GAINESVILLE, Fla. — Two University of Florida Institute of Food and Agricultural Sciences faculty in the food and resource economics department have each been selected for UF/IFAS Extension Professional and Enhancement awards. These awards highlight exceptional UF/IFAS Extension programming, and earn faculty additional funding and program support.
Tatiana Borisova, associate professor and Extension specialist, has been selected for the Wells Fargo Extension Professional Award and Program Enhancement Grant, which recognizes a proposed educational program that responds to a public policy issue.
Borisova, who specializes in water economics and policy, is interested in educating Floridians about water resource management.
“In recent years, changes to water resource laws and regulations have rapidly accelerated in Florida and the U.S.,” said Borisova. “Meanwhile, public knowledge of water laws and regulations is limited. Public participation is vital for development and implementation of water resource management programs.”
BELLE GLADE, Fla. — Want to teach your students the good, the bad and the ugly about plants while incorporating three different sciences? Researchers at the UF/IFAS Everglades Research and Education Center will lead the second annual workshop, “Don’t Get Caught with Your Plants Down,” from 8:30 a.m. to 3 p.m. on Tuesday, Sept. 27.
The free workshop will be held at UF/IFAS Everglades Research and Education Center, 3200 East Canal Street, Belle Glade, Florida. Breakfast and lunch will be provided, and in-service points for professional development will be awarded by school districts through Master Inservice Plans (MIP).
This year’s program, developed by the UF/IFAS department of plant pathology, uses resources available from the American Phytopathological Society, said Richard Raid, a professor of plant pathology and workshop organizer. Middle and high school teachers will take back vital information to students on the importance of plants in daily life, he said.
Florida is home to the most invasive species in the country, and many travel in to the state via plants, Raid explained.
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. — Florida beekeepers are concerned after 2.5 million bees that were killed during an aerial spraying with Naled/Dibrom for Zika-carrying mosquitoes in Dorchester County, S.C. Now, Floridians are looking for ways to avoid the same tragedy. Florida is the third-largest beekeeping state in the nation.
Researchers are not surprised that the South Carolina incident has Florida beekeepers worried, said Fred Fishel, professor of agronomy and director of the Pesticide Information Office.
“With the Zika cases in south Florida, and now that scientists have identified mosquitoes that carry the Zika virus, we would expect beekeepers to be concerned about increased pesticide application,” Fishel said. “But, registered beekeepers should be notified before an application of pesticides. That gives them time to protect their bees while spraying is conducted.”
There are pesticides that will not harm bees, but will kill mosquitoes, says William Kern, associate professor of urban entomology at the UF/IFAS Fort Lauderdale Research and Education Center.
GAINESVILLE, Fla. — Researchers with the University of Florida Institute of Food and Agricultural Sciences are closer to helping producers better meet global food demand, now that they’ve combined simulation and statistical methods to help them predict how temperature affects wheat crops worldwide.
A global team of scientists, led by those at UF/IFAS, used two different simulation methods and one statistical method to predict the impact of rising temperatures on global wheat production, and all came to similar estimates.
This finding, published in a study in the journal Nature Climate Change, is critical in predicting how much wheat and other crops we’ll need to feed the world, said Senthold Asseng, a UF/IFAS professor of agricultural and biological engineering and leader of this study.

GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers have found a better way to assess the potential impacts of low dose mixtures of man-made chemicals — like pharmaceuticals and personal care products — on water bodies and their ecosystems.
Such products – known to scientists as PPCPs – are widely released into the world’s freshwaters and oceans, where they mix at low concentrations over long time periods and seep into diverse environmental pathways such as surface water, groundwater, drinking water or soil.
“The end effect could be degradation of aquatic life,” said Rafael Muñoz-Carpena, a UF/IFAS professor of agricultural and biological engineering and a lead author of a new UF/IFAS-led study. “Some pharmaceuticals that individually are typically not toxic at even high doses, can damage aquatic life at very low doses when present in complex mixtures often found in natural waters after wastewater finds its way there.”

GAINESVILLE, Fla. — Hops research by University of Florida Institute of Food and Agricultural Sciences researchers is gaining national scientific recognition in addition to media attention.
Three UF/IFAS scientists are not only trying to see if hops will grow in Florida’s hot, humid climate, but they also want to know whether they can quench the thirst of the fast-growing micro-brewing industry.
Brian Pearson, a UF/IFAS assistant professor of environmental horticulture, is one of three members of the hops research team. Pearson’s research to date won him third place in the Early Career Award for scientists at the American Society of Horticultural Sciences (ASHS) in early August. The Early Career Competition is for new faculty and professionals to share their discoveries to a peer audience.
“This is just the beginning of our alternative and specialty crop research,” said Pearson, a faculty member at the UF/IFAS Mid-Florida Research and Education Center in Apopka, Florida. “Working with hops, fennel, safflower and skullcap, we hope to bring an array of viable, high-value alternative crops to Florida growers.”
GAINESVILLE, Fla. — Researchers with the University of Florida Institute of Food and Agricultural Sciences are working to find a cure or develop resistant varieties for a virus that is attacking sugarcane and sorghum throughout the Everglades agricultural region. Florida produces more than 50 percent of all sugarcane in the United States, making it the largest producer in the nation.
The sugarcane yellow leaf virus was first identified in Hawaii during the 1980s. The virus was found in Florida in 1993, said Philippe Rott, a professor of plant pathology at the UF/IFAS Everglades Research and Education Center in Belle Glade, Florida. Symptoms include a yellow stripe down the middle of sugarcane leaves, he said.
“The virus travels down the vascular bundle of the plant and interferes with the movement of nutrients,” Rott said. “This, in turn, stunts the growth of the plant.”
The virus is carried by an aphid, a tiny bug that feeds by sucking sap from plants, said Gregg Nuessly, director of UF/IFAS Everglades REC and a professor of entomology. Nuessly’s and Rott’s research has identified the carrier of the virus, and trials are in progress to see if insecticides are effective at killing the aphid.
