Trends in vector spread, however, suggest that patterns of tick distribution and abundance may have changed or will change rapidly in the near future ( Diuk-Wasser et al. ![]() As a result, there are relatively few reports of these vectors in the North Carolina Piedmont, leaving North Carolina with considerably fewer Lyme disease cases than states to the north, including nearby Virginia ( Lantos et al. scapularis than states to the north and south, especially in the Piedmont region between the mountains and coastal plain ( Eisen et al. North Carolina also has fewer reported counties with I. variabilis were present in the central and western areas of North Carolina ( Diuk-Wasser et al. americanum to the East and Southeast ( Diuk-Wasser et al. Interestingly, the Piedmont of North Carolina, a region of high human population density, is situated in an apparent gap in the distribution of I. Dermacentor variabilis Say, the American dog tick, is widespread in both northeastern and southeastern states and has a distribution that overlaps that of I. ![]() The predominant tick species of the Southeast is A. scapularis are typically higher in the Northeast ( Bishopp and Trembley 1945, Eisen et al. Ixodes scapularis, the vector of Lyme disease, is present in both the Northeast and Southeast United States, but densities of I. are the most abundant tick species encountered by humans ( Trout Fryxell and Vogt 2019). In the eastern United States, Ixodes scapularis Say and Amblyomma americanum L. Two of the most important determinants of human tick-borne disease (TBD) risk are tick occurrence and abundance ticks must occur in a region for them to act as pathogen vectors and the probability of pathogen transmission increases, in part, as a function of tick abundance. North Carolina, tick abundance, tick survey Our results indicate the possibility of underlying habitat and host factors limiting tick distribution and abundance in the North Carolina Piedmont. From these surveys, we had only 20 tick captures, illuminating the surprisingly low abundance of ticks in this region of North Carolina. We surveyed for ticks using cloth drags, CO 2 traps, and leaf litter samples at a total of 79 sites within five locations: Mecklenburg County, South Mountains State Park, Stone Mountain State Park, Duke Forest, and Morrow Mountain State Park, all in North Carolina, during the late spring, summer, and fall seasons of 2019. Here, we update the known occurrence and abundance of these species in the North Carolina Piedmont. Despite this, there are few records of these species in the Piedmont of North Carolina, including the greater Charlotte metropolitan area. North Carolina is at the nexus of spread of these species, with high occurrence and abundance of I. Multiple species of ticks, including Ixodes scapularis (Say, Ixodida:Ixodidae), Amblyomma americanum (L., Ixodida:Ixodidae), and Dermacentor variabilis (Say, Ixodida:Ixodidae), occur in high and increasing abundance in both the northeast and southeast United States. ![]()
