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. — 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. — 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.
GAINESVILLE, Fla. — The University of Florida Institute of Food and Agricultural Sciences has added another soldier in its battle against citrus greening by hiring world-renowned entomologist Bryony Bonning. She has been named Eminent Scholar with tenure in the UF/IFAS entomology and nematology department.
Currently, Bonning is a professor of entomology at Iowa State University and director of the National Science Foundation Center for Arthropod Management Technologies, where she oversees cutting-edge research on insect physiology and pathology, and biotechnology. Bonning is a recognized authority in the development of new technologies for insect pest management, and a fellow of the Entomological Society of America and the American Association for the Advancement of Science.
“Dr. Bonning brings an outstanding record of accomplishment and cooperation, and we are confident she will work tirelessly to develop solutions for citrus pest management,” said Blair Siegfried, chair of the UF/IFAS entomology and nematology department. “Her combined experience and achievements make her ideally suited and deserving of the position.”
GAINESVILLE, Fla. — If you are watching the Olympic games, you may catch students and alumni of the University of Florida. Seven of the 30 UF Gators who qualified to compete in the Rio Olympics are current or former students of the UF/IFAS College of Agricultural and Life Sciences.
“We are so proud of our students and alumni, who are not only representing the university and CALS, but also represent their home country at the world’s most elite competition,” said CALS Dean Elaine Turner.
QUINCY, Fla.— University of Florida Institute of Food and Agricultural Sciences Extension will host the Advanced Forest Site Prep Herbicide Workshop in Quincy, Florida to teach advanced techniques in herbicide applications.
The Advanced Forest Site Prep Herbicide Workshop is for natural resource managers who are responsible for site preparation decisions or implementation. The workshop will take place on July 13 from 9 a.m. to 2 p.m. at the UF/IFAS North Florida Research and Education Center.
This workshop will teach participants how to properly prepare a planting site for herbicide usage, review advanced technology in aerial application, different types of forestry surfactants and how herbicides work. There will also be a prescription process where experts will help participants diagnose a suitable herbicide program for the best vegetation management.
GAINESVILLE, Fla. — In a recent study, researchers with the University of Florida, Institute of Food and Agricultural Sciences in cooperation with Florida A&M University economists estimated that a 34-year program to control invasive pest mole crickets in the state has saved cattlemen approximately 13.6 million dollars a year. Over the long term, that figure balloons to 453 million dollars.
“The partnership with the State of Florida has been crucial to controlling the mole crickets,” said Norm Leppla, a UF/IFAS professor of entomology and nematology. “The Mole Cricket Biological Control Program has been worth every penny invested by the Florida Legislature and other stakeholders in the state.”
UF/IFAS researchers remember when the mole crickets reached outbreak levels in Florida during the mid-1900s and began wreaking hundreds of millions of dollars’ worth of damage to crops, pastures and turf. Cattlemen were beside themselves as they watched the tiny insects tear across their pastures like a biblical swarm of locusts. The effects were devastating, but not irreversible.

GAINESVILLE, Fla. – June is National Dairy Month and the University of Florida Institute of Food and Agricultural Sciences Dairy Unit is studying ways to get more milk and cheese to your table. But it’s no easy task to keep cows cool enough to produce in the scorching Florida sun.
That’s where researchers with the UF/IFAS Dairy Unit, in Hague, Florida come in. “It is difficult for a dairy cow in a hot environment to meet her full potential for either milk yield or fertility,” said Geoff Dahl, chair of the UF/IFAS animal sciences department. “The physiological adjustments the cow makes to prevent body temperature from rising during heat stress reduce productivity.”
This is especially true for cows in their dry period—cows in late pregnancy or who are not lactating. “These are times when we don’t milk the cows, because for six to eight weeks they don’t produce milk,” Dahl explained.
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers were honored for helping combat diseases affecting global agriculture, developing new plant varieties and conducting other impactful research and developments in the past year at the ninth annual UF/IFAS Florida Agricultural Experiment Station Research Awards ceremony.
