Seventy-three nyalas (Tragelaphus angasii) in the Umfolozi, Mkuzi and Ndumu Game Reserves in northeastern KwaZulu-Natal were examined for arthropod parasites during 1983 and 1984. In addition, six animals were examined during 1994. Ten ixodid tick species, two louse species and a louse fly species were recovered. The nyalas were good hosts of all stages of development of Boophilus decoloratus, Rhipicephalus appendiculatus and Rhipicephalus muehlensi and the immature stages of Amblyomma hebraeum and Rhipicephalus maculatus. Adult male animals harboured more adult ticks, biting lice and louse flies than did adult females. B. decoloratus was generally most abundant from October to May. The larvae of R. appendiculatus peaked from April to October, nymphs from July to October and adults, on adult male nyalas, from February to May. Larvae of R. maculatus were most abundant from May to July and nymphs from June to October. The immature stages of A. hebraeum and all stages of R. muehlensi were present throughout the year.
1983年至1984年期间，对夸祖鲁-纳塔尔省东北部乌姆福洛齐、姆库齐和恩杜姆野生动物保护区的73只林羚（安氏林羚）进行了节肢动物寄生虫检查。此外，1994年还检查了6只动物。共发现10种硬蜱、2种虱和1种虱蝇。林羚是无色牛蜱、附加扇头蜱和穆氏扇头蜱各发育阶段以及希伯来花蜱和斑纹扇头蜱未成熟阶段的良好宿主。成年雄性动物身上的成年蜱、咬虱和虱蝇比成年雌性动物多。无色牛蜱通常在10月至次年5月最为常见。附加扇头蜱的幼虫在4月至10月达到高峰，若虫在7月至10月达到高峰，成年雄性林羚身上的成虫在2月至5月达到高峰。斑纹扇头蜱的幼虫在5月至7月最为常见，若虫在6月至10月最为常见。希伯来花蜱的未成熟阶段和穆氏扇头蜱的所有阶段全年都有。
