GAINESVILLE, Fla. — The Royal Entomological Society has awarded its 2016 Best Paper Award to a paper written by University of Florida Institute of Food and Agricultural Sciences researchers. The paper was based on a study about a new way to monitor and trap a beetle that transmits a dangerous pathogen to certain trees.
Lukasz Stelinski, an associate professor of entomology at the UF/IFAS Citrus Research and Education Center, spearheaded the study in which investigators came up with a synthetic aroma to lure redbay ambrosia beetles into traps.
“Identifying an effective lure for the beetle is an important step in developing management tools for this pathogen-spreading insect in Florida,” Stelinksi said.
GAINESVILLE, Fla. — As we inch closer to summer and its inevitable rain, we also head toward mosquito egg-laying season. And as we do, Florida mosquito control officials may learn to emulate Pinellas County’s mosquito-borne disease surveillance program and its response to a West Nile virus outbreak in 2005, a University of Florida entomologist says.
“They have a top-notch mosquito surveillance program in Pinellas County,” said Professor Jonathan Day, a faculty member at the Florida Medical Entomology Laboratory, part of the UF Institute of Food and Agricultural Sciences. “That’s the model that we always go back to. They averted a much larger West Nile epidemic in 2005.”
Day will speak April 26 at the Southwest Regional Workshop on Arboviral Surveillance in Lehigh Acres, Florida. The workshop is organized by the Florida Mosquito Control Association and FMEL, and participants will analyze the 2011 and 2015 South Florida surveillance data regarding mosquito-borne viruses.
GAINESVILLE, Fla. — Florida’s citrus growers say as much as 90 percent of their acreage and 80 percent of their trees are infected by the deadly greening disease, which is making a huge dent in the state’s $10.7 billion citrus industry, a new University of Florida Institute of Food and Agricultural Sciences survey shows.
The survey, conducted in March 2015, shows the first grower-based estimates of both the level of citrus greening in Florida and the impact of greening on citrus operations in Florida.
“Even though the industry acknowledges that greening has reached epidemic proportions across the state, estimates of the level of infection and its impact on citrus operations are scarce,” the researchers wrote in the paper.
GAINESVILLE, Fla. — Whether it’s hybrid termites, grain pathogens, mosquito mating or something in between, University of Florida Institute of Food and Agricultural Sciences researchers are studying important topics and helping to solve global issues.
The UF/IFAS Research Dean’s Office recently recognized more than two dozen UF/IFAS faculty members for their impactful research, and Dean for Research Jackie Burns said she could not be more proud of the scientists.
“We recognize that these research articles are examples of the many published by UF/IFAS that are highly impactful and help reach solutions to worldwide issues including food shortages, nutrition, diseases and economic development,” Burns said. “Our faculty perform top-quality, globally-recognized scientific work, and we’re proud to recognize them.”
GAINESVILLE, Fla. — Just as the Zika virus is causing concern worldwide, a University of Florida insect specialist with 36 years of experience at the Florida Medical Entomology Laboratory has been named the lab’s new director.
Professor Jorge Rey started at FMEL, part of the UF Institute of Food and Agricultural Sciences, in 1979, the year the Vero Beach, Florida, lab came under UF’s umbrella. He moved up the faculty ranks from research scientist to professor in 1994 and was named interim director last year. Now, he’s the lab director, said Jack Payne, UF senior vice president for agriculture and natural resources.
“With his many years of top-quality research and his time as interim director of the Florida Medical Entomology Laboratory, Dr. Rey has earned the respect of the lab’s faculty members. Thus, he’s an ideal fit as director,” Payne said. “Dr. Rey is well-positioned to lead the FMEL scientists to new heights in research and Extension as we continue to look for solutions to mosquito-borne diseases such as dengue, chikungunya and Zika.”

GAINESVILLE, Fla. — Want to know how to differentiate between an Asian tiger mosquito and a yellow fever mosquito? Such knowledge may be worth your while because both mosquito species can transmit dangerous viruses such as chikungunya, dengue and zika if they bite you.
Students learn to identify mosquito species during a mosquito identification course being held now and in April at the Florida Medical Entomology Laboratory (FMEL), a Vero Beach facility and part of the University of Florida Institute of Food and Agricultural Sciences.
There are about 80 species in Florida; approximately 150 nationally and more than 3,500 globally, said Roxanne Connelly, a UF/IFAS Extension entomology professor and instructor for the courses. Connelly teaches identification of the adult mosquitoes, and Nathan Burkett-Cadena, an assistant professor at the UF/IFAS facility, teaches identification of larval mosquitoes.
