“…It has been estimated that if the disease were introduced into Florida, one of the largest beef producers in the United States, up to 50% of infected cattle and 90% of infected sheep, goats and deer would die of the disease (Burridge, 1997; Burridge et al ., 2000). Breeding colonies of the African species A. variegatum and A. marmoreum have already been found in reptile holding centres in Miami (Allan et al ., 1998). Exotic ticks have been identified on 29 (91%) of 32 reptile premises in 18 counties of Florida (Burridge et al ., 2000).…”

Aim Over the next 100 years, human-driven climate change and resulting changes in species occurrences will have global impacts on biodiversity, ecosystem function, and human health. Here we examine how climate change may affect the occurrences of tick species in Africa and alter the suitability of habitat outside Africa for African ticks.Location Africa and the world. MethodsWe predicted continental and global changes in habitat suitability for each of 73 African tick species, using multiple regression models in different climate change scenarios that cover a wide range of uncertainty. ResultsGlobal habitat suitability improves for nearly all tick species under each of a representative range of eight climate change scenarios. Depending on the scenario, African tick species experience an average increase in global habitat suitability of between 1 million and 9 million square kilometres between 1990 and 2100. Main conclusionsThe potential for successful translocations of ticks and their pathogens from Africa to the rest of the world is likely to increase over the next 100 years. Although the general trend is one of range expansion, there are winners and losers among tick species in each scenario, suggesting that tick community composition will be disrupted substantially by climate change. If this is also typical of other invertebrates, then climate change will disrupt not only the geographic location of communities but also their structure. Changes in tick communities are also likely to influence tick-borne pathogens.

“…The risk of introduction of heartwater into the United States through the international trade in live reptiles was emphasized by the results of three of our recent studies. First, we found that two of the imported reptilian tick species that have been reported to be experimental vectors of heartwater, A. marmoreum and A. sparsum , have become established in Florida,4,5 although subsequent actions have successfully eradicated the known established infestations 5. Second, we demonstrated convincingly that A. marmoreum ticks that had originated from infested reptiles on premises in Florida are competent experimental vectors of C. ruminantium 6.…”

Opportunities to introduce heartwater onto the American mainland through animal movements include importation from Africa of tick-infested reptiles and of subclinically infected wild ungulates and importation of livestock from islands in the Caribbean infested with Amblyomma variegatum ticks. Measures to control importation of heartwater vectors on reptiles include importation bans of infested species, treatment of imported reptiles, and eradication of established infestations on the American mainland. Measures to control importation of infected wildlife must focus on improved methods, such as the PCR assay, of screening animals to prevent the entry of carriers of Cowdria ruminantium. Measures to control importation of infected animals from the Caribbean must be based on knowledge of the islands that are infected with C. ruminantium so that the risk of dissemination of heartwater can be established.

“…In 1997, a leopard tortoise, Geochelone paradalis Bell, was brought to the Veterinary Medical Teaching Hospital of the University of Florida, Gainesville, FL, and ticks, identiÞed subsequently as A. marmoreum, were removed from the animal (Allan et al 1998). When the reptile breeding facility from which the tortoise originated was visited to determine if it was infested with the tick, a total of 443 A. marmoreum was collected from tortoises (53.3%), dogs (1.1%), and vegetation (45.6%).…”

“…Other transport hosts of exotic arthropods include the elephant, Elephas maximus L., cheetah, Acinonyx jubatus (Schreber), sloths, antelopes of several species, and a bat-eared fox, Otocyon megalotis (Demarest). Imported reptiles, which have not been regulated, have also served as hosts for the introduction and establishment of exotic arthropods (Allan et al 1998).…”

Introduction of Nonindigenous Arthropod Pests of Animals

A variety of pathways exist for the introduction of nonindigenous insects, ticks, and mites of veterinary importance into the United States. The most prominent includes the natural migration of mosquitoes and flies by the flight of adults, ectoparasites entering the country on wildlife transport hosts, and accidental introductions on animals legally imported through United States Department of Agriculture (USDA) quarantine facilities. Examples of the establishment and subsequent eradication of exotic pests of livestock are presented to illustrate the critical role of the USDA in protecting American agriculture with particular emphasis on the southern cattle tick, Boophilus microplus (Canestrini), the cattle tick, B. annulatus (Say), and the screwworm, Cochliomyia hominivorax (Coquerel). Priority group rating of nonindigenous arthropod pests and disease vectors are discussed. Although the primary responsibility for preventing the introduction and establishment of arthropods that affect livestock and poultry rests on the shoulders of USDA professionals, insect surveys by extension entomologists along with observations by research specialists and producers are also important in detecting exotic arthropod species. Animal health professionals from all sectors of the livestock and poultry industries may well be the first line of defense from the introduction of nonindigenous arthropods and the diseases they transmit.
