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. — Though uncommon, Floridians can get tick diseases.
“The biggest myth about tick-borne diseases is that every tick carries the Lyme disease pathogen, when in fact, only one tick species in the Eastern U.S. is capable of transmitting the pathogen, Ixodes scapularis, the black-legged or deer tick,” said Phil Kaufman, a University of Florida veterinary entomologist.
Kaufman, an associate professor at the UF Institute of Food and Agricultural Sciences, cited three tick-borne diseases we should know about. Those diseases are:
- Lyme disease: In Florida, 673 cases of Lyme disease were reported from 2002 to 2011, according to the Florida Department of Health. That’s only 67 cases per year, compared to 27,000 cases in the U.S. in 2013. Of the Florida cases, 77 percent were acquired by people when traveling to other states.
- Rocky Mountain Spotted Fever: In Florida, the reported incidence has increased markedly in recent years, possibly due to increased disease awareness and reporting, Kaufman said. Some 163 cases of the fever were reported from 2002 through 2011, and 77 percent were acquired in Florida. Again, most were in north and central Florida. Cases of Rocky Mountain Spotted Fever are reported year-round, though peak transmission is typically during the summer.
- Ehrlichiosis (HME)/Anaplasmosis (HGE): In Florida, 89 cases of Ehrlichiosis/HME were reported from 2002 through 2011. Of those, 33 cases of Anaplasmosis/HGA were reported. The majority of HME cases – 73 percent — are reported as being acquired in Florida, primarily in the north and central parts of the state. Like Lyme disease, HGA has less than half — 45 percent — of cases classified as Florida-acquired.
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. — 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. – Anyone can collect ant data as accurately as experts, if they have a bit of guidance and the right tools: cookies, index cards and plastic zip-top bags.
In a joint project between the University of Florida and North Carolina State University called the School of Ants, participants collected the insects at their homes, work or school. Using cookies to lure the insects, they bagged them, froze them, then sent them to labs so that ant experts could identify them and incorporate them into a national ants map.
Researchers at UF and N.C. State examined participants’ errors against mistakes of researchers trained in an N.C. State lab. Data from the two groups were virtually the same. Scientists say the similar findings came because the lay people followed their system.
The finding boosts the field of what’s called citizen science, a rapidly expanding area of data collection, said Andrea Lucky, an assistant scientist in entomology and nematology at UF’s Institute of Food and Agricultural Sciences. Lucky started the School of Ants in 2011, while a postdoctoral researcher at N.C. State, and brought the project with her to UF. The project is still going at both universities.

GAINESVILLE, Fla. — The contraption seems so simple, yet so clever, like something The Professor might have concocted on “Gilligan’s Island.”
Researchers at the University of Florida’s Institute of Food and Agricultural Sciences have devised a bedbug trap that can be built with household items. All you need are two disposable plastic containers, masking tape and glue, said Phil Koehler, UF/IFAS urban entomology professor. The traps catch and collect the bugs when they try to travel between people and the places where bedbugs hide, he said.
“This concept of trapping works for places where people sleep and need to be protected at those locations,” Koehler said.
GAINESVILLE, Fla. — The University of Florida’s Institute of Food and Agricultural Sciences is hosting its second annual Bug Week May 19-23 with activities for students, families and bug lovers around the nation.
“The UF Department of Entomology and Nematology is one of the best in the country,” said Ruth Hohl Borger, assistant vice president for UF/IFAS Communications. “Bug Week is a great opportunity for our researchers to excite the imaginations of children – and children at heart – about the bugs that live among us.” (more …)

GAINESVILLE, Fla. – A University of Florida entomology faculty member coordinates a global contest for students’ original insect research, and he recently announced the two winners for 2013.
The contest encourages students to research the natural history of pests, said Jiri Hulcr, a UF assistant professor in forest entomology and a member of UF’s Institute of Food and Agricultural Sciences.
For their research papers, Stephen Taerum, who attends the University of Pretoria in South Africa and Emily Meineke, a student at North Carolina State University, won the most recent contest, now in its second year, said. For winning, they shared the annual prize of $500.

GAINESVILLE, Fla. — In malaria-ridden parts of Africa, mosquito netting protects people from being infected while they sleep; now, a University of Florida entomologist wants to improve the netting by coating it with insecticide toxic only to mosquitoes.
The insecticide would work by interfering with an enzyme found in the nervous systems of mosquitoes and many other organisms, called acetylcholinesterase. Existing insecticides target the enzyme but affect a broad range of species, said entomologist Jeff Bloomquist, a professor in UF’s Emerging Pathogens Institute and its Institute of Food and Agricultural Sciences.
Acetylcholinesterase helps regulate nervous system activity by stopping electrical signaling in nerve cells. If the enzyme can’t do its job, the mosquito begins convulsing and dies. The research team’s goal is to develop compounds perfectly matched to the acetylcholinesterase molecules in malaria-transmitting mosquitoes, he said.
“A simple analogy would be that we’re trying to make a key that fits perfectly into a lock,” Bloomquist said. “We want to shut down the enzyme, but only in target species.”

GAINESVILLE, Fla. — When questions arise about mosquito control, University of Florida entomologist Roxanne Connelly is one of the state’s most sought-after experts. Now, that expertise has earned her the presidency of a national organization.
Connelly, an associate professor with UF’s Institute of Food and Agricultural Sciences, was inducted Feb. 27 as president of the American Mosquito Control Association at the association’s annual meeting in Atlantic City, N.J. She’ll serve a one-year term.
“I’m very pleased about it,” Connelly said in a March interview. “Holding this position is really an honor for me because I was elected to it.”
The election happened at the 2010 AMCA annual meeting, where members voted Connelly to a four-year leadership stint. In 2011 she began by serving a one-year term as vice president, then another year as president-elect, and now president. In 2014 she’ll become immediate past president.