GAINESVILLE, Fla. — Researchers with the University of Florida Institute of Food and Agricultural Sciences Plant Diagnostic Center will help shed light on potentially devastating plant diseases at the 4th National Meeting of the National Plant Diagnostic Network (NPDN) in Washington, D.C.
Held every three to four years, this year’s conference will take place March 8 to 12 in the nation’s capital.
Among those representing UF will be Jason Smith, a UF/IFAS associate professor of forest pathology. Smith’s topic is titled, “Holy Guacamole: Insights into the Emerging Laurel Wilt Pandemic.”
GAINESVILLE, Fla. — Figure this: Asian and Formosan subterranean termites cause about $32 billion in damage annually, worldwide, when you combine harm to structures and measures to control them. Now, University of Florida Institute of Food and Agricultural Sciences researchers predict these pests will dramatically increase their impact in the next two decades in South Florida and possibly across the nation.
In fact, UF/IFAS entomologists estimate subterranean termite activity will expand, meaning half the structures in South Florida will be at risk of infestation by subterranean termites by 2040.
Assistant Researcher Thomas Chouvenc, Distinguished Professor Nan-Yao Su and Professor Rudy Scheffrahn will publish their new study in June in the journal Florida Entomologist.
Six invasive termite species are now established in Florida, and among these, the Formosan subterranean termite, the Asian subterranean termite and the West Indian drywood termite pose particular concern for residents and the pest-control industry because they cause most of the structural damage.
GAINESVILLE, Fla. — With public concern about Zika, UF/IFAS Extension is giving tips on how to avoid contracting the virus.
Although the Zika virus is circulating in Central and South America and the Caribbean, currently, there is no evidence that local populations of Florida mosquitoes are infected. However, we need to be prepared and vigilant in case local transmission occurs, said Jorge Rey, professor and interim director of the Florida Medical Entomology Laboratory (FMEL), in Vero Beach Florida.
Roxanne Connelly, an Extension medical entomology specialist with FMEL, part of the University of Florida Institute of Food and Agricultural Sciences, says:
- People need to do all they can to manage the mosquitoes most likely to be involved in Zika virus transmission in Florida if the virus shows up in local mosquitoes. These mosquitoes are among those known as “container mosquitoes” specifically, the yellow fever mosquito, Aedes aegypti, and the Asian tiger mosquito, Aedes albopictus.
- Initial measures include getting rid of containers in your yard or outside your business, because they collect water and become perfect habitats for immature stages of these mosquito species. These include tires, wheel barrows, potted plants that sit on saucers, cans, bottles and more. You should inspect your yard weekly to make sure you don’t have any containers. Bromeliad plants and bird baths also can house container mosquitoes, Connelly said. For these types of mosquito habitats, they can be flushed with clean water weekly, or can be treated with mosquito-specific Bti granules (Mosquito Dunks or Mosquito Bits).
- Inspect windows and doors for hole and tears and repair them to exclude mosquitoes.
- Mosquito repellents should be used when people plan to be outdoors at the time mosquitoes are biting. The longest lasting repellents contain DEET and picaridin. Whatever type of repellant you use, read the label to make sure you’re putting on a product registered with the U.S. Environmental Protection Agency.

GAINESVILLE, Fla. — The lifting of an agricultural quarantine in Miami-Dade County on Feb. 13 signaled victory over the invasive Oriental fruit fly and a return to business as usual for growers within a 99 square-mile area that includes vegetable farms, nurseries, packing houses, residential neighborhoods and much of the state’s commercial tropical fruit acreage.
Officials with the University of Florida Institute of Food and Agricultural Sciences credit the success story to determination and teamwork by a partnership of growers, landscapers, homeowners, government officials and agency personnel, and UF/IFAS Extension faculty.
“Our personnel played a vital role in bringing the quarantine to a quick ending, by facilitating clear communication between producers and agency personnel,” said Jack Payne, UF senior vice president for agriculture and natural resources. “The good guys won, and we’re proud that we helped make it happen.”
Numerous UF/IFAS Extension faculty took part in a statewide effort known as the Oriental Fruit Fly Eradication Program, or OFF Program, he said. Funded and overseen by the Florida Department of Agriculture and Consumer Services (FDACS), the OFF Program also included representatives of the FDACS Division of Plant Industry, the U.S. Department of Agriculture Animal and Plant Health Inspection — Plant Protection Quarantine, the Miami-Dade County Agricultural Manager’s office, Miami-Dade County officials and growers’ organizations.
“Our faculty helped growers and regulators understand each other’s point of view,” Payne said. “Both sides were very motivated and once they recognized the need for cooperation, it wasn’t difficult to build consensus on a science-based plan to eradicate the fly.” Continue reading
