GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers will introduce genetic biotechnology as a potential means to preserve forests at a national conference next week in Washington, D.C.
Jiri Hulcr, an assistant professor in the UF/IFAS School of Forest Resources and Conservation, and one of his doctoral students, Caroline Storer, will host the symposium at the North American Forest Insect Work Conference May 31 to June 3.
Hulcr sees this conference as an opportunity for the UF/IFAS forest entomology team to disseminate innovative solutions to maintain tree health.
“Exploring the use of biotechnology in tree health protection is important to us, because we are increasingly running out of other options,” Hulcr said.
Additionally, he said: “Trees and forests provide jobs and benefits for everyone. Yet, around city neighborhoods and rural forests, anyone can witness the diminishing health of trees. The culprit is exotic pests and diseases. Forget pollution or drought: It is destructive tree diseases and pests — imported by overseas travelers or business people — that are nearly eliminating some tree species from our forests and orchards.”
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.
“Our researchers don’t think the sky is falling; they believe that the sky is the limit,” said Jackie Burns, dean for UF/IFAS Research. “It is a privilege to be associated with faculty who are the best and brightest.”
Awards were given for the best thesis and dissertation from master’s and Ph.D. students in the College of Agricultural and Life Sciences. Honors were also bestowed to the UF/IFAS 2015 University of Florida Research Foundation Professors, researchers who produced outstanding publications and those who developed new plant and utility patents. Some of the patents included a highly rated variety of tomato called “Garden Gem,” six new varieties of the Coleus plant, including “Gator Glory,” and an invention to control flies and mosquitoes.
GAINESVILLE, Fla. — People in Palm Beach County can help manage a potential outbreak of the Q-biotype whitefly through early detection and identification of the insect, a University of Florida Institute of Food and Agricultural Sciences researcher says.
This significant tropical and subtropical pest may threaten Florida crops such as tomatoes, squash, beans, watermelons and many other vegetables and ornamentals if immediate measures are not taken to prevent its spread. Known scientifically as Bemisia tabaci, the Q-biotype is a light-colored, flying insect slightly less than 1 millimeter in length. Thus far, the Q-biotype whitefly has been reported in all four quadrants of Palm Beach County – north, east, south and west – said Lance Osborne, a UF/IFAS entomology professor.
To find and detect this whitely, residents should first look at hibiscus plants because those are host plants to which this whitefly species will likely gravitate. They should also take a look at their poinsettia plants, Osborne said. There are two types of this whitefly species: Q-biotype and B-biotype, and they look virtually the same, so it’s critical to get a genetic analysis to determine if you have the Q-biotype whitefly.

GAINESVILLE, Fla. — Heat from city sidewalks, streets, and parking lots, along with insect pests, can damage trees planted in urban landscapes. Thus, it is critical to plant trees in the right places so they will do well in harsh urban environments, a University of Florida Institute of Food and Agricultural Sciences researcher says.
More than half the world’s people and 80 percent of the U.S. population live in urban areas. Trees benefit these residents by filtering the air, reducing temperatures and beautifying landscapes. According to a new study led by Adam Dale, a UF/IFAS assistant professor of entomology, these benefits are reduced when trees are planted in unsuitable urban landscapes. However, guidelines can be developed to lead urban tree- planting decisions in a more sustainable direction.
Dale spearheaded the study while at North Carolina State University in Raleigh, North Carolina. Previous research by Dale and his colleagues found that impervious surfaces raise temperatures, which increase pest abundance and tree stress, ultimately reducing tree health. He and his team examined the so-called “gloomy scale insect,” which feeds on tree sap and appears as small bumps on the bark of trees.
GAINESVILLE, Fla. — The Q-biotype whitefly, a significant tropical and subtropical pest, may threaten Florida crops such as tomatoes, squash, beans, watermelons and many other vegetables and ornamentals if immediate measures are not taken to prevent its spread.
Scientists statewide, including those with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), are working together to control the whitefly which, for the first time, has been found outside greenhouses and nurseries in Florida. Known scientifically as Bemisia tabaci, the Q-biotype or Mediterranean whitefly is a light-colored, flying insect slightly less than 1 millimeter in length.
Researchers with UF/IFAS are working with the U.S. Department of Agriculture, Agricultural Research Service and the Florida Department of Agriculture and Consumer Services to manage the whitefly.
“Unfortunately, we have a developing whitefly issue in Florida,” said Lance Osborne, a faculty member at the UF/IFAS Mid-Florida Research and Education Center in Apopka, Florida. “The situation may be improved with diligent attention to identifying and reporting any outbreaks.”

GAINESVILLE, Fla. — When Kenny Coogan, a seventh-grade science teacher at Orange Grove Middle Magnet School, took an airboat ride on Lake Tohopekaliga and saw the devastation caused by invasive plants, he knew he had to bring this information back to his classroom.
“After seeing the negative effects of the plants first-hand, I knew I needed to share this experience and ways to mitigate the invasive species with my students,” Coogan said.
Local middle and high school science teachers like Coogan are getting help in spreading the word about invasive plants, thanks to a partnership between the University of Florida Institute of Food and Agricultural Sciences and Florida Fish and Wildlife Conservation Commission.
Each June the UF/IFAS Center for Aquatic and Invasive Plants invites 24 teachers from across the state to a five-day Plant Camp where they learn about invasive plants and how they can bring this knowledge and awareness into the classroom.
GAINESVILLE, Fla. — While consumers are aware of genetically modified crops and food, their knowledge level is limited and often at odds with the facts, according to a newly published study by a University of Florida researcher.
Last year, Brandon McFadden, an assistant professor of food and resource economics at the UF Institute of Food and Agricultural Sciences, published a study that showed scientific facts scarcely change consumers’ impressions of genetically modified food and other organisms.
Consumer polls are often cited in policy debates about genetically modified food labeling. This is especially true when discussing whether food that is genetically modified should carry mandatory labels, McFadden said. In conducting their current study, McFadden and his colleague, Jayson Lusk, an agricultural economics professor at Oklahoma State University, wanted to know what data supported consumers’ beliefs about genetically modified food and gain a better understanding of preferences for a mandatory label.
So he conducted the survey to better understand what consumers know about biotechnology, breeding techniques and label preferences for GM foods.
GAINESVILLE, Fla. — Homemade do-it-yourself remedies found online and circulated on social media should be regarded with cautious skepticism unless there is UF-based research supporting the product, according to researchers at the University of Florida Institute of Food and Agricultural Sciences.
For example, there is no scientific evidence that eating garlic, vitamins, onions or any other food will make a person less attractive to host-seeking mosquitoes, UF/IFAS experts said.
UF/IFAS conducts research and extension on mosquito repellents, said Ken Gioeli, program Extension agent for natural resources and the environment for UF/IFAS Extension St. Lucie County.
APOPKA, Fla. — If you’re browsing plants in a nursery or home-improvement store, labels such as “pollinator friendly” will likely influence which plants you end up buying, according to a recent study by University of Florida Institute of Food and Agricultural Sciences researchers.
Postdoctoral research associate Alicia Rihn and assistant professor Hayk Khachatryan co-authored the study, which appears in the journal HortScience. Both Rihn and Khachatryan are researchers in the UF/IFAS food and resource economics department at the UF/IFAS Mid-Florida Research and Education center in Apopka, Florida.
Rihn and Khachatryan wanted to know how labels such as “pollinator friendly” would influence consumer attitudes. “We wondered, which pollinator insect related labels are the most effective and which do consumers prefer?” Khachatryan said. “At the time of our study, these topics had not been addressed.”
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.
