九州本土域におけるマダニ相の調査

抄録

From April 1991 to July 1995,we surveyed by flagging the geological and vertical distributions of adult ticks, and also their seasonal occurrences in the Kyushu mainland, Japan. A total of 3,815 unfed adult ticks which were collected at 14 localities consisted of four genera and 13 species; Amblyomma testudinarium, Dermacentor taiwanensis, Haemaphysalis flava, H. longicornis, H. kitaokai, H. hystricis, H. megaspinosa, H. campanulata, H. formosensis, Ixodes ovatus, I. persulcatus, I. monospinosus and I. nipponensis. Tick fauna in the southern part of Kyushu was abundant in species and numbers; especially the genus Haemaphysalis tick was predominant while in the northern part it was relatively scarce. The genus Ixodes ticks including I. persulcatus, a typical northern species, were found around 800-1,300m above sea level in Kuju and Sobo Mountains. Mt. Kuju apparently is the southern limit for I. persulcatus distribution.
