Ixodidae
The Ixodidae are the family of hard ticks or scale ticks, one of the three families of ticks, consisting of 771 species, . They are known as 'hard ticks' because they have a scutum or hard shield, which the other major family of ticks, the 'soft ticks' (Argasidae), lack. They are ectoparasites of a wide range of host species, and some are vectors of pathogens that can cause human disease. Description They are distinguished from the Argasidae by the presence of a scutum. In both the nymph and the adult, a prominent gnathosoma (or capitulum, mouth and feeding parts) projects forward from the animal's body; in the Argasidae, conversely, the gnathosoma is concealed beneath the body. They differ, too, in their lifecycle; Ixodidae that attach to a host bite painlessly and are generally unnoticed, and they remain in place until they engorge and are ready to change their skin; this process may take days or weeks. Some species drop off the host to moult in a safe place, whereas others ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tick
Ticks are parasitic arachnids of the order Ixodida. They are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, and species, but can become larger when engorged. Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are around 100 million years old, and come from the Cretaceous period. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families: the Ixodidae, or hard ticks, and the Argasidae, or soft ticks. '' Nuttalliella'', a genus of tick from southern Africa, is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalotho ...

Ixodes
''Ixodes'' is a genus of hard-bodied ticks (family Ixodidae). It includes important disease vectors of animals and humans ( tick-borne disease), and some species (notably '' Ixodes holocyclus'') inject toxins that can cause paralysis. Some ticks in this genus may transmit the pathogenic bacterium '' Borrelia burgdorferi'' responsible for causing Lyme disease. Additional organisms that may be transmitted by ''Ixodes'' are parasites from the genus '' Babesia'', which cause babesiosis, and bacteria from the related genus '' Anaplasma'', which cause anaplasmosis. Species These species are recognised within the genus ''Ixodes'': *'' Ixodes abrocomae'' Lahille, 1916 *'' Ixodes acer'' Apanaskevich & Schenk, 2020 *'' Ixodes acuminatus'' Neumann, 1901 *'' Ixodes acutitarsus'' (Karsch, 1880) *'' Ixodes affinis'' Neumann, 1899 *'' Ixodes albignaci'' Uilenberg & Hoogstraal, 1969 *'' Ixodes alluaudi'' Neumann, 1913 *'' Ixodes amarali'' Fonseca, 1935 *'' Ixodes amersoni'' Kohls, 1966 ...

Dermacentor
''Dermacentor'' is a genus of ticks in the family Ixodidae, the hard ticks. The genus has a cosmopolitan distribution, with native species on all continents except Australia. Most are found in North America. Hosts of ''Dermacentor'' ticks include many large and small mammals, including horses, deer, cattle, lagomorphs, peccaries, porcupines, tapirs, desert bighorn sheep, and humans. The American dog tick (''D. variabilis'') is a member of the genus. ''Dermacentor'' species are vectors of many pathogens, including '' Rickettsia rickettsii'', which causes the disease Rocky Mountain spotted fever, ''Coxiella burnetii'', which causes Q fever, '' Anaplasma marginale'', which causes anaplasmosis in cattle, '' Francisella tularensis'', which causes tularemia, ''Babesia caballi'', which causes equine piroplasmosis, and the '' Flavivirus'' that causes Powassan encephalitis. ''Dermacentor'' ticks inject a neurotoxin that causes tick paralysis. Species As of 2019, about 41 speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bothriocroton
''Bothriocroton'' is a genus of hard ticks. There are seven extant member species, native to Australia and Papua New Guinea. ''Bothriocroton'' species typically parasitise monotremes, marsupials, and reptiles. ''Bothriocroton'' ticks have a limited pathogenic profile. ''Bothriocroton hydrosauri'' (Southern reptile tick), is a vector of '' Rickettsia honei'', the causative bacteria of Flinders Island spotted fever. '' Bothriocroton concolor'' (echidna tick) carries ''Borrelia tachyglossi,'' but the bacterium is phylogenetically distinct from Lyme disease ''Borrelia'', and has not been shown to be pathogenic to humans. Similar reptile-associated ''Borrelia'' are found in ''Bothriocroton undatum.'' Description ''Bothriocroton'' are large (2-7mm), round ticks. Their mouthparts are long, with lateral palpal margins narrower than their basis capitulum. They are further characterised by a posterior anal groove, and absence of sclerotised adanal plates. They have no eyes. The reporte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amblyomma
''Amblyomma'' is a genus of hard ticks. Some are disease vectors, for example the Rocky Mountain spotted fever in United States or ehrlichiosis in Brazil. This genus is the third largest in the family Ixodidae, with its species primarily occupying the torrid zones of all the continents. The centre of species diversity is on the American continent, where half of all the species occur. On this continent, ''Amblyomma'' species reach far beyond the torrid zone, up to the 40th parallel in the Northern Hemisphere, to the 50th parallel in the Southern Hemisphere, and even reaches the alpine zone of the Andes. They also occur in Eurasia, Africa and Australia. G. V.

Archaeocroton
''Archaeocroton sphenodonti'', or the tuatara tick, is a species of tick that parasitises only the tuatara of New Zealand. It is found on just four of the twelve island groups where tuatara survive, preferring islands where the reptiles live in high densities. Larvae, nymphs, and adults all feed exclusively on tuatara blood, and ticks can survive for up to a year without a host. When tuatara are translocated, the tick has been lost or survives only in low densities in the new population. It is the only living species in the genus ''Archaeocroton''. Description Adult tuatara ticks are nearly circular, light brown and long. They were first described by Lionel Jack Dumbleton in 1943. The holotype male specimen was collected from Stephens Island by E. J. Tillyard in January 1922 and later deposited in the New Zealand Arthropod Collection. Taxonomy Originally, this species was placed in the genus ''Aponomma'', as members of this genus mostly parasitise reptiles. More primitive ...

Cosmiomma
''Cosmiomma'' is a genus of ticks first discovered by Paul Schulze in 1919. Paul Schulze. 1919. Bestimmungstabelle für das Zeckengenus ''Hyalomma'', Koch. ''Sitzungsberichte der Gesellschaft Naturforschender Freunde zu Berlin'', 5:189–196, http://biostor.org/reference/127288, last accessed 24 Jun 2019. It is monospecific, being represented by the single species ''Cosmiomma hippopotamensis''. It was first described in 1843 by Henry Denny from specimens collected from a hippopotamus in Southern Africa, and has been called "one of the most unusual, beautiful, and rare tick species known to the world." Taxonomy and systematics The taxonomic position of the genus ''Cosmiomma'' has been unstable since the male and female of the type species were first described as two separate species. As late as 1997, two published studies based on the type species' morphology concluded separately that ''Cosmiomma'' was most closely related to '' Rhipicephalus'' species ticks and that ''Cosmiomma' ...

Argasidae
The Argasidae are the family of soft ticks, one of the three families of ticks. The family contains 193 species, although the composition of the genera is less certain, and more study is needed before the genera can become stable. The currently accepted genera are '' Antricola'', '' Argas'', '' Nothoaspis'', ''Ornithodoros'', and '' Otobius''. The Argasidae are very common in South Asia, along with 96 other species of ticks, making South Asia the region with the highest biodiversity of ticks worldwide. Soft ticks are resistant to desiccation and can live for several years in arid Aridity is the condition of geographical regions which make up approximately 43% of total global available land area, characterized by low annual precipitation, increased temperatures, and limited water availability.Perez-Aguilar, L.
