During years 1971 to 1973,the following species of ticks, consisting of about 13,000 specimens, were recorded from the southern Amami-oshima Islands, mainly around Mt. Yuwan-dake : Amblyomma geoemydae, A. nitidum, A. testudinarium, Boophilus microplus, Dermacentor taiwanensis, Haemaphysalis campanulata, H. flava, H. formosensis, H. hystricis, H. megaspinosa, H. pentalagi, Ixodes granulatus, I. asanumai, and Ornithodoros sawaii. The prevalences of the predominant four species, A. testudinarium, H. formosensis, H. hystricis and D. taiwanensis, might primarily depend on the existence of the wild boar, Sus riukiuanus.
