Parasites of domestic and wild animals in South Africa. XL. Ticks on dogs belonging to people in rural communities and carnivore ticks on the vegetation

Abstract

Ixodid ticks were collected at weekly intervals from February 1999 to April 2000 from domestic dogs belonging to people in rural communities in north-eastern KwaZulu-Natal. Seven ticks were identified to species level and adult Haemaphysalis leachi followed by immature Amblyomma hebraeum and adult Rhipicephalus simus were the most prevalent. Infestation with adult H. leachi was most intense during February and March 1999 and from January to April 2000, and least intense during October 1999. Infestation with adult R. simus was most intense during February and March 1999 and least during July and September of the same year. For 12 consecutive years, from August 1988 to July 2000, free-living ticks were collected at monthly intervals from the vegetation of two landscape zones in the Kruger National Park. Most adult H. leachi were collected in the one zone from March to June, and no ticks were collected in October, whereas, with the exception of March, most were collected in the other zone during the period January to June, and only one tick was collected in October. Most adult R. simus were collected during February and March at both localities and only a single tick was collected in September. Adult Rhipicephalus turanicus was present only in the one zone and was collected only from January to June.
