CONDORI, Ronald et al. Relative frequency of Boophilus microplus (Canestrini 1888) & Amblyomma cajennense (Fabricius 1787) (Acari: Ixodes) in cattle in Yucumo colonization area, General José Province Ballivián Beni, Bolivia. J. Selva Andina Res. Soc. [online]. 2010, vol.1, n.1, pp.13-22. ISSN 2072-9294.

The study on the relative abundance of Amblyomma Boophilus microplus & cajennense was conducted in 32 colonies, divided into two ecological zones (ZE) and two rainfall regimes in the area of Yucumo, Beni, Bolivia. Visits were made every twenty day to collect mite of cattle population using the method of demolition. The total number of mite was considered, the total number of ectoparasites sampled from each animal and all animals were added to each colony sampled, the value of each animal was divided it between all the animals of each colony to determine the average number of ticks per colony. Was detected B. microplus in all the colonies, during the months of May to October (2008). Statistical analysis was done for comparison of means and no differences were found between ZE, colonies for Boophilus microplus, Amblyomma cajennense as is found in association with the Boophilus microplus on the prairie. Although there were no differences between production systems, it emphasizes that the relative frequency of infestation of cattle in the ZE studied is very similar except for the colony August 6 ZE corresponding to the ridge which has elevated mite per animal. The need is to develop work which show the diversity of this important group of arthropods in the settlement area Yucumo, General José Province Ballivián, Beni, Bolivia, taking into account the possibility that these cause public health problems not only in animals, but that they affect humans.
