|Ticks are known as the most important vectors of the human and animal diseases. The soft fowl tick (Argas persicus) belongs to Argasidae family. Spinosad is a novel macrolide-class insecticide produced by the soil bacterium Saccharopolyspora spinosa and is known to be active against many noxious pests. Spinosad is one of the most important natural insecticides, which plays an essential role in controlling and eliminating pests. In contrast with other insecticides, the Spinosad is a low-risk insecticide for mammals without any carcinogenic, mutagenic, and tuberculous effects. Moreover, Spinosad does not result in cross-resistance due to the insect resistant to other insecticides. This investigation was carried out to evaluate effects of different concentration (0.5, 1, 5 and 10 mg/ml) of the acaricide Spinosad in three replications on the soft tick (A. persicus) under laboratory condition during 24 hours of exposure to Spinosad. Soft fowl ticks (A. persicus) were sampled, and five adult soft ticks were used for each treatment. In control group, ticks were dipped in distillate water. The adult tick mortality for the four doses of 0.5, 1, 5 and 10 mg/ml Spinosad was recorded as 13.33%, 40%, 66.66%, and 100%, respectively. The results indicated that Spinosad played a significant role as acaricide, and the effect was dependent on concentration. It was concluded that Spinosad would be a useful addition in a tick control program against Argas species.|
