KEANEKARAGAMAN EKTOPARASIT PADA TIKUS RUMAH RATTUS TANEZUMI dan TIKUS POLINESIA RATTUS EXULANS DI DAERAH ENZOOTIK PES LERENG GUNUNG MERAPI, JAWA TENGAH

Study on poly-ectoparasitism and index diversity of ectoparasite species of roof rat Rattus tanezumi and Polynesian rat Rattus exulans of the slopes of Mount Merapi, Selo and Cepogo sub district, Boyolali district, Central Java was conducted from May-December 2000. The aim of this study was to accounter the poly-ectoparasitism and index diversity of ectoparasite species in Rattus tanezumi and Rattus exulans. Five main groups of ectoparasites were found on the bodies of roof rat and Polynesian rat were mites, chiggers, ticks, lice and fleas. In the bodies of roof rats R tanezumi were found 10 species of ectoparasites. They were 2 species of fleas, Xenopsylla cheopis and Stivalius cognatus, 2 species of lice Polyplax spinulosa and Hoplopleura pasifica, 5 species of chiggers Leptotrombidium deliensis, L. lacunosa,and Gahrliepia disparunguis, 2 species of mites Laelap echidninus and L. nuttalli and 1 species of tick Ixodes sp., whereas in the bodies of polynesian rat Rattus exulans were found all of species ectoparasites, exceptly chigger L. lacunosa and ticks Ixodes sp. Species of chiggers L. fletcheri and Celadonta were found too in the bodies of Rattus exulans. Poly-ectoparasitism and indexs diversity of ectoparasites species on the bodies Rattus tanezumi and Rattus exulans (male and female) in domestic and peridomestic habitat in slope of Merapi Mountain, Central Java were not different significantly.
