Redbay ambrosia beetles.
GAINESVILLE, Fla. — Using some pleasant-smelling chemicals, avocado growers may soon be able to repel beetles that inject a potentially deadly fungus into their trees, saving fruit and money, University of Florida Institute of Food and Agricultural Sciences researchers say.
When they’re infected with the laurel wilt fungus, redbay trees – a close cousin to the avocado — emit methyl salicylate to repel redbay ambrosia beetles, the very beetles that gave the trees the fungus in the first place, scientists say in a newly published study.
Florida avocados bring a $100 million-a-year impact to Florida’s economy, UF/IFAS economists say. They grow almost entirely in southern Miami-Dade County, but growers have battled the laurel wilt fungus, which can kill redbay and avocado trees, since it arrived in Georgia in 2003.

GAINESVILLE, Fla. — A few bugs may be able to chew up some cogongrass, a noxious weed that elbows out pasture grass, golf course greens and valuable ecosystems, a University of Florida Institute of Food and Agricultural Sciences researcher says.
A worldwide research team led by UF/IFAS entomology professor James Cuda and retired entomology professor Bill Overholt found species in Japan, East Africa and Indonesia that might help in the battle against cogongrass.
Among the arthropods they found, Cuda and his team discovered a midge from Indonesia that attacks cogongrass. Cuda and his team are focusing on the Orseolia javanica midge that causes cogongrass to produce linear galls at the expense of leaves. However, when scientists brought the arthropods back to the quarantine facility at the UF/IFAS Indian River Research and Education Center in Fort Pierce, Florida, they did not mate and increase in population.
FORT PIERCE, Fla.— Carey Minteer, a research professor with expertise in the use of biological controls to manage invasive plants, has joined the University of Florida Institute of Food and Agricultural Sciences. Florida has the most invasive species in the country, with 28 ports of entry, including seaports, airports and train stations.
Minteer, who is also an expert in geographic information systems, is based at the UF/IFAS Indian River Research and Education Center in Fort Pierce, Florida. She is collaborating with professor James Cuda, UF/IFAS Extension agent Ken Gioeli and other scientists to fight the state’s most noxious weeds, including the Brazilian peppertree, one of Florida’s most widespread invasive plants.
“Dr. Minteer has demonstrated effectiveness in investigating the biological control of invasive weeds in the central U.S.A. and Florida,” said Ronald Cave, UF/IFAS Indian River REC interim director. “Her expertise in biological control is strengthened with her knowledge of sophisticated mapping technology for spatial analysis of large infestations, thereby bringing a new dimension of research capability to the laboratory.”
FORT PIERCE, Fla. – Garima Kakkar is joining the University of Florida Institute of Food and Agricultural Sciences to help the state fight invasive pests. Kakkar, an expert in invasive insects, is a UF/IFAS Extension St. Lucie County Multicounty Agent.
Kakkar has a diverse range of experience in managing pest insects, and will now serve growers in the world’s premier citrus production region with the latest research findings. Her most recent assignment was working as a postdoctoral research associate for UF/IFAS, along with both UF and the U.S. Department of Agriculture in studies of an invasive whitefly, thrips vectors and a pepper whitefly.
“Dr. Kakkar has been synergistically blending research and practical information to create effective tools for the citrus and fruit crops industry,” said Ed Skvarch, director of UF/IFAS Extension St. Lucie County. “She believes that a channelized production system requires an Extension agent who is more than a liaison between different groups, researchers, growers or industry. Her goal is to develop programs that take research to the fields and industry, for the betterment of our agricultural production systems.”
Since taking her new position, Kakkar has focused on worker protection standards training, and she is organizing soil nutrition programs, developed in conjunction with the UF/IFAS Southwest Florida Research and Education Center in Immokalee, Florida, Skvarch said.

GAINESVILLE, Fla. — A University of Florida Institute of Food and Agricultural Sciences entomologist will use a $200,000 grant from the Florida Department of Health to improve tests for the detection of Zika virus.
In 2016, Florida saw 1,272 cases of Zika, which is usually associated with mild symptoms, although severe symptoms may also occur, including Guillain-Barré syndrome and birth defects in babies, according to the U.S. Centers for Disease Control and Prevention. Of those, 256 were locally acquired. So far this year, four more cases have been reported, all travel-related.
