Some Factors Influencing Incidence And Degree Of Ectoparasitism Of Small Mammals From Taiwan1

During January-February, 1962, small mammals of 2 orders and 9 genera were collected from 5 habitats at 2 different montane localities in Taiwan. Records of ectoparasites removed from these hosts were analyzed. Distribution of ticks was related to cover-type; incidence of infestation to host head and body length. Fleas were found most commonly at high, cold localities. Incidence of fleas, but not degree of infestation, was directly related to host body size. Lice were recovered from four genera, most common Apodemus and Rattus. Sex did not affect frequency or degree of infestation significantly. Degree of infestation was directly related to host body size.
