host detection by four australian tick species. | the behavior of 4 tick species in the presence of their dominant host species was examined. nymphs and adult ticks could locate a host from greater distances than the larvae. adult aponomma concolor were able to locate their mammalian host (echidna) from distances greater than 3 reptile-infesting species could locate their hosts. the results suggested that all 4 tick species detect hosts passively, which may be related to the relative scarcity of hosts and their irregular use of refuge sites. | 1991 | 2040944 |
[the coevolution of ixodid ticks and terrestrial vertebrates]. | paleontologic and zoogeographic data speak in favour of mesozoic origin of ixodid ticks. the absence of strict restrictions for the feeding on unusual species of hosts has caused the domination of polyphagy and oligophagy over monophagy among ixodid ticks. the same peculiarities of ixodid ecology are responsible for a restricted part or absence of phylogenetic parallelism with hosts in their evolution. primary food relations with reptiles are, apparently, preserved only in the genus aponomma and ... | 1989 | 2694077 |