Barry Alto, a UF/IFAS assistant professor of medical entomology, said scientists need better diagnostic tools to detect Zika virus to meet challenges to public health. He is working with collaborator Steven Benner at Firebird Biomolecular Sciences LLC to develop methods they hope should take about an hour – far less time than current testing methods. Existing methods require specialized equipment and highly trained personnel, so samples must be transported to specialized laboratory facilities to perform the tests.
GAINESVILLE, Fla. — Facial recognition software is no longer a thing of the future. But what if similar technologies could one day help farmers identify pests in the field?
Steve Futch, multi-county citrus agent with the University of Florida Institute of Food and Agricultural Sciences Extension, thinks it’s possible. And thanks to the new UF/IFAS Extension Entrepreneurship Program, he and other UF/IFAS Extension faculty now have more of the tools they need to make their ideas a reality.
“One of the missions of UF/IFAS Extension is to connect Floridians with science-based information that will improve their quality of life. Our relationships with our clientele are always evolving, so we are always reassessing and rethinking how we can better serve our audience,” said Nick Place, dean for UF/IFAS Extension. “Entrepreneurial thinking can help us get out of our comfort zone and approach problems in new and creative ways.”
Jan. 17 to 19, UF/IFAS Extension faculty members from around the state heard presentations from several UF entrepreneurship experts, including Elio Chiarelli, entrepreneurship specialist with the UF/IFAS Center for Leadership. As a doctoral student in the UF department of agricultural education and communication, Chiarelli’s research focused on successful entrepreneurship within agriculture and natural resources.
GAINESVILLE, Fla. — Nearly a century ago, a group of Polk County citrus growers raised about $14,000 to buy land for a research station. Now, the University of Florida Institute of Food and Agricultural Sciences will celebrate the 100th anniversary of the UF/IFAS Citrus Research and Education Center.
In 1917, UF/IFAS established the Citrus REC. Originally, only a few UF/IFAS scientists worked at the Lake Alfred site, then called the Citrus Experiment Station.
Today, the research center employs 250 people and is also home to the scientific research staff of the Florida Department of Citrus. It is the largest facility in the world devoted to a single commodity, citrus.
“The UF/IFAS Citrus REC has a long, proud tradition of outstanding science and outreach, and the faculty there show every day why the quality of work performed for the next 100 years will be as good or better than the first century at the facility,” said Jack Payne, senior vice president for agriculture and natural resources.
FORT PIERCE, Fla. – Rhuanito “Johnny” Soranz Ferrarezi has joined the University of Florida Institute of Food and Agricultural Sciences to lead citrus horticulture research in the world’s premier grapefruit production region.
Ferrarezi brings more than 10 years of experience to his new position as assistant professor of citrus horticulture to the UF/IFAS Indian River Research and Education Center in Fort Pierce. He joins two additional new hires at UF/IFAS IRREC who will work as a team to assist growers as they manage citrus greening, or Huanglongbing (HLB), the industry’s most formidable pathogen.
“Dr. Ferrarezi is capable and exuberant about his work to manage crop production,” said Ronald Cave, UF/IFAS IRREC director. “He has demonstrated a fervent commitment to agriculture in his native Brazil, which is also one of the world’s most productive citrus regions, and we are confident his work in Florida will be significant.”
FORT LAUDERDALE, Fla. — The University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) and the Florida Fish and Wildlife Conservation Commission (FWC) are working together on unique projects to target Burmese pythons in Florida. Two projects include using detection dogs and Irula tribesmen to help remove pythons from environmentally sensitive areas.
In their first eight days on the job, the Irula tribesmen — world-renowned snake catchers from India — removed 13 pythons, including four on their first visit to Crocodile Lake National Wildlife Refuge on North Key Largo in partnership with the U.S. Fish and Wildlife Service. Traditionally, the main occupation of the Irula tribe has been catching snakes. They have successfully hunted and captured Indian pythons in their home province of Tamil Nadu.
“Since the Irula have been so successful in their homeland at removing pythons, we are hoping they can teach people in Florida some of these skills,” said Kristen Sommers, section leader of the FWC’s Wildlife Impact Management Section. “We are working with our partners to improve our ability to find and capture pythons in the wild. These projects are two of several new efforts focused on the removal of these snakes.”
GAINESVILLE, Fla. — A trio of projects aimed at helping Florida producers cope with the bacterial disease known as citrus greening topped the list of stories shared by the University of Florida Institute of Food and Agricultural Sciences in 2016.
This year marked the beginning of the state’s second decade battling greening disease, which is also known as Huanglongbing or HLB. Other top stories for the year involved invasive organisms causing negative impacts to Florida’s economy and environment, and even the health of its residents.
