Influência do hospedeiro no ciclo e comprovação do ciclo heteroxeno de Anocentor nitens (Neumann, 1897)

Host influency on life cycle and comprovation of the heteroxenous cycle of Anocentor nitens (Neumann, 1897)

Resumo

Steers and rabbits were used as experimental hosts for Anocenter nitens during scheduled infections, when ticks were recovered from naturally infected horses. Thus, the influence of the host species on the parasite was evaluated mainly considering parameters related to the engorgement period and pre molting of evolutive stages. It was also observed that almost 5% if the metanymphae and a few more than 1% of metalarvae fall off from the host to molt in the evironment, characterizing cycles in one or more hosts. The heteroxenous cycle is reported for the first time occuring in A. nitens.
