    Abstract:
    This study evaluates the impact of cattle-raising on ticks associated with wildlife in the Pantanal region of Brazil, by trapping free-living ticks using a CO(2) tick trap. The traps were equally distributed in two areas: a 600-ha protected area (PA) and the Nhumirim Ranch (NR). Both areas are contiguous and located at the sub-region of Nhecolândia (18 degrees 59'S; 56 degrees 39'W), Pantanal, Brazil. In each area, four habitat types were selected: cerrado (tropical savanna), forest patches, lakes and soda lakes. The last two are temporary lagoons of fresh and salted water, respectively. A total of 980 nymphs, 613 adults and 13 larvae of ticks Amblyomma were collected in 256 h of collection. In a pen of calves infested by Ornithodoros rostratus 114 specimens were collected, including larvae, nymphs and adults. Adults of A. cajennense and A. parvum were more abundant in the savanna at NR, but not differed among habitat types at PA. There was a tendency of having more nymphs in NR than in PA. The higher number of ticks found in the NR in comparison to the PA is not due to the presence of cattle itself but probably due to introduced dogs and horses, habitat alteration.
