reproductive interactions between two australian reptile tick species.in south australia the two tick species amblyomma limbatum and aponomma hydrosauri share the same common reptile host species, but have allopatric distributions which abut along a narrow parapatric boundary. reproductive interference is a mechanism that has previously been suggested could contribute to maintaining the boundary. populations of each species were established in pens within the range of aponomma hydrosauri. pens held either each species alone, or the two species together. the perfor ...19947628259
range expansion of the tick amblyomma triguttatum triguttatum, an australian vector of q fever.the tick amblyomma triguttatum triguttatum has previously been reported from western australia, queensland and new south wales. a viable population of this species, including all developmental stages, has now been discovered on the southern end of yorke peninsula, south australia. species determination was carried out morphologically and using 18s and 16s rrna. the data for 16s rrna are the first published for this species. amblyomma t. triguttatum is significant through its involvement in the n ...200010899523
prevalence and intensity of the blood parasite hemolivia mariae in a field population of the skink tiliqua rugosa.the impacts of virulent parasites on humans or domestic animals are well documented. less is known of the impact of parasites in natural host-parasite associations. a population of the australian sleepy lizard tiliqua rugosa is infected with the blood microparasite hemolivia mariae, which is transmitted by the ectoparasitic tick amblyomma limbatum. in most infected lizards a very small proportion, usually < 1%, of red blood cells are infected. a study of the prevalence of the microparasite in th ...200010952265
influence of temperature and relative humidity on the moulting success of amblyomma limbatum and aponomma hydrosauri (acari: ixodidae) larvae and nymphs.this study compared the duration of the moulting periods of engorged larvae and nymphs of the ixodid ticks, amblyomma limbatum and aponomma hydrosauri, at different temperature/relative humidity regimes, and examined the relationships between the engorged weight of ticks and their weights after moulting. the results showed that for each species, there was a significant relationship between the weights of unfed nymphs and engorged larvae, and the weights of unfed adults and engorged nymphs. the w ...200010980285
temporal and spatial dynamics of a parapatric boundary between two australian reptile ticks.two tick species aponomma hydrosauri and amblyomma limbatum that infest large reptiles have an abrupt parapatric boundary near mt mary in south australia. a previous model has suggested that the boundary is maintained at population density troughs resulting from habitat heterogeneity along a gradual environmental gradient. this paper describes the dynamics of the boundary on three transects over 17 years, 1982-98. over the last seven years of that period there has been a significant increase in ...200111298975
seasonal density fluctuations of the exotic ornate kangaroo tick, amblyomma triguttatum triguttatum koch, and its distribution on yorke peninsula, south australia.the ornate kangaroo tick, amblyomma triguttatum triguttatum, was recently recorded on southern yorke peninsula, south australia. we examined seasonal fluctuations in a. triguttatum triguttatum life stages (adult, larva, and nymph) and its distribution on the peninsula. we used in situ co2 traps and dragging cloths to determine monthly fluctuations in free-living ticks at four sites at innes national park from january to december 2006, and to determine the tick's distribution on wider yorke penin ...200717587053
hosts of the exotic ornate kangaroo tick, amblyomma triguttatum triguttatum koch, on southern yorke peninsula, south australia.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 ide ...200717611781
human perception and awareness of ticks in a south australian rural community and implications for management of amblyomma triguttatum triguttatum.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 ...200818427936
