Ryan Hewlett (Tom Hewlett's son) won first place in the environmental science division at the Fort Clarke
Middle School Science Fair. The title of his project was "Using capsaicin to control root-knot nematodes."
He found that capsaicin, a chemical found in hot pepper plants, repels root-knot nematodes in the soil. His
project was also selected for the regional Science Fair that will be held in Gainesville at the O'Connell
Center in January. Ryan is excited about this finding and plans to continue his research in trying to find the
best rate and mode of application of this organic compound.
Congratulations to Chuck Strong for being the department candidate and recipient of the ESA Southeastern
Branch Kirby L. Hayes Award for outstanding research in a masters program.
Congratulations to Dr. Don Dickson, Dr. Don Hall, Dr. Freddie Johnson, and Dr. Philip Koehler for
receiving a Professorial Excellence award. This honor recognizes their outstanding accomplishments as
professors in our university in teaching, research and service. The Professorial Excellence Program, funded
by the Florida legislature, exists to identify and reward those faculty with long-term commitments to the
university who have accumulated exceptional records of achievement at the University of Florida after at
least 10 years of service after promotion to full professor rank. The University of Florida can offer few of
these awards, and this honor represents a strong endorsement of continued superior service to the university
and the state of Florida.
Dr. Dale Habeck and Dr. Julio Medal were awarded a grant of $150,000 from the USDA and Florida
Department of Agriculture-DPI for screening of potential biological control agents of tropical soda apple,
Solanum viarum, in Florida. This two-year project will be conducted in collaboration with Dr. Robinson
Pitelli, Universidade Estadual Paulista, Jaboticabal campus in Sao Paulo State, Brazil. Dr. Habeck will
celebrate his retirement with this new research project. Dr. Medal will be traveling to South America to do
explorations, insect collecting and importation for host specificity screening at the DPI quarantine in
Congratulations to Dr. Marjorie Hoy for being named a fellow of the Entomological Society of America.
From a letter from Mark Griskey from the National Academy of Sciences to Dr. Tom Walker:
"Congratulations, the National Academy Press has selected the UF Book of Insect Records site as the cool
science link of the day on December 9. The National Academy Press is the publisher for the National
Academy of Sciences, National Academy of Engineering, Institute of Medicine and the National Research
Council. The National Academy Press Web site is http://www.nap.edu/."
Congratulation to the following students graduating this semester: Jaw-Ching Liu (Ph.D.), Zhongxiao Chen
(Ph.D.), Eliane Quintela (Ph.D.), Tonya Van Hook (Ph.D.), Sami Ur-Rehman (Ph.D.), Kerry Schwartz (M.
S.), Richard Worth (M.S.) and Aliska Akers (M.Ag.).
Robin Goodson is leaving this week for Raleigh, NC. He will return in February to defend his Ph.D
dissertation. He is getting married in March.
Many of you missed it while you were at the ESA meetings, but Ph.D. student Dini Miller was the subject
of an entire page in the Alligator, UF's student newspaper, on Tuesday, December 10th. The article covered
Dini's work with cockroaches, insect zoos, and local school students.
FROM THE INCOMING GRADUATE COORDINATOR
As you know, on 1 January 1997 I assume the role of Graduate Coordinator. I look forward to working with
you during the next couple of years and helping you in any way that I can. I must confess that I do not know
all of you; thus, I invite each of you to drop by at your convenience so that we can become acquainted.
Except when I have an engagement, such as a class to teach, my door will be open to you. And as you
already know, Debbie Hall is available to assist you with most of your concerns. -- Grover Smart.
FACULTY, STAFF AND STUDENTS NEWS
Dr. Thomas Baum from Iowa State University was invited to speak at the department November 21. Dr.
Baum presented the seminar "Plantibodies: A novel approach to engineering plant resistance to nematodes."
He also visited with faculty and graduate students and discussed the challenges and potentials of this new
approach for managing nematodes.
Dr. Gene Gerberg and Dr. Ross Arnett presented a talk and slide show on "The Galapagos after Darwin" at
the annual meeting of the Center for Systematic Entomology at the DPI auditorium on December 2.
Dr. Gene Gerberg will be the invited luncheon speaker on January 30th at the Dodd Short Course, at the
Radisson. Dr. Gerberg will speak on "An environmental assessment of a malaria program in Sri Lanka."
Dr. Tom Sanford was recently invited to the 11th Congreso Braxileiro de Apicultura in Teresina, Brazil.
This area called the Sertao is the next big beekeeping frontier using Africanized honey bees. Dr. Sanford
gave presentations on using electronic communications and the WWW. There are three Internet providers in
Teresina; since his presentation, four beekeepers in the area have contacted Dr. Sanford through his updated
home page. Dr. Sanford presented information on nutritional management of honey bees. He was the only
speaker invited who is currently residing in the United States. He spoke in Spanguese (hybrid Spanish/
Portuguese). Beekeeping congresses are held every two years in Brazil.
Pauline Lawrence attended the annual meeting of the Entomological Society of America in Louisville, KY.
She served her third and final year as a member of the governing board of the society. She initiated and
gained approval for the "ESA Recognition Award in Physiology, Biochemistry and Toxicology."
