ACE Pest Control Practice Test

Lyme disease is transmitted by Ixodes scapularis in many parts of the United States. This tick, also known as the blacklegged or deer tick, transmits Borrelia burgdorferi after feeding for a day or two, typically needing about 24–48 hours of attachment for transmission to occur. The other ticks listed are associated with different diseases (for example, Dermacentor variabilis with Rocky Mountain spotted fever, Amblyomma americanum with ehrlichiosis, and Rhipicephalus sanguineus with other pathogens), not Lyme disease. In the West, Ixodes pacificus serves a similar vector role, but Ixodes scapularis is the classic Lyme vector for the eastern and central U.S.
