MITES (EXCLUDING CHIGGERS) OF MAMMALS OF OREGON'

.\bstr.\ct.- New information on the ectoparasitic mites of the following species of mammals from Oregon is pre-

sented: (1) pika—Ochotomi; (2) squirrels—Ewfamias, Spennophilus, Tamiascitirus; (3) grasshopper mouse— Oni/c/j-

omiis; (4) woodrats—Neoforjifl; (5) —Ondafra; (6) jumping mice— Z«pi/s,- and (7) weasels—Miisfe/a, Spilogale. New records of species for the state and new host records are also given. Finally, a cross-referenced list of all known mites of wild mammals from Oregon is presented.

Over the past several years, we have writ- and stained in Nesbitt's solution containing ten a series of papers on the ectoparasites of acid fuchsin, and mounted in Hoyer's solu- mammals from Oregon that include data on tion. Cover slips were ringed with Euperal. the mites of mammals from the following Identifications were verified by specialists as genera: Zapus (Whitaker 1979), Arborhrius necessary. and Lagurus (Whitaker and Maser 1979), Mites that constitute new records from Aplodontia (Whitaker et al. 1979), Neuro- mammals from Oregon are listed below. trichus and Scapanus (Whitaker et al. 1979a), Numbers in parentheses are the number of Sorex (Whitaker et al. 1980), Dipodomys and hosts with mites and the number of mites Perognathus (Maser and Whitaker 1980), found.

Part II: Mites (Excluding Chiggers) of Mammals from Oregon

The following list summarizes information on ectoparasitic and phoretic mites currently known from wild mammals of Oregon. Data are presented alphabetically by family, genus, and species. Host taxa identified only to genus are not included. Numbers after the species refer to papers, listed by number, in the literature cited. Those marked with an X are reported for the first time in this paper.
