GAINESVILLE, Fla. — Agriculture and natural resources interests are invited to come home to the University of Florida Institute of Food and Agricultural Sciences and see some informative exhibits during Agriculture and Gardening Day Oct. 15, outside The Swamp.
“Come home” because it’s homecoming weekend at UF, and the Gators are playing the Missouri Tigers. People affiliated with agriculture and natural resources have bought discounted tickets to the football game.
Before kickoff, those parties can view a display from UF/IFAS, which will feature information about the organization’s three arms: education, research and Extension.
There will also be displays from the UF/IFAS entomology and nematology department, said Ruth Borger, UF/IFAS assistant vice president for communications. Those exhibits include a bug zoo at which you can pet a roach, if that tickles your fancy. The department also will bring microscopes so you can view nematodes.

GAINESVILLE, Fla. — Trees shade our homes and help clean the air of our cities. However, their production in the nursery and maintenance in the landscape requires energy and material resources. Some of those processes are mechanized and release greenhouse gases like carbon dioxide.
Understanding this balance between tree environmental costs and benefits is crucial to those who plan and plant urban forests as it can help inform species selection, site development and prescribed care measures, says a University of Florida Institute of Food and Agricultural Sciences researcher and UF/IFAS Extension specialist.
In addition to providing shade, trees take in carbon dioxide – a greenhouse gas – and convert it and store it as carbon in their woody tissues. Trees generally provide the greatest environmental and economic benefits as they mature and grow to a significant size, said UF/IFAS environmental horticulture assistant professor Andrew Koeser.
In a newly published study, Koeser and Aaron Petri of the University of Illinois used a concept called “carbon neutrality” to examine tree benefits. When trees start storing more carbon than they emit – offsetting the amount spent by nurseries and foresters in tree care, that’s called “carbon neutrality.” That care can include planting, water, pest control, mulching, pruning and more.
“In general, the bigger the tree, the more environmental benefits you receive. Over time, the benefits of a tree finally equal its associated costs, with regard to carbon balance,” Koeser said. “I like to think of this as the tree paying back the environmental debt. If the tree doesn’t get to this point, it is emitting more carbon dioxide than it’s taking in and does a disservice to the environment.”

GAINESVILLE, Fla. — Growers in Florida’s $300 million-a-year strawberry industry now have proof that the latest UF/IFAS-bred variety lasts longer on the shelf and tastes sweeter than two UF/IFAS cultivars, making it more attractive to faraway markets.
“These two attributes together make for a clear step up in eating quality for the consumer,” said Vance Whitaker, an associate professor of horticultural sciences and strawberry breeder at the UF/IFAS Gulf Coast Research and Education Center in Balm, Florida.
In a newly published study, scientists studied traits for Sweet Sensation® ‘Florida127,’ which was released commercially in the 2014-2015 growing season. Researchers compared them to those of ‘Florida Radiance’ and ‘Strawberry Festival,’ two other UF/IFAS-bred varieties.

GAINESVILLE, Fla. — About 1.56 million people worked full- or part-time in agriculture, natural resources and food industries in 2014, an increase of about 40,000 workers from 2013, and nearly 29 percent from 2001, according to a new University of Florida Institute of Food and Agricultural Sciences economic report.
Direct employment in the agriculture and natural resources sectors accounted for 13.8 percent of all jobs statewide. Employment in these sectors grew from 1.24 million jobs in 2001 to a peak of 1.34 million in 2008 before the recession, then recovered to 1.56 million in 2014, the latest year for which information is available.
“I would characterize that as modest growth in the industry, although the growth rate was higher before and after the recession (before 2007 and after 2010), and ag-food fared much better during the recession than many other leading industries such as construction and tourism,” said Alan Hodges, Extension scientist with the UF/IFAS food and resource economics department. “Growth in economic activity of agriculture, natural resources and related food industries continues to contribute to the stability of the state’s economy.”
GAINESVILLE, Fla. — Through a curriculum appropriately titled, “Bed Bugs and Book Bags,” students worldwide are learning how to identify bed bugs, where they hide out and much more. The program teaches how to prevent the insects, and a new University of Florida Institute of Food and Agricultural Sciences study shows the hands-on learning experience works.
The project started in 2012 in Duval County Public Schools and teaches the public how to know if the insect is indeed a bed bug and then how to deal with it. As measured by students’ increased knowledge of bed bugs, the curriculum succeeds in the United State, Canada, Israel and Saudi Arabia, the study shows.
Public knowledge of bed bugs is critical because the insects are coming back.
“Within the past few years, bed bug infestations have dramatically increased and have created major concern for society and for pest management professionals,” said Roberto Pereira, a UF/IFAS associate research scientist in entomology and a lead author on the new study. “They are thought to be the most difficult and expensive insect pests to control in the United States. By being aware of signs of infestation in our daily activities, we all can play our part to prevent spreading these pests.”

