In January 1972, six A. variegatum ticks were collected from goats and sheep on two premises 
on_St: Croix 
The aerial spraying was planned and conducted by Special Operations Force, U.S. Department 
of the Air Force, Eglin Air Force Base, Fla. Sevin was sprayed from jeeps carrying the spraying 
equipment or from aircraft, depending on terrain. Spraying was completed in December 1968. 
The last collection of A. variegatum from livestock on a farm had been in April 1968. The 
survey of St. Croix in May 1969 revealed no A. variegatum ticks, and overall results were 
encouraging. However, on August 7, 1969, a single male tick was found at the slaughterhouse on a 
bull from the eastern part of the island; the six previously infested premises were on the western 
end. Inspections of livestock on the farm of origin of the bull and on other farms in that area did 
not disclose any additional A. variegatum ticks. 
Systematic dipping was discontinued on each farm 2 years following the most recent collection 
of A. variegatum on the farm, and thus all systematic dipping was discontinued in May 1970. In 
May 1972, a complete inspection of livestock on St. Croix was made and no A. variegatum ticks 
were found. 
On March 17, 1971, a Consumer and Marketing Service (C&MS) meat inspector collected a 
male A. variegatum tick from a sheep at the local abattoir. A complete inspection at the farm of 
origin disclosed additional A. variegatum on sheep and cattle. This premises is under insular 
quarantine and systematic dipping was instituted.

Tick Eradication Training School 
A tick eradication training school was held at Laredo, Tex., April 24-28, 1972. There were 
nine participants from the Veterinary Services station in Austin, Tex., and nine from the Texas 
Animal Health Commission. This brings the total number of persons receiving such training to 256. 
The majority of these people were actively engaged in tick eradication activities along the Rio 
Grande River and in the South Texas areas.
