Long-horned tick distribution potential in North America

Ilia Rochlin, an associated researcher at the Center for Vector Biology, recently published an article exploring the potential distribution of the Asian longhorned tick, Haemaphysalis longicornis in a paper titled: Modeling the Asian Longhorned Tick (Acari: Ixodidae) Suitable Habitat in North America in the Journal of Medical Entomology. He uses maximum entropy distributions to model potential North American distributions based on old world distributions and climatic and ecological variables. Annual temperature, precipitation, and ecological zones were significant factors in determining that the eastern half (with a small slice of the Pacific Northwest) of NA appears to have suitable habitat for this tick. This tick could be of concerned for domesticated animals as well as the potential for spread of tiboviruses (tick-borne viruses) such as Heartland virus.
