Evaluation of Susceptibility of Argas persicus (Acari: Argasidae) to Different Doses of Acaricides under Laboratory Condition

Ticks are known as the most important vectors of the human and animal diseases. The soft fowl tick (Argas persicus) belongs to Argasidae family. This investigation was carried out to evaluate effects of four doses of three acaricides: cypermethrin, phoxim and lambda-cyhalothrin in three replications on the soft tick under laboratory conditon. In control group, ticks were dipped in distillate water. Five adult soft ticks were used for each treatment and similar treatments were also evaluated for tick larvae. The adult tick mortality for the four doses of 10, 5, 0.5 and 0.125 mg/ml cypermethrin was recorded as 100%, 80%, 46.66%, and zero, respectively. The mortality rate of the four doses of phoxim and lambda. Cyhalolothrin was recorded as 100%, 33.33%, 26.66%, 20% and 100%, 66.66%, 33.33%, 26.66%, respectively. A. persicus was controlled by all three acaricides, but cypermethrin was found to be more effective than the others.
