“…Labruna et al 2002;Olegário et al 2011;Martins et al 2012). Host specialisation of endophilic ticks, of which host range and dispersal can be expected to be low in comparison to exophilic ticks (Salman and Tarrés-Call 2012), has only been investigated in the seabird tick Ixodes uriae Dietrich et al 2013).…”

“…This suggests that these birds are the least suitable hosts for I. arboricola because moulting time of ixodid ticks is usually longer on unsuitable hosts (Labruna et al 2009;Olegário et al 2011). This is not in line with the prediction that parasites are better adapted to the most frequently encountered hosts because then the lowest success should have been found on pied flycatchers (Legros and Koella 2010).…”

“…First, parasites need to attach to a host and penetrate its skin, and attachment success is lower on unsuitable hosts . Second, once the skin is penetrated, parasites need to evade host defences, and it has been shown that blood meal duration is longer (Mccoy and Boulinier 2002;Labruna et al 2009), engorgement success lower (Labruna et al 2002;Labruna et al 2009;Dietrich et al 2013) and the blood meal smaller on unsuitable hosts (Olegário et al 2011). Finally, moulting (Labruna et al 2002;Mccoy and Boulinier 2002;Labruna et al 2009) and hatching success (Olegário et al 2011) are lower and moulting time is longer on unsuitable hosts (Labruna et al 2009;Olegário et al 2011).…”

Host specialisation in parasites can be due to either limited exposure or limited adaptation to different host types. When the first barrier is lifted experimentally, the degree of adaptive specialisation can be studied. The tree-hole tick Ixodes arboricola is an endophilic parasite with a narrow host range, found in nest boxes used mainly by great and blue tits (Parus major, Cyanistes caeruleus) and to a lesser extent by pied flycatchers (Ficedula hypoleuca) and nuthatches (Sitta europaea). In the current study, we exposed two nestlings per nestbox of pied flycatchers (N = 14), blue tits (N = 18), great tits (N = 14), and nuthatches (N = 16) to ten I. arboricola nymphs each. We found no differences in attachment success 2 days after infestation (56 ± 4% across species) nor were there any differences in tick engorgement weight (1.95 ± 0.03 mg across species), and moulting success was >90% for ticks from all bird species. Hence, our data suggest that all bird species investigated here are suitable host species. This may enhance the ticks' chances for persistence in cavities and dispersal among cavities inhabited by multiple host species, and supports the hypothesis that host use by ticks is limited by host ecology rather than by host specialisation.

“…A series of experimental studies on the life cycle or reproductive barriers of ticks have also reinforced the hypothesis. In detail, under laboratory conditions, many ticks exhibited physiological plasticity as they can feed successfully using novel hosts not related to the natural hosts (Z. Chen et al, ; Faccini, Cardoso, Onofrio, Labruna, & Barros‐Battesti, ; Labruna, Soares, Martins, Soares, & Cabrera, ; J. Liu et al, ; Ma et al, ; Olegário, Gerardi, Tsuruta, & Szabó, ; Pinter, Dias, Gennari, & Labruna, ). Meanwhile, these findings raise the possibility that the host diversity of ticks is undervalued, and various hosts can be used by ticks.…”

Ticks are obligate blood‐sucking ectoparasites, which not only directly damage through bites but also transmit many pathogens. China has a high diversity of tick species, 125 species have been reported, including 111 hard tick and 14 soft tick species. Many of the ticks are important vectors of pathogens, resulting in zoonoses. The dynamics of ticks are affected by both the host and habitat environment. However, systematic studies on the geographical distribution, host diversity, and specificity of ticks are limited in China. To achieve this goal, the relevant available data were summarized and analyzed in this study. Ticks are distributed in all parts of China and Xinjiang has the most records of ticks. The distribution of ticks in adjacent areas is similar, indicating that the habitat environment affects their distribution. Most ticks are widely distributed, whereas some species are endemic to their distributed regions. Ticks are parasitic on mammals, birds, and reptiles, of which mammals are the main host species. Overall, most ticks parasitize different hosts, only a few ticks have strict host specificity, such as ticks that are specifically parasitic on reptiles and bats. In addition, environmental changes and control efforts also influence the dynamics of ticks. These results can better reveal tick biological traits and are valuable for tick control.

“…Randolph (2004) pointed out that these factors and others such as seasonality, search time to find a host, and mortality, influence the life cycle. In this study, a temperature of 27±1 °C and relative humidity of 80±10% were used to raise A. nodosum, since these values are used to breed most Neotropical ticks (Amblyomma parvum Aragão 1908-GUGLIELMONE et al, 1991OLEGÁRIO et al, 2011;Amblyomma aureolatum -RODRIGUES et al, 2002;Amblyomma tigrinum Koch 1844-LABRUNA et al, 2002bCARDOSO et al, 2008;Amblyomma triste -LABRUNA et al, 2003;Amblyomma cooperi Nuttal;Warburton, 1908Amblyomma incisum Neumann, 1906-SZABÓ et al, 2009 -FACCINI et al, 2010;and Amblyomma ovale -MARTINS et al, 2012). However, other values for these variables may be tested to determine the best conditions for the development of this species.…”

The natural hosts of Amblyomma nodosum in the immature stages are a variety of birds and the anteater in the adult stage. However, so far no data have been published about this tick's life cycle. To fill this gap, a record was made of its development under laboratory conditions. All the procedures were controlled in a BOD chamber set at 27±1 °C and 80±10% relative humidity and scotophase. The parasitic stages were raised on rabbits (Oryctolagus cuniculus Linnaeus, 1758), from which more than 50% of larvae and nymphs were recovered, although only a small portion performed ecdysis. The adults did not fixed on the rabbits, which suggests that the experimental conditions were unsuitable for the requirements of this species. The data obtained here indicate that A. nodosum is highly dependent on its host and environment whereas under laboratory conditions and host chosen for the study was not obtained satisfactory results and new studies with different hosts and new environmental conditions should be elaborated.Keywords: Tick, host, biology, Brazil, Amblyomma nodosum. ResumoOs hospedeiros naturais de Amblyomma nodosum, nos estágios imaturos, são uma variedade de pássaros e, na fase adulta, são os tamanduás. No entanto, até agora não há dados publicados sobre o ciclo de vida desse carrapato. Para preencher essa lacuna, um registro foi realizado sobre o desenvolvimento em condições de laboratório. Todos os procedimentos foram controlados em câmaras tipo BOD a 27±1 °C e 80±10% de umidade relativa e escotofase. As fases parasitárias foram desenvolvidas em coelhos (Oryctolagus cuniculus Linnaeus, 1758), a partir dos quais mais de 50% das larvas e ninfas foram recuperados, embora apenas uma pequena porção tenha realizado ecdise. Os adultos não se fixaram nos coelhos, o que sugere que as condições experimentais eram inadequadas para os requisitos dessa espécie. Os dados obtidos indicam que A. nodosum é altamente dependente de seu hospedeiro e ambiente, enquanto em condições de laboratório e pela escolha do hospedeiro para o estudo não foram obtidos resultados satisfatórios, e novos estudos com diferentes hospedeiros e novas condições ambientais devem ser elaborados.Palavras-chave: Carrapato, hospedeiro, biologia, Brasil, Amblyomma nodosum.
