Dr. Chen Shu Chen, Unnersit' of Florida Professor of
S Food Engineering, is retiring after 14 years at CREC. His
S accomplishments in citrus processing include the develop-
ment of a new technique to clarify\ fruitjuice. This process
can be used by the industry to improve current citrus juice
processing and develop new juice products. Dr. Chen has
authored several key papers and books in the area of food engineering and juice
Dr. Chen v\ ill be honored at a reception on Thursday, September 30, 3:00 pm at the
Ben Hill Grifiln. Jr. Citrus Hall. Everyone is invited for cake and refreshments. Take
this opportunity to thank Dr. Chen for his many contributions to CREC and to wish him

CREC Packinghouse Day:

Canker, Fruit Cooling Hot Topics As Citrus Packers

Look To New Season

LAKE ALFRED Over 350 people from the citrus fresh fruit
industry gathered at the 38th Annual Packinghouse Day at the
University of Florida (UF) Citrus Research and Education Center
(CREC) on August 19. The event featured speakers and exhibits
on frcsh fruit packing. Canker and fruit cooling were among the
topics of the day.
The meeting was opened by Dr. Harold Browning, CREC
Center Director, and Dr. Mike Martin, the UIF Vice President of
Agriculture and Natural Resources. Dr. Mohamed Ismall, Fresh
Fruit Scientific Research Director of the Florida Department of
Citrus (FDOC). presented an overview of the department's work
on fresh fruit sanitation and fresh-cut citrus.
Martha Roe-Burke. Florida Citrus Commissioner and Chair-
person of the FDOC Food Service Committee, was the oral ses-
sion moderator. She applauded the FDOC's efforts in promoting
the health benefits of citrus, noting that the recent upswing in
grapefruit juice sales indicates that these powerful messages are
reaching consumers.

Scenes From Packinghouse Day.....

Canker A Concern
With canker now in five Florida counties, the citrus industry
has plenty to be concerned about, warned Leon Hebb and Ken-
neth Bailey of the Florida Department of Agriculture and Con-
sumer Services.
Citrus canker is a bacterial disease that affects grapefruit, or-
anges, limes and several other types of citrus. Diseased trees have
lesions on the fruit, stems and leaves, and suffer a decline in fruit
productivity and general tree health. The only way to prevent the
spread of canker is to remove and destroy affected trees.
Hebb, who is Chief of the Bureau and Pest Eradication and
Control, said that if canker continues to spread, it will change the
industry. "I believe we cannot continue to raise fresh or processed
grapefruit with canker [in Florida]", Hebb told the audience, many
of them grapefruit packers. Florida is currently the world's larg-
est producer of grapefruit.
Bailey, Citrus Canker Eradication Program Director in Miami,
outlined current eradication efforts throughout the state. Their
strategy is based on early detection and immediate removal of in-

CREC Travelogue..... Costa Rica
A Natural Paradise in Central America

Costa Rica is located in Central
America (see maps above). It is a scenic
country, and with 25% of its land set aside
as national parks or as research areas,
Costa Rica is dedicated to preserving its
natural beauty.
Costa Rica is a strong, democratic na-
tion and is considered very political)

stable. The country gained its indepen-
dence from Spain in 1821. Unlike other
Latin countries, Costa Rica has a large
middle-class. The country's health and
educational systems are excellent.

What Are Mites?

Mites are arachnids, not insects.
Arachnids are a class of arthropods
that includes scorpions, spiders, mites
and ticks.

Acarology is the study of mites. Dr.
Carl Childers leads CREC's research
program on mites pests of citrus.

Some mites are beneficial because
they feed on other mites and insects.
Some beneficial species are used in
agriculture for pest control.

Some mites cause considerable
damage to citrus and other crops.
Depending on the species, mites can
cause fruit blemishes, hurt fruit
production and damage leaves, stems
and other parts of the tree.

Mites In Your Home: Dust mites are
common inhabitants of the human
household. They are not harmful, but
many people are allergic to them.

Chiggers are the larvae of a particu-

fected trees. The agency has employed
over 550 employees in Brow ard and Dade
Counties alone, where canker was found
in 195,.
Bailey emphasized the importance of
the eradication efforts, noting that eradi-
cation is a small investment compared to
the effects on Florida's economy if canker
continues to spread.
To date, over 400,000 trees have been
removed from Broward and Dade coun-
ties alone. Although this area is primarily
urban, there are over 200 acres of com-
mercial citrus in these counties. These
commercial citrus operations are mainly
small "mom- and-pop" businesses, but the
ban on moving fruit out of canker quaran-
tine areas has had a devastating effect on
their incomes, Bailey said.
Hebb urged the packers to follow the
required sanitation procedures and guide-
lines for fresh fruit packing and transport,
warning them that if the\ let their guard
down, they could regret it later.
It is not uncommon for canker to go
undetected for a year before the infesta-
tion mushrooms, Hebb told the audience.
"[If you have] any suspicions that you may
have a problem, don't hesitate to pick up a
phone and make a call," he urged.

