The distribution of overwintering arthropods in a sheep pasture in Utah County, Utah

Ashley, Richard Frank 01 May 1968 (has links)
The parasitic mites on mammals living in the chaparral community of Utah are practically unknown ecologically. Keegan (1953) was the first to publish on parasitic mites from Utah. He listed mites of 12 species and 9 genera from Tooele and Juab counties from hosts which included one Peromyscus truei, five P. crinitus, and 20 P. maniculatus. Brennan and Beck (1955) published on the chiggers of Utah and included a key to 38 species. Allred (1954, 1956, 1957, 1958) studied the geographical distribution, seasonal occurrence, and biology of mites found on mice of the genus Peromyscus in Utah.
