title: [Efficacy and residual effect of amitraz (Taktic) on adult Hyalomma dromedarii in camels: preliminary trial].
abstract: Amitraz (12.5% emulsifiable concentrate) was tested against Hyalomma dromedarii of the one-humped camel in a dairy camel herd in Nouakchott (Mauritania), at a concentration of 0.025% of the active component. The efficacy on adult ticks and the rapid rate of tick detachment are clearly shown: 95% reduction within eight hours; however, the nymphs seem to be more resistant: only 50% reduction after eight hours. The residual activity of amitraz against Hyalomma dromedarii in camels is very short, less than 24 hours; furthermore, the amitraz treatment has no effect on survival, oviposition and the rate of egg hatching of females which attach in the first days following treatment. A discussion of likely causes of this phenomenon is presented.