Keep it Cool
Postlhanest pitting is a disorder char-
acterized by unsightly blemishes on the
peel. The blemishes, which are brown-
black depressions, or "pits", render the fruit

unacceptable for fresh market. It is a prob-
lem that has plagued many a fresh fruit
These "pil'" are actually groups of col-
lapsed oil glands in the peel. The combi-
nation of warm temperatures and wax coat-
ings on the fru it lead to the development of
these blemishes.
The remedy is straightforward. although
not all that simple, explained Dr. Huating
Dou, FDOC/CREC scientist. Cooling the
fruit and keeping it cool can dramati-
cally reduce the incidence of postharvest
Dou demonstrated that it is also impor-
tant to cool the fruit as soon as possible af-
ter packing. In a study with grapefruit and
Fallglo tangerines, postharvest pitting was
reduced if the fruit was cooled within a day
after packing. However, if the fruit is al-
lowed to sit at a warm temperature just two
da\ s prior to cooling, the incidence of
postharvest pitting increases substantially.
Dou stressed that rapid cooling and consis-
tent low temperature storage are key to re-
ducing postharvest pining
To cool the fruit, two pre-cooling sys-
tems room cooling or forced air cooling -
can be used in the fruit packinghouses.
These systems offer big advantages because
truck-trailer coolers are not designed to cool
the fruit, only maintain its temperature, ex-
plained Dr. Will Wardowski, UF CREC
scientist and Packinghouse Day organizer.
Fruit cooling not only helps reduce
postharvest pitling. but reduces fruit decay
and water loss.

is used in packinghouses to hasten color
development in ripe oranges. The process,
called degreening. is typically used for
early-season fruit.
Ethylene is the same gas that ,given off
by fruits such as bananas and tomatoes. It
is the ethylene that hastens ripening when
you place these fruits in a closed paper bag
for a few days. In oranges, ethylene does
not affect fruit ripening, but it can be used
to degreee" the fruit.
In the past, electronic devices for mea-

The Pacific Northwest
The opporrunir, to pursue a master's
degree arose when the chairman of Wash-
ington State University's Dept ofEntomol-
ogy expressed an interest in new graduate
students. Hugo was offered a graduate as-
sistantship and decided to pack his bags
and head north.
After completing his master's degree at
Washington State, Hugo intended on re-
turning to Costa Rica. but his good friend,
Ronald Ochoa, encouraged him to continue
his education. He told Hugo he didn't want
him to come home to Costa Rica until he
got his Ph.D.

Gator Country
Now, Hugo is working towards that
Ph.D. with Dr. Carl Childers at CREC.
Hugo first came to Florida in 1Q95, and
spent a semester in practical training with
Dr. Childers at CREC before enrolling in
the UF graduate program in January 1996.
Hugo is conducting studies on the
Tydeidae family of mites on citrus. He is
studying the biology, ecology and tax-
onomy of th is diverse group of mites, com-
mon to citrus groves.
Taxonomic identification of these mites
is complex and relies on morphological
characteristics such as the number and
placement of setae (chetotaxy). Hugo is
currently working to identify the species
found on Florida citrus and conduct fur-
ther studies that will help us learn more
about this family of mites.

Hugo is enjoying his graduate work at
CREC, noting that it has offered him many
valuable opportunities. He is especially
grateful to Dr. Childers for the opportunity
to travel to national and international sci-
enttfic meetings, where he has presented his
research and met other scientists in the field.
The chance to travel around the U.S. and to
other countries on mite and insect collect-
ing trips has also been beneficial to him, he

Other Interests
Hugo lives in Lake Alfred. and was a
member of CREC's Championship Soccer
Team this spring. Hugo is great. interested
in natural history, and lest you think he is
only interested in small organisms, he loves
reading about dinosaurs and lcam ing about
their natural history, too. Music and mov-
ies are among his favorite pastimes. L

