Occurrence of Ixodes pacificus (Parasitiformes: Ixodidae) in Arizona

J Med Entomol. 1992 Nov;29(6):1060-2. doi: 10.1093/jmedent/29.6.1060.


Adults and immatures of Ixodes pacificus Cooley & Kohls were collected by flagging vegetation and from lizards during a 3-mo period in the Hualapai Mountain Park, Mohave County, AZ, in 1991. Collections were made at altitudes > or = 2,134 m. Two of 48 gut-salivary gland extracts of adult ticks were positive by IFA using a monoclonal antibody (H5332) specific to Borrelia burgdorferi. These are the first records of I. pacificus and of spirochetes tentatively identified as B. burgdorferi in Arizona.
