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.

Bug Week

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.

UF helping develop insecticide to target malaria-carrying mosquitoes

ENZYME PESTICIDE

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.

Huge, aggressive mosquito may be abundant in Florida this summer, UF/IFAS expert warns

GAINESVILLE, Fla. — If mosquitoes were motorcycles, the species known as Psorophora ciliata would be a Harley-Davidson – big, bold, made in America and likely to be abundant in Florida this summer.

Just how abundant is a matter of speculation, but University of Florida entomologist Phil Kaufman says last year the state had a bumper crop of the huge, biting insects, which are sometimes called gallinippers. He said there may be a repeat on the way.

“I wouldn’t be surprised, given the numbers we saw last year,” said Kaufman, an associate professor with UF’s Institute of Food and Agricultural Sciences. “When we hit the rainy cycle we may see that again.”

UF/IFAS expert: Female mosquitoes become savvy about other-species suitors

GAINESVILLE, Fla. — Talk about meeting Mr. Wrong.

Female yellow fever mosquitoes sometimes contend with the courtship and mating efforts of males from another, competing species – the Asian tiger mosquito.

She’s naïve, he’s sneaky. Both species spread dengue, a viral disease that’s a major human health threat.

In an ironic turnabout, Florida dengue cases may rise in the near future due to female yellow fever mosquitoes becoming savvy about the false-flag suitors, leading to increased yellow fever mosquito populations, says an expert with the University of Florida’s Institute of Food and Agricultural Sciences.

GAINESVILLE, Fla. — Termite control pioneer Nan-Yao Su and climate expert Clyde Fraisse of the University of Florida’s Institute of Food and Agricultural Sciences were honored for their international work this week, receiving a pair of annual awards.

Su, an entomology professor at the Fort Lauderdale Research and Education Center, received the International Fellow Award; Fraisse, an associate professor with the agricultural and biological engineering department in Gainesville, received the UF/IFAS International Achievement Award.

Both were recognized Thursday at a meeting of top UF/IFAS administrators. Jack Payne, UF senior vice president for agriculture and natural resources, and Walter Bowen, director of UF/IFAS International Programs, formally presented the awards.

UF/IFAS research: Typical populations of bedbugs can cause harmful blood loss in humans

Topic(s): Entomology and Nematology, Household Pests, Pests
GAINESVILLE, Fla. — For years, bedbugs have been turning up in sometimes odd and random places, such as subways, movie theaters, dressing rooms and schools, but scientists believed that to flourish, the insects would need more frequent access to human blood meals.

Turns out they don’t.

A new University of Florida study, published online this month by the journal Medical and Veterinary Entomology, shows the blood-sucking insects can do much more than survive — they can even thrive — with far less access to human blood than previously believed.
