GAINESVILLE, Fla. – A little pest can really tick off dogs and their owners.
In addition to homeowners and canines, the pesticide industry has also been trying to find a way to vanquish the Brown Dog Tick for years.
But help is on the way, courtesy of University of Florida scientists.
Dogs and their owners who battle the Brown Dog Tick sometimes go to desperate measures ─ including getting rid of their dogs, fumigating their homes, throwing many possessions out or even moving ─ to control the pesky bugs, which breed indoors and hide in places that are practically impossible to reach.
Phil Kaufman, an associate professor of veterinary entomology at UF/IFAS, is one of several investigators who have just published two studies. One shows the tick is resistant to the most commonly used chemical applied directly between the dog’s shoulder blades. The other shows the effectiveness of carbon dioxide as a lure for baiting ticks to bed bug traps.
GAINESVILLE, Fla. — A wasp the size of a pin head may control the nuisance Rugose spiraling whitefly, which leaves a sticky white mess that becomes covered in black mold on everything from plants to cars and pools, University of Florida scientists say.
“Although the Rugose spiraling whitefly damages plants, what really gets people worked up is that it’s a huge nuisance because it makes a mess,” said Catharine Mannion, an entomology professor at the UF/IFAS Tropical Research and Education Center in Homestead, Florida. “You get a sooty mold on everything. It’s hard to get pools cleaned. People start chopping their trees down.”
But a new breakthrough shows the tiny wasp encarsia noyesi reduces the population of the Rugose spiraling whitefly, according to a new UF/IFAS-led study funded by the Farm Bill, through the U.S. Department of Agriculture.
GAINESVILLE, Fla. — Have you always wanted to see what real, college-level, science research projects are like – and maybe even participate in one? Now is your chance with the University of Florida’s Institute of Food and Agricultural Sciences’ annual Bug Week.
Citizen science projects are a great way for kids of any age to help researchers in Florida – and throughout the country – understand what is taking place in their own neighborhoods. The projects can involve bug or animal counts, capturing specimens or creating habitats and reporting what shows up.
“Citizen science is a win-win for everyone involved,” said Andrea Lucky, an evolutionary biologist and biodiversity scientist with UF’s Department of Entomology and Nematology. “Participants have the opportunity to get involved in ongoing research and learn about the process of science and, at the same time, scientists benefit from partnering with diverse audiences.” (more …)
GAINESVILLE, Fla. — Two faculty members in the UF/IFAS Department of Agricultural and Biological Engineering have won prestigious global awards for outstanding contributions to their field.
One has also been elected to an advisory panel to the government of Spain.
Professor Rafael Muñoz-Carpena, has won the 2015 Hancor Soil and Water Engineering Award for “accomplishments in hydrological and integrated environmental modeling and education of next-generation soil and water scientists and engineers.”
Muñoz-Carpena, who specializes in hydrology and water quality, remembers when, as a doctoral student at North Carolina State University, his mentor, Wayne Skaggs, won the award. Skaggs later became a member of the National Academy of Sciences. Skaggs “is one of the fathers of modern agricultural drainage,” says Muñoz-Carpena.
The Hancor award means every bit as much to Muñoz-Carpena now.
“It has additional meaning to me,” he said, because his former mentor won the award. “It’s recognition of your work among peers. The fact that I got it surprises me.”
GAINESVILLE, Fla. — The University of Florida campus is aflutter with activity as it gears up for Bug Week 2015, with various online and campus activities for students of all ages and their families.
“Bugs are serious business in Florida,” said Jack Payne, UF senior vice president for agriculture and natural resources. “Learning about bugs, though, should be fun. That’s why we have Bug Week.”
Bug Week 2015 is scheduled for May 18-23. To get started, check out the Bug Week website at http://bugs.ufl.edu/. UF/IFAS has a number of online resources there to explore including bug photos, feature stories, and the popular “Bug of the Day” and “Bug Word of the Day” items. Citizen science projects – in which anyone can participate – are spotlighted on the website, along with videos about everything from ants and butterflies to spiders and ticks. (more …)
GAINESVILLE, Fla. — Invasive stiltgrass is bad enough by itself, crowding out native plant and insect species in about 25 eastern U.S. states, including Florida. It can also inhibit tree seedling survival and growth, and it can change the availability of nitrogen in the soil.
In general, invasions of non-native plant species can reduce biodiversity and alter ecosystems. In 2013, 1,585 prescribed fires were used to burn about 290,000 acres in eight eastern U.S. states. Scientists have used prescribed fires to effectively control some invasive plants, but new evidence suggests fires may promote stiltgrass invasions.
If land managers perform prescribed fires — normally used to manage ecosystems and prevent wildfires – in stiltgrass-invaded areas, native trees can be killed by the more intense fires caused by burning stiltgrass, said Luke Flory, an assistant professor of ecology at the University of Florida Institute of Food and Agricultural Sciences.
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences faculty have developed a new app for avocado growers that provides an irrigation schedule so users save an estimated 20 to 50 percent on the water they apply to their orchards.
“Weather changes daily, and the app takes into account these changes in the irrigation schedule it provides,” said Kati Migliaccio, an associate professor in agricultural and biological engineering at UF’s Tropical Research and Education Center in Homestead, Florida.
The Alaska salmon fishery is touted as one of the best in the world. When measured with an ecological yardstick, it is – fish stocks are healthy and the fishery is certified by the Marine Stewardship Council as consistently meeting rigorous biological standards. Fish are individually counted as they swim upstream to ensure there are enough to breed.
But Alaska salmon falls behind some of the world’s fisheries in how it benefits local fishermen, processing workers and nearby rural communities, according to a new assessment that ranks the vitality of a fishery by looking at its economic and community benefits as well as its ecological health.
“We wanted to develop a new set of metrics to determine how well fisheries management systems work and to test what factors are most effective in improving them,” said James Anderson, professor of Food and Resource Economics and director of the new Institute for Sustainable Food Systems at the University of Florida Institute of Food and Agricultural Sciences. Anderson is a lead author of a paper published May 6 in the journal PLOS ONE, describing the new methodology.
“These new Fishery Performance Indicators (FPIs) are designed to help us evaluate a fishery system’s performance toward achieving economic, community and ecological sustainability – the ‘triple bottom line,'” he said.

GAINESVILLE, Fla. — Deep in the soil, underneath your pretty trees, shrubs, plants and vegetables, lurks a fungus lethal to all of them. But University of Florida plant pathologist G. Shad Ali has a tiny silver bullet to kill it.
Ali and a team of researchers with UF’s Institute of Food and Agricultural Sciences, along with the University of Central Florida and the New Jersey Institute of Technology, have found that silver nanoparticles produced with an extract of wormwood, can stop several strains of the fungus phytophthora dead in its tracks.
Phytophthora attacks the leaves and roots of more than 400 plants and tree varieties – everything from tomato plants to oak trees – threatening the Florida’s $15 billion-a-year ornamental horticulture industry.
“The silver nanoparticles are extremely effective in eliminating the fungus in all stages of its life cycle,” Ali said. “In addition, it had no adverse effects on plant growth.”