Subsequently, members of Section B secured sponsorship of the award by Rohm and Haas in the form of
$1,500. The annual award is now open to all ESA members who have made significant contributions to
basic or applied entomology through studies in physiology, biochemistry or toxicology. The recipient will
be presented with a check and an ESA plaque at the annual meeting. Look for the call for nominees in the
ESA newsletter in early 1997.
Dr. James Cuda also attended the annual meeting of the Entomological Society of America. Cuda organized
and moderated an informal conference for the International Organization for Biological Control/Nearctic
Regional Section Weed Biocontrol Working Group. Thirty-seven scientists representing the United States
and Canada participated in the conference, which featured two invited speakers: Dr. Judy Myers, an
ecologist from the University of British Columbia, and Dr. Doug Boyette, a USDA plant pathologist from
Stoneville, Mississippi. Both speakers provided interesting insights into the theory and practice of weed
Many students and professors from the Entomology and Nematology Department attended and presented
talks and posters at the ESA annual meeting in Louisville, Kentucky December 9-12. Poster presenters:
Marco Toapanta and Pauline Lawrence: "Developmental profile of a 24 kD parasitism-specific protein from
the Caribbean fruit fly, Anastrepha suspense, parasitized by Diachasmim orpha longicaudata: A western
blot analysis." Denise Johanowicz: "Molecular and biological studies of Wolbachia in the western predatory
mite and twospotted spider mite." Clay Scherer: "Response of grasshoppers to different forest management
practices in a longleaf pine ecosystem in southeastern United States." Carlyle Brewster: "Large-scale

WWW SITE PROVIDES CURRENT PESTICIDE LABELS
Recent inquiries from County Extension faculty about label information sent me scrambling for the all-
important label books that pest specialists try to keep current on their shelves. Because of the need to be
sure that my information was correct, I tried a WWW site that was recently recommended by a colleague
from another state as a good source of current label information. The company from which I needed current
label information was represented, and the file had been revised within the month! This site can be a big
help to state and county faculty who need to see labels for products from the companies who subscribe to
The site, called Information Services for Agriculture, is a private "full-service" provider of info on the web
for agriculturally involved clients, including labels. The address is: http://www.aginfo.com/. I am not sure if
every possible label of these companies is listed, but the product I was investigating was thoroughly
documented, including Florida only and California only labels.
Of course, some companies may choose to post their labels only on their own websites, so check company
by company if this service does not have the label you need. -- Dr. Robert Dunn.
CHRISTMAS COOKIE COMPETITION
Jane Medley received the best cookie prize at the department Christmas party on Sunday. This is the recipe
for those who would like to try it out:
Molasses Sugar Cookies: 3/4 cup cooking oil, 1 cup sugar, 1/4 cup molasses, 1 egg, 2 cups all-purpose
flour, 2 teaspoons baking soda, 1 teaspoon cinnamon, 1/2 teaspoon cloves, 1/2 teaspoon ginger and 1/2
Cream oil and sugar. Add molasses and egg; beat well. Mix remaining ingredients and add to the first
mixture. Mix well and chill dough. Form into 1 inch balls. Roll in sugar and place on greased cookie sheet.
Bake at 375 degrees for eight to 10 minutes. Makes about four dozen cookies.
Debbie Hall reminds students January 3 at 4 p.m. is the deadline to register for Spring 1997 term without a
$100 fine. See Debbie if you need help in registration. Also, professors and students need to make sure that
the letter of appointment has been signed and turned in for the fee waiver before January 6, 1997.
Dr. Gary Simone (Plant Pathology), Dr. Don Short (Entomology) and Dr. Bob Dunn (Nematology)
announce Landscape IPM: Ornamentals and Turf, PMA 4242, Section 4531, 3 credits. This course will be
offered in Spring 1997.
INSECT MANAGEMENT GUIDE
The Insect Management Guide available through the OnLine Database on the VAX will no longer be
available after this month. However, you still can access the Insect Guide, as well as the Nematode
Management Guide, through the department's WWW site under the Publications button. Hundreds of
extension publications are available that offer information on biological, cultural and reduced pesticide
control and management through the site: http://entnemdept.ifas.ufl.edu/.
Gregg Nuessly, Ken Pernezny and David Schuster have posted their Vegetable Newsletter No. 2 (1996-
1997) in Pest Alert at http://PestAlert,ifas.ufl.edu/. This file is devoted to the appearance of damaging
western flower thrips in pepper field in southeast Florida. It covers damage, diseases and control strategies.
Since last month's issue information has been added to Pest Alert on the new southern pine beetle outbreak
in Marion county; on the new Landscape IPM course offered by Dr. Bob Dunn, Dr. Don Short and Dr. Gary
Simone; on the new Nemacur restrictions for citrus; thrips on peppers; and other problems. (Not that Drs.
Short, Dunn and Simone are problems.) Pest Alert is available at http://PestAlert,ifas.ufl.edu/.
ESA TO OFFER ELECTRONIC REPRINTS
At the recent Entomological Society of America meeting in Louisville, the governing board voted to offer
ESA authors the option of buying electronic reprints, beginning as soon as possible and no later than
January 1998. The price is to be commensurate with that of paper reprints. Articles in ESA journals by
authors who choose to purchase these reprints will be freely available everywhere on the Internet all the
time, as those published in Florida Entomologist have been since 1994.
A hard copy of this newsletter is given to department members in Building 970 only. All others can obtain
an electronic subscription by joining the listserv.
