Successful Infestation by Amblyomma pseudoconcolor and A. cooperi (Acari: Ixodidae) on Horses

Abstract

The host relationships for most species of the genus Amblyomma are poorly known in Brazil. The ability of A. pseudoconcolor and A. cooperi to successfully feed on horses was investigated during ongoing research on the life cycle of these two species, which are primarily associated with wildlife. Results of these experiments suggest that horses are potential hosts for the adult stages of both species.

A meta-analysis of host specificity in Neotropical hard ticks (Acari: Ixodidae)

“…Hosts, such as rabbits ( Oryctolagus cuniculus ), guinea pigs ( Cavia porcellus ), chickens ( Gallus gallus ), rats (Rattus norvegicus ), mice ( Mus musculus ), dogs ( Canis familiaris ), domestic pigs ( Sus scrofa ), horses ( Equus caballus ), among others, were successfully utilized to feed a wide spectrum of ticks under laboratory conditions. Some examples of this type of study in Neotropical hard ticks include the life cycle of Amblyomma auricularium, Amblyomma incisum, A. triste, A. tigrinum, A. aureolatum, A. parvum, A. neumanni, Amblyomma brasiliense, Amblyomma pseudoconcolor, Haemaphysalis leporispalustris and I. loricatus (Guglielmone et al ., 1991; Aguirre et al ., 1999; Labruna et al ., 2000, 2002, 2003; Schumaker et al ., 2000; Chacon et al ., 2004; Pinter et al ., 2004; Sanches et al ., 2008; Szabó et al ., 2009; Faccini et al ., 2010; Olegário et al ., 2011). Cross-mating trials to elucidate reproductive barriers between Amblyomma pseudoparvum and A. parvum , and among the members of the Amblyomma cajennense species complex, were carried out using rabbits as hosts (Guglielmone & Mangold, 1993; Labruna et al ., 2011; Mastropaolo et al ., 2011).…”

Biology and life cycle of Amblyomma incisum (Acari: Ixodidae)

“…1 Engorged and unfed Amblyomma incisum female of 27°C, 85% RH, and a photoperiod regimen 00:24 (light:darkenss). Although different laboratory conditions and host species used in other studies should be taken into account, generally the mean engorged female weight was the highest and pre-oviposition and incubation periods were the longest when compared to other Neotropical Amblyomma species studied so far (mostly under 27°C likely the present study), such as Amblyomma aureolatum (Pallas) (Rodrigues et al 2002;Pinter et al 2004); A. cajennense Castagnolli et al 2003;Chacon et al 2004); Amblyomma brasiliense (Sanches et al 2008) Amblyomma dubitatum Neumann (Chacon et al 2004;Labruna et al 2004); Amblyomma parvum Aragão (Guglielmone et al 1991); Amblyomma pseudoconcolor Aragão (Chacon et al 2004); Amblyomma tigrinum Koch (Labruna et al 2002), and Amblyomma triste Koch (Labruna et al 2003). At the same time, mean EPE and egg hatching rate were very low, suggesting inappropriate off-host conditions for A. incisum species in the laboratory.…”
