Knockdown and persistence efficacies of a pour-on containing Amitraz 1% and Cypermethrin 1% and a spray dip containing 12.5% Amitraz were compared. Knock-down and persistence efficacies of the Amitraz spray dip against Rhipicephalus (Boophilus) decoloratus and Amblyomma hebraeum were significantly higher for the duration of the trial than those of the pour-on. In the case of Rhipicephalus apped...

A study was conducted to compare the species of adult ixodid ticks on Friesian and Bonsmara cattle and their seasonal dynamics. Between five and ten animals of each breed were kept on natural False Upper Karoo vegetation, typical of the south-western Free State. Between May 1990 and October 1991, the animals were examined once or twice a month for the presence of adult ticks which were removed,...

The study aimed to assess the long-term population dynamics of questing Rhipicephalus appendiculatus and Rhipicephalus zambeziensis in two landscape zones of the Kruger National Park (KNP). Ticks were collected by dragging the vegetation monthly in three habitats (grassland, woodland and gully) at two sites in the KNP (Nhlowa Road and Skukuza) from August 1988 to March 2002. Larvae were the mos...

BACKGROUND Ticks are important vectors of human and animal pathogens. They are considered as main vectors for transmission of many viral, bacterial, rickettsial and parasitical pathogens. The aim of the present study was to find out species diversity of ticks, which infested the domestic ruminants in Zabol County, Eastern Iran in 2012. METHODS Ticks were selected randomly from sheep, goats, c...

In order to determine the extent of acaricide resistance in the eastern region of the Eastern Cape Province 1-, 2- and 3-host ticks were collected from cattle at 59 dip-tanks over a period of 2 years. These ticks were tested for resistance against 3 compounds, namely amitraz, cypermethrin and chlorfenvinphos. The Shaw Larval Immersion Test detected emerging resistance to amitraz in Rhipicephalu...

Ticks carry and transmit a remarkable array of pathogens including bacteria, protozoa and viruses, which may be of veterinary and/or of medical significance. With little to no information regarding the presence of tick-borne zoonotic pathogens or their known vectors in southern Africa, the aim of our study was to screen for Anaplasma phagocytophilum, Borrelia burgdorferi, Coxiella burnetii, Ric...
