In addition to the printed version of this newsletter that is distributed through the department, there is an
electronic version that goes far afield. The electronic version is delivered by means of a list server to which
people can subscribe or unsubscribe as they wish. As of April 14th, 170 subscribers elected to have copies
delivered to their e-mail boxes once a month. Since the list is moderated, this is the only message that these
subscribers receive from this address
Of the 170 subscribers 12 are currently from within the department and another nine from the Florida
Department of Agriculture, mostly entomologists and nematologists at the Division of Plant Industry.
There are subscribers from Departments of Agriculture from several other states too. The USDA is also
well represented, not only from the two laboratories in Gainesville, but from around the nation. Other
subscribers include university scientists from Rutgers, Oregon State, Colorado State, the University of
Hawaii and others. Many of our colleagues from the 21 UF/IFAS research centers throughout Florida are
also subscribers. If you don't count Disney World (this imagi-nation has one subscriber) then there are
subscribers from at least 14 other nations.
A few of the countries represented are Brazil, Iran, Mexico, Italy, Thailand, South Africa, Costa Rica,
China and Russia. Tom Fasulo, the "owner" of the list server, couldn't identify all the country
abbreviations, nor could he identify individuals from other countries who subscribe under an address that
does not include a country identifier.

Pete Coon has been selected by the National Association of Colleges and Teachers of Agriculture
(NACTA) Teacher Recognition Committee to receive the NACTA Graduate Student Teaching Award.
Pete and his nominator, Dr. Don Hall, have been invited to attend the NACTA Banquet this June at which
time Pete will receive his plaque.
Cynthia Khoo, a Ph.D. student in the laboratory of Dr. Lawrence received a certificate of recognition from
the International Student Services office for maintaining a 4.0 GPA in all her course work. Fahiem
Elborai Kora, a Ph.D. student of Dr. Larry Duncan (CREC Lake Alfred), won first place in the Best
Student Paper competition at the 32nd International Organization of Nematologists in Tropical America
(ONTA) meeting held in Auburn, Alabama. The meeting lasted one week and involved several
presentations and posters. Some credit his success with the color of his poster, a chic but sophisticated
shade of pink. In reality, nothing can replace the hard work and effort necessary to produce an award
winning poster, whatever the hue.
Congratulations, Pete, Cynthia and Fahiem!
Dr. Gene J. Gerberg was invited to Crystal City, VA by the U.S. Environmental Protection Agency to
serve as a member of the Scientific Advisory Panel. The panel met on 7 April and discussed "Insect
repellent product performance testing guidelines".
Dr. James P. Cuda participated in half day workshop for extension professionals on the Distance
Diagnostics and Identification System (DDIS) held at McCarty Hall, 4 April. DDIS is a new Web-based
system that uses digital cameras to send photographs of insects, weeds, and diseased plants from the field
to the lab for rapid identification and diagnosis.
Dr. A. Charles Tarjan was the introductory speaker at the opening ceremonies of the biennial meeting of

Millennium, March 22-24, 200 in Washington, D.C. The meeting, co-sponsored with The Smithsonian
Institution met in the Smithsonian. One of the most memorable events was the keynote talk by Ernst Mayr,
who was the awardee of the AIBS Distinguished Service Award. Dr. Mayr, who was born in 1904,
presented a thought provoking and vigorous talk on evolution! At the age of 97, Dr. Mayr is currently
working on THREE books; he is the author of more than a dozen books and many other publications on
evolution. Plenary speakers included Stephen Jay Gould, Daniel Janzen, Gene Likens, Lynn Margulis,
Gordon Orians, Ghillean Prance, Marvalee Wake and E. O. Wilson, who were charged with reviewing
major advances in organismal and integrative biology during the last century and to speculate about future
challenges and opportunities. The meeting also included a Town Meeting on Teaching Evolution in
association with the National Association of Biology Teachers. The next AIBS meeting will take place in
Washington, DC in March 2001 and the theme will be "From Biodiversity to Biocomplexity". The AIBS
meetings are a wonderful opportunity to gain a broad perspective on organismal biology and ecology.

The Spring Picnic was arguably the most successful event of the year! The picnic was held on April 1st (no
foolin'!) at Lake Wauburg. Food was provided in large part by Sgt. Hanley, whose generous donation of
thirty pizzas kept energy levels high, as well as various dishes provided by the students and faculty in
attendance. Games of ultimate Frisbee, kickball and whiffleball interspersed with canoeing and kayaking
added to the day's enjoyment. The ENSO Social Committee would like to thank everyone involved in
making preparations for the picnic, and special thanks to Sgt. Hanley for providing enough food for an
"army" of entomologists and nematologists!
Team ENSO continued to support community endeavors earlier this month by sending a team of students
to participate in the MS Walk 2000. The 5K event began at the Hippodrome theater and ended with free
pizza from Dominoes and prize giveaways. Katie Barbara won a $25 gift certificate to CJ's and Erin
Britton won a white-water rafting trip for two. The team had great fun and raised over $500. Thanks to
everyone who participated and supported the cause:
Katie Barbara team captain Juan Alvarez Erin Britton Eric Hansen Shane Hill Clint McFarland

