CONTROLLING A VIRUS
LOMBARDI ON IFAS
MAIN A SPLASH
Not only are they tasty, but bighead carp act as aquatic janitors,
gobbling up troublesome algae that choke off the life of lakes, accord-
ing to IFAS research. IFAS scientists stocked sterile bighead carp in
experimental ponds dug next to and fed by Lake Apopka in Central
Florida. They found that bighead carp selectively ate a nuisance
algae, Botryocccus braunii. Research shows that 87 percent of the
bighead carp's food by dry weight was this algae that has proliferated
in Lake Apopka in the absence of natural enemies. "Some people
have used zooplankton (microscopic, animals) to eat the alga," says
Jerome Shireman. (Fisheries and Aquaculture). "But in the South, the
algae is often larger than the zooplankton, and the zooplankton don't
feed on it-so we tried fish."
Plant samples from the closed ecosystem in EPCOTs "The Land" in
Orlando could help scientists aiming to control a virus that stunts and
deforms many of the state's vegetable and ornamental crops. First
reported in Florida in 1985, the tomato spotted wilt virushas spread
throughout the state, carried by insects called thrips. In February,
IFAS scientists began a year-long study with researchers at the
Florida Department of Agriculture and Consumer Services, and the
Walt Disney World Co. to evaluate the susceptibility of plants within
"The Land" to the virus and to find a method of early viral detection in
plants. Although the virus has not yet appeared at "The Land", Walt
Disney Co. has provided a $49,000 grant to IFAS to get a jump on
what could become a serious problem.
During a speech Sept. 11 at McCarty Hall on "Science and the Univer-
sity," UF President John Lombardi said he was "really high on IFAS,"
praising the institute as "one of the pillars of strength at UF."
Lombardi said-he.s had no trouble whipping up enthusiasm.among
the state's constituencies for IFAS programs because IFAS has done
a good job in explaining the need for basic research to achieve
industry success. He said IFAS's method of transferring research,
education and services to the public is a model that should be copied
by other universities.
Two popular TV shows provided Shirley Bend (Hilaborough) with the
inspiration to teach water facts to state 4-H'ers. "Water Jeopardy"
teaches the basics of home water conservation, while "Water Wheel of
Fortune" reinforces water conservation concepts. Bond says she's had
"terrific success" with over 1,000 kids using the games in the past two
years, and another 12 states want to try them too. Although kids find
them fun, the games teach the facts; they're lased on conservation
recommendations from stateiwater regulation agencies.

High school students who take part in the Centers Program spend
eight weeks learning about the nature of agricultural research under
the supervision of a faculty member at an IFAS Research and Educa-
tion Center. Students design and conduct an experiment and are
Srequiredto submit-a scientific paper and make an oral presentation
before their peers and IFAS faculty. Jeaee Thompson (Agricultural
and Extension Education) congratulates the following IFAS Research
and Education Centers for their participation in the Third Annual IFAS
Centers Student Science Training Program, held from June 17 to Aug.

As of July 1, IFAS Information now coordinates production and
publication of all numbered extension and research publications and
Plan of Work and grant videotape and slildetape productions. The
contact for publications and videotapes is Julie Graddy and for
slidetapes, Gary Hermence. Their number is 904-392-7228. IFAS
Information also offers assistance in producing news releases and
magazine articles. Contact for news releases and articles is Susan
O'Rellly at 904-392-2411.
The Audiovisual Section of IFAS Information now has the capability to
produce slides from Harvard Graphics using 3.5-inch floppy discs as
5.25-inch floppies. "We have also updated to Harvard Graphics
version 2.3, but we're still experimenting to see how the new color
palettes are reproduced by our film recorder," says Ron Thomas,
(IFAS Information). As always, users should send their disks along
with account and encumbrance numbers to Bldg. 116 to the attention
of Thomas or Bill Peel.
