Research Tax Approved
Citrus growers approved the Florida Citrus
Production Research Advisory Council research
"box tax" for another six years. In a January
mail referendum, 652 citrus growers (76 percent)
representing 87% of Florida's citrus acreage
voted in favor of the tax, which is currently 0.75
cents per box of citrus harvested. The tax has
raised more than $18 million during the past 12
years and provides funding on areas such as
plant improvement and breeding, citrus tristeza
virus, Diaprepes root weevil, foliar fungal
diseases and precision agriculture. For
information onbox tax projects, FCPRAC annual
reports are posted on their website:

Meet... The Childers Lab

Dr. Carl Childers' program on mite and insect pests of citrus was recently
highlighted for the CREC section of the 2003 UF/IFAS Annual Report, to
be printed later this year. Below are excerpts from Dr. Childers' research
report highlight, and an introduction to his research team.


Plant feeding mites in four
different acarine families his-
torically have been a problem
for Florida citrus growers at
one time or another and in-
clude: pink citrus rust mite, cit-
rus rust mite, Texas citrus mite,
citrus red mite, six-spotted
mite, one to three species of
false spider mites in the genus
Brevipalpus, and the broad
mite. Within the past 40 years,
citrus growers have been con-
cerned mostly with the impact
of rust mites, especially on
fruit. Rind blemish damage to
fruit, juice quality, yield and
bonding force reductions are
all associated with citrus rust
mite feeding injury on Florida
citrus and may impact both
fresh and process fruit grow-
ers.
Dr. Carl C. Childers, UF/
IFAS Professor of Entomology
at CREC, conducts research in
both acarology and entomol-
ogy to better understand the
biology of different pest mites



Dr. Carl C. Childers
was born in Lexington,
Kentucky, but also lived in
Michigan, Kansas and
Missouri. After graduating
from high school in Kansas
City, Dr. Childers served 10
years in the Naval Reserves
and 2 years active duty on the
U.S.S. Seminole. Afterjunior
college, Dr. Childers enrolled at
the University of Missouri,
where he eventually decided to
pursue entomology. He also
obtained a master's degree at
the University of Missouri,
where he studied a medical
veterinary problem caused by
biting midges.

but soon moved to a job in
Northern Illinois. Three years
later, he returned to graduate
school at the University of
Missouri and completed his
doctorate in 1974. His Ph.D.
research involved integrated
mite control in apples.


Amy Lane is a Senior
Laboratory Technician in Dr.
Childers' lab. A Winter Haven
S. native, Amy graduated from UF
-' with a degree in natural resource
S.*. a 4 recreation management. Amy
worked for the Florida Park
Service as a ranger at the Silver
River State Park near Ocala and
at the Lake Kissimmee State Park
qA east of Lake Wales. She came
to CREC in January 2003.
Amy conducts both field and laboratory work, including mite
and insect sample preparation, sorting samples, setting up tests,
monitoring trees for pests, data analysis and other computer work.
Amy is single and enjoys outdoor activities such as canoing,
camping and hiking.

likes to travel and enjoys baking.

Dr. Childers went onto North
Carolina State, where he was a
field coordinator for an apple
pest and orchard management
program. In 1977, Dr. Childers
accepted his position at CREC,
where he has established a
career in citrus acarology and
entomology.
Dr. Childers and his wife,
Lavon, have two children,


Michael and Robin, and four
grandchildren. Mrs. Childers is
an administrator for the Palm
Garden nursing home in Winter
Haven.
Dr. Childers, who says his
work is his hobby, also enjoys
saltwater and freshwater fishing,
is an avid Kansas City Chiefs fan
and loves playing with his
grandchildren.

with mite taxonomists Dr. W C.
Welbourn, Florida Department
of Agriculture & Consumer
Services in Gainesville, Dr. R.
Ochoa, USDAARS Systematic
Entomology Laboratory in
Beltsville, Dr. Barry O'Connor,
University of Michigan, and Dr.
Eddie Ueckermann, Plant Pro-
tection Research Institute in
South Africa have accelerated
these efforts.

Beneficial Mites
There are at least 100 spe-
cies of mites present on Florida
citrus with only a few being
pests. The majority are preda-
cious and feed on various other
mites and insects. An exten-
sive survey of mite species on
citrus has been on-going by Dr.
Childers since the early 1990's
and has included several sea-
son-long studies using differ-
ent pesticides, primarily fungi-
cides, at various field locations.

