Domestic stock on a farm 30 km north of Grahamstown were treated with an acaricide at regular intervals over a period of several years. This resulted in a marked reduction in all stages of development of Amblyomma hebraeum on kudu (Tragelaphus strepsiceros), scrub hares (Lepus saxatilis) and helmeted guinea fowl (Numida meleagris) which were on the farm compared with the burdens of similar anim...
An artificial feeding unit with a reinforced silicone membrane to replace host skin provides ticks with a perch over blood with a tick attachment rate of 75-100%. Some 5 mg of an acaricide like fipronil is sufficient to establish survival curves over different doses down to ppb levels in blood. This in vitro feeding assay for hard ticks is more advantageous than in vivo trials on animals.
In order to evaluate milk producers' knowledge about tests on tick sensitivity to acaricides, efficiency tests and strategic control, questionnaires were delivered to 670 producers. From these, 163 responses were received. These producers had sent ingurgitated female ticks to be subjected to tests on tick sensitivity to acaricides at Embrapa between 2001 and 2005. Most of the completed question...
This study was designed to reveal out the prevalence of Sarcoptic mite infestation and the risk factors associated with occurrence of mange in one-humped camels (Camulus dromedarius) at smallholder farms in Upper Egypt, and to develop an applicable therapeutical protocol for the Sarcoptic mange infested camels. A total of 660 one-humped camels were randomly selected from different villages of A...
