Biologia da fase parasitária de Anocentor nitens (Neumann, 1897) (Acarina: Ixodidae)

Abstract

The biology of Anocentor nitens was studies in experimental infestation at rabbit and cow host. The methodology to infested host was Amblyomma cajennense likes used by SERRA FREIRE (1984). TO rabbit and cow were used 3.000 larvae and 6.000 lar vae of A. nitens, respectively. At the both host the tick showed a cycle like one host ("monoxeno") and two host development ("heteroxeno"). The mean weight of young male ("neandro") was 2,7 mg and young female ("neógina") was 2,5 mg to "heteroxeno" cycle at rabbit and cow; 1,79 and 2,34 mg respectively. There were no confirmated the hight specificity of A. nitens by inner side of ears horse host. The were observed the periods of: pre-fed, engorgement, pre-molt of larvae, nymphs and adults, and molting of pos-fed larvae ("metalarva") to young nymphs ("neoninfa"), pos-fed nymph ("metaninfa") to young male or young female, xiv. to both "monoxeno" and "heteroxeno" cycle and the both host. The mean weight of young nymphs was 0,12 mg to ticks from cow and 0,49 mg to ticks from rabbit to "heteroxeno" cycle.