GAINESVILLE, Fla. — The University of Florida Institute of Food and Agricultural Sciences, the UF College of Liberal Arts and Sciences, and Santa Fe College have teamed up to manage the Seahorse Key Marine Laboratory, an off-shore facility in the Cedar Keys National Wildlife Refuge.
“This collaboration across our campus and between UF and Santa Fe College will increase our capacity for research, Extension and teaching on the Nature Coast,” said Micheal Allen, director of the UF/IFAS Nature Coast Biological Station, a research unit located in Cedar Key, Florida. “Our combined efforts will enhance UF’s impact on the local community and its natural resources.”
Seahorse Key is home to a laboratory, marine specimen collection and a pre-Civil War era lighthouse, which has a bunkhouse with 26 beds for overnight stays. The island is also a field site for snake and bird research, Allen said.
GAINESVILLE, Fla. — A recent study led by a University of Florida Institute of Food and Agricultural Sciences researcher found that an insect has evolved metabolically in response to an increase in weather cold snaps.
Daniel Hahn, an associate professor in the entomology and nematology department at UF/IFAS, led a team of researchers from UF, the University of California Berkeley, the University of Alabama-Birmingham and Kansas State University in the study of the fly, Drosophila melanogaster. Researchers found that selection to recover more quickly from cold snaps also drove the evolution of higher metabolic rates.
“While we hear a lot about warmer weather in spring and fall, weather fronts will continue to bring bouts of cold,” said Hahn, whose research focuses on ecological and evolutionary physiology. “This makes the transitions from warm to cold temperatures more extreme, and increases the vulnerability of animals and plants to damage from snap freezes.
“Small animals that rely on the environment to regulate their body temperature—like insects, frogs, and even sea turtles—are also susceptible to stress and even death from extreme cold fronts. We found clear changes in metabolism of the fly as it evolves and adapts to the cold snaps.”

GAINESVILLE, Fla. — As researchers nationwide try to get college students to eat healthier foods, they’re finding that gardening may lead to a lasting habit of eating more fruits and vegetables.
That’s a recent conclusion from the “Get Fruved” project. “Get Fruved,” an acronym for “Get Your Fruits and Vegetables,” is a $4.9 million collaborative project among eight American universities, including the University of Florida. At UF, the Institute of Food and Agricultural Sciences is leading the campus study. One of the first steps of the project is to better understand what factors predict and influence the health behaviors of college and high school students.
A new study from Get Fruved shows if college students gardened as a child or use their green thumbs now, chances are they will eat more fruits and vegetables than those who don’t.
“This finding is particularly relevant, given the recent popularity of school gardens and farm-to-school projects,” said Anne Mathews, a UF/IFAS assistant professor of food science and human nutrition and lead author of the study.
GAINESVILLE, Fla. — People with too much iron in their bodies can develop serious illnesses. So University of Florida Institute of Food and Agricultural Sciences researcher James Collins plans to use a $2.5 million grant to begin to regulate iron absorption in the intestines.
Intestinal iron absorption is important because humans have no way to excrete excess iron. This inability to get rid of excess iron can create a condition known as “iron overload.” It can lead to cardiac issues, cancer, diabetes and a slew of other illnesses, Collins said.
People with genetic iron-overload disorders, or hemochromatosis, could eventually benefit from the research that Collins and his team will conduct.
GAINESVILLE, Fla. — The University of Florida Institute of Food and Agricultural Sciences tackled many issues, including battling citrus greening, developing improved turfgrass and crops as well as combatting agricultural pests with a record $140 million in the 2015-2016 fiscal year, an 11 percent increase over the previous year.
UF/IFAS received $125.8 million for research in 2014-2015.
The $140 million is part of $724 million in research funding received by UF. The funding came from federal agencies, foundations, state agencies, local and regional government, companies and other sources.
Of the research money, UF/IFAS received about $24 million in external funds for citrus research.
Also, major U.S. Department of Agriculture grants to UF/IFAS included $4.4 million to develop improved turfgrass; $3.4 million to try to stem the impact of laurel wilt on avocados and $3.4 million to combat a bacterial disease damaging tomatoes.