Threats from Citrus Leprosis
and Various Exotic Pest Mites
to Florida Citrus
Citrus leprosis is a serious
viral disease of oranges that is
vectored by one or more spe-
cies of false spider mites in the
genus Brevipalpus. The dis-
ease occurs in several coun-
tries in South America, includ-
ing Brazil. In recent years, the
disease has been increasingly
reported throughout much of
Central America. Dr. Childers,
in collaboration with Dr. Ken
Derrick, recently edited a spe-
cial issue of Experimental and

Dr. Jose Carlos Rodrigues,
in collaboration with Dr. Maria
Gallo-Meagher, UF/IFAS De-
partment of Agronomy in
Gainesville, are developing mo-
lecular methods to compare dif-
ferent populations of mites col-
lected by Dr. Childers and Dr.
Rodrigues from different coun-
tries or regions of South, Cen-
tral or North America as well as
from Australia. Parallel sets of
mite samples were also collected
for classical taxonomic compari-
sons by Dr. Ronald Ochoa,
USDAARS Systematic Entomol-
ogy Laboratory inBeltsville, and
Dr. W. C. Welbourn, Florida De-
partment of Agriculture & Con-
sumer Services in Gainesville.
The objective will be to deter-
mine if we have a previously
unidentified species complex
within one of the three currently
recognized species found on
Brazilian, Florida and Texas cit-
rus.
Dr. Childers has also identi-
fied five species of thrips that
are pests of Florida citrus.

are the largest mites.

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

Some mites cause damage to
citrus and other crops.


Dr. Jose Carlos Rodrigues
(pictured left) and Dr. Maria
Gallo-Meagher from the UF/IFAS
Agronomy Department in
SGainesville are working with Dr.
Childers to examine genetic
differences between Brevipalpus
v mite populations for identification
L and taxonomic applications.
Brevipalpus mites are vectors of
__ the citrus leprosis virus, the cause
of a serious citrus disease in Brazil and other South and Central
American countries. This research is crucial to understanding mite
populations in different regions and virus-vector relationships, and
to ultimately develop control strategies. Although citrus leprosis
virus is not currently in Florida, the Brevipalpus mite vectors do
occur in our state, and there is great concern should the virus be
introduced.


Paul Threlkeld conducted
field work for Dr. Childers as
well as some laboratory work.
He worked for Dr. Childers for
two years but is not currently
employed in the lab. His
daughter-in-law, Deanna
Threlkeld, also worked for Dr.
Childers.

Leader for development of a
Ranking System for Exotic Spe-
cies of Tetranychoidea that pose
a threat to United States agricul-
ture. Childers has served as sub-
ject editor for the International
Journal of Acarology for the past
several years and subject editor
for Arthropod Management
Tests, a publication of the Ento-
mological Society of America.
He is aboard certified entomolo-
gist since 1974 through the En-
tomological Society of America.

Depending on the species,
mites can cause fruit blem-
ishes, hurt fruit production and
damage plant parts.

Dust mites are common in
households. They are not
harmful, but many people are
allergic to them.


Rust mite feeding
damages fruit surfaces
and causes dark
blemishes called
bronzing.


Mites and ticks can carry a
number of human, animal and
plant diseases, including lyme
disease, skin mites that cause
mange and scabies, scrub
typhus, spring-summer
encephalitis and citrus
leprosis.

of Agadir on the Atlantic coast.
Morocco's citrus is grown primarily for fresh
fruit. Majorvarieties include Clementines and
other mandarins, navels, 'Salustiana' oranges and
Sanguinelli blood oranges (www.crec.ifas.ufl.edu/

Better Business
Tips that pertain to UF/IFAS Business:


Travel: Travel reimbursement vouchers
must be turned in within 10 days after
completion of travel.
Grant Closeout: When closing out a grant, keep in mind the
following:
* All encumbrances must be closed out.
* All merchandise must be receivedby the grant end date it
is not sufficient to merely commit funds by the end date.
* All invoices must be paid.
* The Final Report must be completed and a copy of the first
page submitted to Alta Church in the Business Office.
* Closeout letter issued through the IFAS Sponsored Programs
office must be signed and returned.
* Grant closeout procedures can proceed after completion of
these steps.

Paul Winniczuk, whose photo was in
last month's Citrus Leaves, is managing a
USDA grant for Dr. Mickey Parish on the
safety and security of foods transported in
tanker trucks. He is uniquely qualified to
manage this 3-year project because of his
knowledge and familiarity of protocols used
to clean and sanitize food-grade tanker
trucks. Paul conducted research for his
M.S. in Food Science in Dr. Parish's lab in
1993-94. Paul works in the Packinghouse,
Room 62. He can be reached at tel. extension

Shake, Rattle & Load
Citrus growers had an opportunity to learn more
about mechanical harvesting and abscission through
seminars and field trips. A workshop was held on
Feb. 4 in Sebring. Afield trip in the southwest Florida
area gave growers an opportunity to examine the
various mechanical harvesting systems, and a field
trip in Polk County in offered a demonstration of a
canopy shaker system (far right). Dr. Steve Futch
coordinated the event. To view speaker Powerpoint
presentations from the Feb. 4 workshop, visit:
