At least 71 species of ticks occur in Australia; a further 33 or so species are endemic to its neighbours, New Guinea and New Zealand. The ticks of Australia and other parts of Australasia are phylogenetically distinct. Indeed, there are at least two lineages of ticks that are unique to Australasia: the genus Bothriocroton Klompen, Dobson & Barker, 2002; and the new genus Archaeocroton Barker & Burger, 2018. Two species of ticks that are endemic to Australia are notorious for feeding on humans: (i) Ixodes holocyclus, the eastern paralysis tick, in eastern Australia; and (ii) Amblyomma triguttatum triguttatum, the ornate kangaroo tick, in Western Australia, at one place in South Australia, and in parts of Queensland. Three of the other endemic species of ticks that feed on humans in Australia are also noteworthy: (i) Bothriocroton hydrosauri, the southern reptile tick, which is a vector of Rickettsia honei (Flinders Island spotted fever); (ii) Haemaphysalis novaeguineae, the New Guinea haemaphysalid; and (iii) Ornithodoros capensis, the seabird soft tick. Here, we present images of female Ixodes holocyclus, Amblyomma t. triguttatum, Bothriocroton hydrosauri and Haemaphysalis novaeguineae and our latest maps of the geographic distributions of Ixodes holocyclus, Amblyomma t. triguttatum and Bothriocroton hydrosauri. None of the five exotic species of ticks in Australia typically feed on humans.

“…It is unclear to what extent the species has colonised wider Yorke Peninsula. A. t. triguttatum parasitises a variety of mammalian hosts, including humans (Guglielmone 1990;) and the species is endemic to much of Queensland (excluding Cape York Peninsula), inland eastern Australia, and south-west Western Australia (including Barrow Island). In Queensland, A. t. triguttatum is implicated in the epidemiology of Q fever (Guglielmone and Moorhouse 1986;McDiarmid et al 2000).…”

Human perception and awareness of ticks in a South Australian rural community and implications for management of Amblyomma triguttatum triguttatum

2008

The ornate kangaroo tick, Amblyomma triguttatum triguttatum, is invasive on Yorke Peninsula, South Australia. To assess the potential for developing comprehensive management strategies for the species, we mailed 1,000 surveys to Yorke Peninsula residents to investigate community perceptions of ticks, gather information on tick-host ecology, and assess whether or not occupation and length of residence affected whether residents had seen ticks. The response rate was 32%; most respondents (63%) had not seen ticks on Yorke Peninsula. Of those who had (n = 104), 56% had seen ticks on animals, especially lizards (31%) and kangaroos (20%); 50% had seen ticks on humans. Of the 64 respondents who believed places on Yorke Peninsula had many ticks, 56% identified Innes National Park and 75% areas on southern Yorke Peninsula. The likelihood of seeing ticks was not related to occupation. Whether respondents had seen ticks was related to length of residence on Yorke Peninsula (<10 years = 23.6%, 10-30 years = 44.0%, 31-50 years = 47.6%, 51-70 years = 30.9%, 71+ years = 21.4%). The number of respondents who had seen ticks on humans suggests that tick-borne diseases could become a public health issue on Yorke Peninsula. This finding is of particular concern because A. t. triguttatum is implicated in the epidemiology of Q fever in Queensland. Finally, respondents were unaware of the responsibility for tick management, which demonstrates a need for collaboration amongst stakeholders.

“…In humans, Q fever generally presents acute flu-like symptoms, although heart failure may also occur occasionally. In approximately Roberts (1962); Guglielmone (1990) 10% of cases, long-term chronic fatigue-type symptoms may also surface (Maurin and Raoult 1999;McDiarmid et al 2000;Arricau-Bouvery and Rodolakis 2005). It is unknown whether the Yorke Peninsula population of A. triguttatum triguttatum retains Coxiella burnetii, although the potential for a full Q fever cycle (transmission of Coxiella burnetii between ticks, kangaroos, and sheep) exists because the park is habitat to a known host species, the western grey kangaroo, and is bordered by pastoral properties (McDiarmid et al 2000).…”

Hosts of the exotic ornate kangaroo tick, Amblyomma triguttatum triguttatum Koch, on southern Yorke Peninsula, South Australia

et al. 2007

Amblyomma triguttatum triguttatum is assumed to be endemic to south-western Western Australia (including Barrow Island), Queensland (excluding Cape York Peninsula), and New South Wales, south to Dubbo and Barham. The species has been recorded on a range of mammalian hosts including macropods and domestic animals. In Queensland, A. triguttatum triguttatum is implicated in the epidemiology of Q fever. In 2000, the species was detected on southern Yorke Peninsula in South Australia. We aimed to identify A. triguttatum triguttatum's hosts through trapping, sampling of carcasses, and opportunistic capture of vertebrates on Yorke Peninsula. A. triguttatum triguttatum was removed from black rats (Rattus rattus), wild rabbits (Oryctolagus cuniculus), western grey kangaroos (Macropus fuliginosus), Tammar wallabies (M. eugenii eugenii), domesticated cats and dogs, and humans. Before this study, A. triguttatum triguttatum had not been found on black rats or rabbits in the wild. This research has implications for the management of wildlife, livestock, and visitors on Yorke Peninsula. The potential for A. triguttatum triguttatum to spread to other areas of Yorke Peninsula and South Australia is considerable, as visitors (tourists) to southern Yorke Peninsula report the presence of ticks both on themselves and among camping equipment on arriving home.
