Effects of Rickettsia amblyommatis Infection on the Vector Competence of Amblyomma americanum Ticks for Rickettsia rickettsii.

Vector Borne and Zoonotic Diseases, 2018
Although Dermacentor spp. ticks are considered the primary vectors of Rickettsia rickettsii in the United States, other North American tick species are also capable of transmitting the agent, including the lone star tick-Amblyomma americanum.

Multiple Introductions of the Asian Longhorned Tick (Haemaphysalis longicornis) to the United States Revealed Using Mitogenomics

Ecology and Evolution, Volume 15, Issue 4, April 2025.
The Asian longhorned tick, Haemaphysalis longicornis, is a significant global vector and threat to both agriculture and public health. Formerly known only in the Eastern Hemisphere, parthenogenetic ALT have been reported from 20 states across the eastern and central US, with a pattern of expansion suggestive of multiple distinct populations.
