomology and Nematology. “Participants have the opportunity to get involved in ongoing research and learn about the process of science and, at the same time, scientists benefit from partnering with diverse audiences.” (more …)
GAINESVILLE, Fla. — Two faculty members in the UF/IFAS Department of Agricultural and Biological Engineering have won prestigious global awards for outstanding contributions to their field.
One has also been elected to an advisory panel to the government of Spain.
Professor Rafael Muñoz-Carpena, has won the 2015 Hancor Soil and Water Engineering Award for “accomplishments in hydrological and integrated environmental modeling and education of next-generation soil and water scientists and engineers.”
Muñoz-Carpena, who specializes in hydrology and water quality, remembers when, as a doctoral student at North Carolina State University, his mentor, Wayne Skaggs, won the award. Skaggs later became a member of the National Academy of Sciences. Skaggs “is one of the fathers of modern agricultural drainage,” says Muñoz-Carpena.
The Hancor award means every bit as much to Muñoz-Carpena now.
“It has additional meaning to me,” he said, because his former mentor won the award. “It’s recognition of your work among peers. The fact that I got it surprises me.”