History: When Christopher Columbus vis-
ited what is now Costa Rica on his fourth
(and last) voyage to the New World, he saw
Indians wearing sparkling adornments.
Thinking this was the land of riches, he
named the area Costa Rica, or "rich coast."
Ironically. Costa Rica lacks gold and silver
mines, and was one of the more sparsely
populated areas in Central America.
The absence of minerals, as well as the
small Indian population, meant that early
Spanish settlers had to farm their own land.
This lead to the creation of a large middle
class of farmers. These are some of the fac-
tors helped shape the social and economic
structure that still exists in Costa Rica to-

noticed at all. But Jack was seldom silent, and rarely did a day go by when he didn't share with his friends some great joke or anecdote. This
is the Jack we all knew and the Jack we ill always remember. This is the Jack who brightened our days with his celebration of life.
But there was so much more to Jack that unfolded with time, over early morning cups of coffee and late night encounters in the lab while
doing my research, that I am grateful to have known him, and thank God for his friendship.
From his pictures, we all knew that Jack loved to draw. The humor in his caricatures of some of us, showed that he saw the funny side of
life, especially to those of us who take life too seriously. But Jack didn't just draw pictures, Jack loved art, the art of life with all its motion.
color, vibrancy and light. He wondered at all things great and small. You could show him, under the microscope, life, teeming in a drop of
water, or talk about the wonder of DNA. He would excitedly tell me about some amazing show he saw on Discover about insect communi-
cation or the memory of elephants. He was genuinely interested in the work we do here, and was able to share in the excitement of our
But, maybe you didn't know that Jack loved to work of the impressionist painters. That Degas was his favorite who, with his dancers,
captured the simplicity of motion and the beauty of the female form. Or that he was captivated by Manet's "Abysinth Drinker," moved by the
depth of a past life, painted into a woman's expression. Jack loved folk music most, but he would memorize and sing words to country songs
so pathetic that, to him, they were funny. He found it interesting that the great composers like Mozart, Haydn, and Beethoven and the great
impressionists like Cezanne. Renoir and Monet all came together in a time synchrony, like artistic renaissance.
Jack loved the old west, gunslingers and heroes. He loved stories and artists' renditions of that past era. Some of us may still have some
of his sketches of cowboys and Indians Jack liked the openness and solitude of the wilderness. He lived several months in a tent one time,
just for the experience. He liked powerful cars and Harley Davidsons, and was recently considering getting a "chopper" just for old time's
sake. Jack enjoyed shooting skeet and target practice. Some of us went shooting w ith him. He taught me how to shoot the ten out of a target.
He told me once how much he liked to story of Don Quixote. He drew sketches of Don Quixote, his sidekick Sanco Panchez and their silly
donkey in their quest for love and the meaning of life. He was amused by Don Quixote's absurd sword fight with the behemoth windmill.
Jack was compassionate. He offered his friendship generously to everyone, and everyone who knew Jack loved him. He had friends at
Albertson's. He teased the women at Lifestyle's. We at CREC who knew him felt his friendship. He looked after his father in his gradual
decline. He seemed to love family and friends without condition, near and far. I rarely heard him say anything bad about anyone.
Jack and I talked about religion, creation, and the origin of life and its meaning. We talked about being a part of a vast comoleceness or
oneness. Though he claimed to be agnostic. he felt that in some way we go on. He liked the idea of reincarnation and believed in an
underlying power and order to all things. We talked about death. Jack and I. How it seems to be the punctuation mark of this life, well spent
in adventure and discovery, and a step into the next.
Jack is gone from us now and we will miss him. But, the manner of his passing unimportant, and not for us to understand. A single
definitive act in a lifetime of existence is not the measure of a man. I would not want my life to be rated on a decision made at a point of great
confusion, even if it was the last decision of my life. I will not do this to Jack, who brought so much friendship, laughter and love to those lives
he touched. Denise Dunn

Schools, Tours and Science Fairs -
School Visits, Tours
Monica Lc andos sk i, Public Relations Coordinator, will visit schools and conduct or
coordinate tours for schools and other visitors. She will also help out with science or citrus-
related questions from students. If you ever receive these types of requests and would like
Monica to coordinate or assist with these efforts, please contact her.

Would You Like To Be A Science Fair Judge?
If you are willing to be a science fairjudge, please contact Monica, as she is compiling a
list of potential judges. We sometimes receive requests for science fair judges from local
schools, and we also need judges for CREC awards at area science fairs. If ou have any
interest in students, you'll probably find it a fun and worthwhile experience. It's an excellent
opportunity for students, post-docs. biological scientists and others here at the center.
Science fairs need judges with math, computer and other related backgrounds as well as
biology, chemistry and other related fields. It typically requires a half or sometimes a full
day to participate as a judge.
