XLI. Arthropod parasites of impalas (Aepyceros melampus) in the Kruger National Park0 aParasites of domestic and wild animals in South Africa XLI Arthr  c2003  a131 - 1630 v703 a<p>Ectoparasites were collected from impalas, Aepyceros melampus, at four localities within the Kruger National Park, namely Skukuza, in the Biyamiti region, Crocodile Bridge and Pafuri. Animals were also examined at Skukuza during a severe drought and at Skukuza and Pafuri towards the end of a second drought. Parasite burdens were analysed in relation to locality, sex, age class, month and drought. The impalas were infested with 13 ixodid ticks species, including two that were identified only to genus level. Except for four animals at Pafuri, all were infested with Amblyomma hebraeum. The highest intensity of infestation with larvae of this tick occurred from April to June and during November and December at Skukuza and in the Biyamiti region. Infestation with nymphs was highest during late winter. All animals were infested with Boophilus decoloratus, and the intensity of infestation was highest during spring. The intensity of infestation with Rhipicephalus appendiculatus was highest at Crocodile Bridge and at Pafuri, and that of Rhipicephalus zambeziensis at Skukuza. With both the latter species the intensity of infestation of larvae was highest from April to August, of nymphs from July to September or October and of adults during February and March. Rhipicephalus kochi was present only at Pafuri. The impalas also harboured five louse species and two species of hippoboscid flies. The intensity of infestation with lice tended to be greater during late winter and spring than during other seasons and greater on lambs than on yearlings on which it was greater than on adult animals.</p>

Similar collections were made from adult animals in extremis in the same landscape zone during October and November of the drought of 1982 as well as from 15 to 22-month-old male impalas examined at monthly intervals from March to October of the drought of 1992. The louse burdens of the adult animals examined during the 1982 drought were significantly greater than those of adult animals examined during the same months of 1980, a year of normal rainfall. The tick burdens were also larger, but not significantly so. The tick and louse burdens of the young impalas examined during the drought of 1992 were significantly smaller than those of animals of the same age examined during 1980.</p>
