title: Some helminth and arthropod parasites of the grey duiker, Sylvicapra grimmia.
abstract: Sixteen grey duikers were culled on the farm Riekert 's Laager in the central Transvaal at irregular intervals from May 1979-March 1981. One trematode species, 3 cestode species and 16 nematode species were recovered from these animals. Of these the following are new helminth records for this antelope: Cooperia hungi , Cooperia neitzi , Cooperia pectinata , Trichostrongylus axei, Trichostrongylus colubriformis, Trichostrongylus falculatus , Trichostrongylus instabilis , Impalaia tuberculata , Nematodirus sp. and Paramphistomum sp. In addition, 6 species of ixodid ticks were collected. These, in order of abundance, were Amblyomma hebraeum (55,9%), Rhipicephalus appendiculatus (36,6%), Rhipicephalus evertsi evertsi (5,1%), Boophilus decoloratus (2,3%), Boophilus microplus (0,05%) and Haemaphysalis sp. (0,05%). Only 60 (2,8%) of the 2 118 ticks that were collected were adults. Of the 3 species of lice that were recovered, Linognathus zumpti zumpti was most abundant (58,9%), but, out of a total of 1 498 collected, 1 496 occurred on 1 animal only. Linognathus breviceps constituted 29,5% and Damalinia lerouxi 11,6% of the total. A total of 277 specimens of the hippoboscid fly Lipoptena paradoxa were collected from 12 of the 16 animals examined. Trends in the seasonal fluctuation of Haemonchus, Trichostrongylus, Impalaia , Lipoptena and the immature stages of Amblyomma and R. appendiculatus are graphically illustrated.