CITRUS GROWERS STRUGGLE WITH ROOT WEEVIL
LAKE ALFRED Citrus growers were reminded of the costly and catastrophic consequences of spreading
diseases and pests such as canker and Diaprepes root weevil at the Diaprepes Short Course at the UF/IFAS
Citrus Research and Education Center (CREC) on March 22. "We must preach and practice sanitation,"
implored Haines City citrus grower Buster Pratt, referring to sanitary practices, including appropriate
cleaning of farm equipment and tools, to prevent the spread of pests and disease. Pratt has been one of the
citrus industry's leaders in the battle against the Diaprepes root weevil, a devastating insect pest that many
refer to as "The Evil Weevil."
Diaprepes root weevil feeds on citrus, ornamental plants, sugar cane and nearly 300 other plant species.
Native to the Caribbean, it was first found in an Apopka nursery in the 1960's. Since then, the insect has
spread to 140,000 acres in Florida, and costs in the citrus industry now exceed $72 million annually.
Because the insect does not travel great distances on its own, much of its spread has been attributed to
man's movement of infested material.
The one-day Diaprepes Short Course, organized by UF Citrus Extension Agent Dr. Steve Futch, provided
an opportunity for growers, crop advisors and others in the citrus industry to learn about pest management
practices for this destructive insect. Over 140 people from throughout Florida's citrus-growing regions
were in attendance.
The problem isn't just the Diaprepes root weevil, warned Dr. James Graham, CREC plant pathologist.
Damage to tree roots by larval feeding increases the tree's susceptibility to fungal infection by
Phytophthora. The combination of Diaprepes and Phytophthora is a devastating 1-2 punch for the tree,
causing a rapid decline in root health and subsequently, its productivity. Improved soil drainage, careful
irrigation and fertilizer management and chemical treatments for Phytophthora were recommendations for
helping trees withstand the Diaprepes-Phytophthora complex.
According to CREC's Dr. Clay McCoy, an integrated pest management program for Diaprepes root weevil
includes foliar insecticides to control adults and eggs, soil-applied insecticides and parasitic nematodes to
control the larvae underground, chemical treatments for Phytophthora fungal infection, and good
horticultural care to improve tree tolerance to root damage caused by the larval feeding. Although these
treatments are expensive, CREC economist Ron Muraro presented a cost-benefit analysis that indicated
investments in Diaprepes pest management will pay off in improved production.
Florida's citrus and ornamental nurseries are also impacted by this pest, pointed out Dr. David Hall, a
researcher with the U.S. Sugar Corporation in Clewiston. And lest growers think the Diaprepes root weevil
is their only concern, this insect has a lot of relatives. Dr. Charles O'Brien, Florida A&M insect
taxonomist, said that weevils are a part of the largest family of living organisms known, with more than
65,000 described species, and thousands more undescribed species throughout the world.
The University of Florida, U.S. Department of Agriculture, Florida Department of Agriculture and
Consumer Services, U.S. Sugar Corporation, Kerr Center for Sustainable Agriculture and other universities
and agencies are conducting research on many fronts to find better pest management options for one of the
biggest challenges facing the citrus industry today.

ARS applies for a patent for BEETLBAR, a new plastic barrier that blocks pesky beetles from boring into
wood structures. It will save poultry farmers money in losses from beetle-damaged broiler houses that cost
thousands of dollars more to heat and cool than undamaged houses. Beetle-damaged insulation can cost
more than $30,000 a house to repair. ARS researchers developed this nontoxic barrier, which can be placed
around trees, poultry house foundations, and a variety of residential, commercial, industrial, and farm
buildings. Two insects in particular pose problems for poultry farmers darkling beetles, also called lesser
mealworms, and hide beetles. The larvae of these beetles develop in poultry litter and manure under high-
rise poultry houses, then crawl up walls and posts into ceiling insulation, burrowing many holes and
causing major structural damage. In Georgia and Virginia alone, annual losses from these insects are
estimated at $9.8 million and $15.9 million, respectively. BEETLBAR's slick surface prevents this
migration. Another problem: Floor-reared birds feed on migrating beetles, which can harbor Salmonella
typhimurium, Escherichia coli, tapeworms, and avian leukosis virus, leading to major economic losses for
farmers. The new barrier is strong, long lasting, lightweight, and easy to apply and clean. It is pesticide free
and it reduces pesticides needed to control litter beetles. ARS has filed for a patent on this new invention
(PATENT APPLICATION NO. 09/216,513). For more information, contact David A. Carlson

The Pest Alert WWW site and list server was intended to serve scientists and growers within the state of
Florida. However, numerous individuals from universities, government agencies and industries from
outside the state have joined the list server. And as of April 1st, there were subscribers from at least 16
other countries that list owner Tom Fasulo could identify. The response to the information and links posted
on Pest Alert is always interesting. For example, on April 4th Phil Stansly of the SW Florida REC
requested that a link to that center's biological and chemical insecticide reports be added to Pest Alert. A
short notice was sent to list subscribers notifying them of this addition. Within hours, Dr. Lee Eavy, IPM
and Crop Protection Team Leader for Northern Marianas College on Saipan, responded with the following,
"Thanks so much for your notice. I have been looking for current information on silverleaf whitefly and
Helicoverpa management options for weeks now, in my new position here on Saipan. I also need to find
IPM program/system options for these and other pests, including DBM and phytophagous lady beetles and
aphids, that we can adapt to our tropical agriculture conditions in vegetable production here. Small (1-5
ha.) family-owned farms are the rule here." The Pest Alert site, with instructions for subscribing to the list,
is available at http://PestAlert,ifas.ufl.edu/.
CITING ONLINE SOURCES
Tom Fasulo has been using a WWW site that displayed examples of citing different online sources as a
guide for his WWW sites and the department's Featured Creatures publications. He recently accessed this
site again and found that it has moved to the Columbia University Press WWW site for Online Style. Tom
also noticed that the format for citing online sources has changed somewhat. For details on how to cite
online sources, access the Columbia Guide to Online Style at http://www.columbia.edu/cu/cup/cgos/ There
are different styles for the humanities and sciences.
