Calculations based on adults identified to species. Prevalence calculated as the number of pigs infested divided by the number of pigs surveyed and expressed as a percentage. Abundance calculated as the sum of ticks collected divided by the number of pigs surveyed. Intensity calculated as the sum of ticks collected divided by the number of pigs infested. AMAU = A. auricularium, AMMA = A. maculatum, DEVA = D. variabilis, IXSC = I. scapularis.
