Abstract:
:Amblyomma rotundatum is an ixodid tick strictly associated with cold-blooded animals, among them the toad Rhinella jimi. This work aimed to evaluate the seasonal dynamics of larvae, nymphs, and adults of A. rotundatum parasitizing R. jimi in an area within the semi-arid Caatinga Biome of northeastern Brazil. Monthly sampling from February 2014 to January 2016 resulted in a total of 592 R. jimi toads captured and inspected for infestation by ticks, which were counted and identified. After the procedure, the toads were released with their ticks at the same capture site. During the study period, a total of 658 A. rotundatum were counted, comprising 497 larvae, 110 nymphs, and 51 females. The two-year mean abundances of larvae, nymphs, and adults were 0.84, 0.19, and 0.09, respectively. The two-year mean infestation intensities of larvae, nymphs, and adults were 3.65, 1.45, and 1.34, respectively. Comparing the monthly values of prevalence, mean abundance, and mean infestation intensity of A. rotundatum life stages, differences were observed between the first and second year of study; however, with no clear seasonal pattern.
