From what I understand, many more species of ticks have been introduced into Florida than what is noted here....
And some have moved right along over the years.... and have been found as far west as Texas and as far north as up thru Georgia, NC, SC and Virginia.
They're EVERYWHERE! They're EVERYWHERE!
"...10 exotic tick species have been imported into Florida on reptiles.."
"Some of these tick species can transmit disease agents of animal or public health significance.."

INTRODUCTION OF THE EXOTIC TICK
AMBLYOMMA CHABAUDI RAGEAU (ACARI: IXODIDAE) INTO FLORIDA ON IMPORTED TORTOISES

International trade in live reptiles has been ongoing for many years, with the pet trade com- ponent of this enterprise a significant end-user of live tortoises, turtles, lizards and snakes (Roth & Merz 1997).
In the United States, the pet trade is responsible for more than 80% of the total world trade in reptiles (Hoover 1998).
Many of these reptiles enter the United States through Florida.
Studies conducted by the University of Florida between 1997 and 1999 showed that 10 exotic tick species have been imported into Florida on reptiles (Burridge et al. 2000, Simmons & Burridge 2000), including six species of Amblyomma and four species of Aponomma.
Some of these tick species can transmit disease agents of animal or public health significance (Burridge 2001) and, thus, research is underway in the authors' laboratory to define measures to minimize the introduction and spread of exotic ticks.
Recently, we detected yet another exotic tick species, Amblyomma chabaudi Rageau, that has been introduced into Florida on imported tortoises.
Details of this introduction are described herein.
In collaboration with the Florida Fish and Wildlife Conservation Commission, the authors initiated studies of reptiles recently imported into Florida through the Miami International Airport. One such shipment involved 125 spider tortoises (Pyxis arachnoides) imported from Madagascar to a reptile dealer in South Florida.
Nineteen of the tortoises were infested with 23 adult ticks, 21 and 2 of which were attached to the rear and front legs, respectively. All ticks were identified as male Amblyomma chabaudi Rageau.
Sample specimens were submitted to the National Veterinary Services Laboratory in Ames, Iowa, for species confirmation, with accession No. 95109.
This is the first report of A. chabaudi in the United States and the first report of this tick outside of Madagascar.
Amblyomma chabaudi was first described in 1963 infesting a spider tortoise in Madagascar (Rageau 1964). Since that time, three publications regarding this species (Uilenberg 1965, 1967, Uilenberg et al. 1979) have shown A. chabaudi distributed only in southern Madagascar and have indicated a limited host range.
All published records of A. chabaudi are from spider tortoises, except for one male on a radiated tortoise (Geochelone radiata) (Uilenberg et al. 1979), with both tortoise species limited in natural distribution to Madagascar (Alderton 1988).
However, Uilenberg (1967) was able to feed A. chabaudi in the laboratory on radiated tortoises, Madagascar flat-shelled tortoises (Pyxis planicauda) and rabbits. Thus, in the absence of its preferred host, the spider tortoise, A. chabaudi could infest other host species.
Nothing is known of the potential of A. chabaudi to transmit diseases or regarding its potential environmental impact in Florida.
The work described in this report was supported by U.S. Department of Agriculture Tropical/Subtropical Agricultural Research grant no. 00-34135-9814.
The authors are grateful to James Mertins of the U.S. Department of Agriculture in Ames, Iowa, for confirmation of the identity of these exotic ticks found in Florida and to Lieutenant Patrick Reynolds of the Florida Fish & Wild- life Conservation Commission for assistance with access to the premises of the reptile importer.
SUMMARY
This is the first report of the ixodid tick, Amblyomma chabaudi Rageau, in the United States.
It was introduced into the United States on spider tortoises (Pyxis arachnoides ) imported from Madagascar to a reptile dealer in Florida. Infor- mation on the few published reports on this exotic tick is reviewed.
