Fauna ixodológica do pavilhäo auricular de eqüinos em municípios de Minas Gerais e da Bahia / Ixodological populations of the ears of equines in Minas Gerais and Bahia, Brazil

RESUMO

Between June/1990 and February/1991, an experiment about ixodological populations of the ears of equines from counties of Minas Gerais and from Guanambi, Bahia, was carried out. Anocentor nitens was the mostprevalent (97.50 per cent) and most abundant (98.35 per cent) species, followed by Boophilus microplus (36.10 per cent and 1.59 per cent) and Amblyomma cajennense (20.50 per cent e 0.06 per cent). The larvae of A. nitens and B. microplus were more prevalent than the other parasitic stages, and we didn't find larvae of A. cajennense. The ratios between male and female were 3.5 and 1.7, to B. microplus and A. nitens, respectively (
