New CREC Measures To Prevent

Spread of Root Weevil

Precautions For All Personnel; Spring Critical Time

Preventing the spread of the Diaprepes root
weev il and citrus canker was the top issue dis-
cussed at a CREC Cenrerv ide staff meeting on
April 25. The Diaprepes root weevil, a deadly
pest of citrus, ornamentals and several other
crops, has infested CREC groves.
In April, Dr. Pete Timmer issued a centerwide
memorandum that outlined stringent measures
to be followed by all personnel to prevent the
spread of the Diaprepes root weevil (see next
"We have immediate need to make sure we
don't move [Diaprepes]." said Dr. Harold Brown-
ing, Center Direclor. "The industry is challeng-
ing us not to move it into their groves. We have
to be sure we're making every effort not to move

of adult insects typically occurs during this time

A centerwide memorandum outlini g Diaprepes
measures is posted on the bulletin board out-
side the Mailroom. Personnel are also reminded
that canker disinfection/decontamination mea-
sures are still in effect If canker were to be
found on or near Center property a mandatory
eradication or our citrus trees would be devas-
tating loss for our research programs.

To prevent spread of root weevils:

1) Nursern trees, plant material, and soil should
not be taken off station to other citrus groves.
If it is necessary to move nursery trees, they
should be bare-rooted and washed to remove
larvae and the tops trimmed back and the trees
inspected for adults and egg masses.
2) All casual vegetative material and soil should
be removed from the vehicles before leaving
the station.
3) If you have been in station groves, you
should hose down vehicles or visually check
the outside, especially the grill for -oot weevils.

Congressman Putnam at CREC
U.S. Representative Adam Putnam ( District 14) held a Lake
A if red town meeting at CREC on April 11. Putnam addressed
issues such as agriculture, energy, taxes, education and
government reform. Acrowd of35 people, including local
residents, CREC personnel and local citrus growers, had the
-o opportunity to speak to Putnam before and after the meeting.
Putnam represents District 12 in the U.S. House of Repre-
sentatives, which includes much of Polk county, all of DeSoto
and Hardee counties, and protions of Hillsborough. Pasco
and Highlands counties. Elected to Congress in Noseniber,
he is also involved in his family's citrus and cattle business.

coffee bean grinder, and Nematology.

Dr. Knapp (left) chats with Mike Armstrong. Dr. Knapp's career highlights include
serving as Editor of the Citrus Pest Mangement Guide, the most widely sold L F
II [FAS document in print. Dr. Knapp provided advice to growers and production
managers in Florida and around the world on pest management problems. He also
carried out important field research on IPM materials. He brought growers, scien-
tists and regulator personnel together to battle pests such as citrus leaf miner,
Diaprepes, brown citrus aphid and Medfly. "It hasn't lacked for excitement and new
challenges." said Dr. Knapp. speaking of the invasion of numerous citrus pests and
pathogens during his career.

larvae also feed on the roots. leaving the
tree vulnerable to fungal infection by
Phytophthora. The combination of
Diaprepes and PhYitophlthor is devas-
tating, causing a rapid decline in tree
Dr. Browning pointed out that current
pest management measures will only sup-
press the insect populations, but do not
eradicate the pest.
"Please don't be responsible for mov-
ing the weevil off the Center," said Dr.
Browning, who pointed out that
Diaprepes precautions are not all that dif-
ferent from the mandatory measures cur-
rently in effect for citrus canker.
Other highlights from the Centerwide
meeting can be found on pages 4 and 5.

How Is Diaprepes Spread?

Tiny larvae, eggs hard to detect;
No movement of potted plants off CREC allowed

Native to the Caribbean, the Diaprepes root weevil (Diaprepes abbrevialus) was
first detected in Apopka in the 1960's. It is now spread throughout all citrus grrow ing
regions in Florida, and was recently detected in Texas.
While adult insects can fly and migrate short distances, long-distance movement of
Diaprepes has been facilitated by man. Moving pots of citrus from one location to
another is one of the "easiest" ways to transport Diaprepes. Newly-hatched larvae are
tiny, only 1-2 mm in length, and near impossible to detect in the soil. Eggs, typically
"sandwiched" between two leaf surfaces, are also difficult to spot without careful
For these reasons. the movement of potted plants off CREC is not allowed. If it is
necessary to move nursery trees, they should be bare-rooted and washed to remove
larvae, the tops trimmed back and the trees inspected for adults and egg masses (see
Diaprepes measures, page 1).

Diaprepes Task Force Focuses On

Education, Communication

Meeting May 10 in Homestead
The Diaprepes Task Force, led by Bartow grower
Garvie Hall, is a group of citrus growers, regulatory
personnel and researchers that works to educate and
inform citrus growers about the Diaprepes root weevil.
The Diaprepes Task Force also plays an active role in
promoting research and finding ways to improve pest
The next Diaprepes Task Force meeting is May 10 in
Homestead and is open to all interested persons. The
meeting will focus on the Diaprepes problem in other
Florida crops besides citrus.

Several Labs Involved in

Diaprepes Research

Pest Management A Priority

CREC's mulit-disciplinary efforts are focused on both short- and
long-term measures for Diaprepes root weevil management. Its
wide host range (over 250 known species), biology and other
factors make this one of the most difficult challenges facing the
citrus industry. Below is a list of CREC faculty and their laborato-
ries involved in Diaprepes research. Other UF [FAS REC's. USDA
and other agencies are also engaged in the war against Diaprepes.
* Dr. Clay McCoy: Integrated pest management, chemical and non-
chemical measures, root weevil biology.
* Dr. Herb Nigg: Root weevil biology and reproduction, methods
to trap and assess root weevil populations.
* Dr. Larry Duncan: parasitic nematodes as a biological control for
Diaprepes root weevil larvae.
* Dr. Jim Graham: Interaction between Phythophthora and
Diaprepes, short-term (chemical treatments) and long-term

UF/IFAS Center in Homestead Loses

Citrus Trees in Canker Eradication

CREC Personnel Urged to Follow Canker Regulations

Dr. Harold Browning urged CREC Personnel
to follow the citrus canker disinfection/
decontamination measures in effect through-
out Florida (see box, right)
The state is currently fighting citrus
canker in seven counties: Dade & Broward,
Palm Beach, Manatee, Hillsborough, Collier
and Hendry Infected trees and exposed
trees within 1900 feet are destroyed by the
Florida Citrus Canker Eradication Program
As of April 20, almost 2 million trees have

been destroyed, including over a million
trees in commercial groves.
Citrus canker was recently detected at the
UF/IFAS Tropical Research and Education
Center in Homestead. Over a thousand trees
on their property were destroyed.
Dr. Browning asked the staff to think
about the grim consequences of finding
canker at CREC "We'd have to remove all of
our trees." he said. To date, citrus canker
has not been detected in Polk County.

More News From the Centerwide Staff Meeting
