Parasites of domestic and wild animals in South Africa. XVIII. The crowned guinea fowl (Numida meleagris), an important host of immature ixodid ticks.

The tick burdens of 10 crowned guinea fowl (Numida meleagris), shot at approximately 3-monthly intervals in the Mountain Zebra National Park, and of 21 crowned guinea fowl from the Andries Vosloo Kudu Reserve, the majority of which were shot at monthly intervals, were determined. No adult ticks were recovered from any of the guinea fowl. The birds in the Mountain Zebra National Park harboured 4 species of ixodid ticks of which Amblyomma marmoreum was the most abundant and most prevalent. Three birds also harboured Hyalomma marginatum turanicum. Six ixodid tick species were present on guinea fowl in the Andries Vosloo Kudu Reserve. Of these Amblyomma hebraeum was the most abundant and all the birds were infested. Most of these birds were also infested with A. marmoreum and Haemaphysalis silacea and some harboured Hyalomma marginatum rufipes. The seasonal abundance of ticks on crowned guinea fowl is discussed.
