During 24 months 96 marsupials and 64 rodents were captured, inspected and set free in the same space of the Pedra Branca State Park, Rio de Janeiro. From them, 105 ticks from 10 species in two families were manually collected. The dominant tick species on the rodents was Amblyomma longirostre and on the marsupials was Ixodes loricatus. There was a significant correlation of the temperature in relation to intensity of parasitism for ticks, demonstrating that the higher the temperature, greater is the number of ticks.
