This study reports the effects of <em>Consolida orientalis</em> (Ranunculaceae) extract on the larval stage of <em>Argas persicus</em> (Acari: Argasidae). In order to determine the efficacy of the extract on the larval stages and mortality of ticks, the dipping method was used. To determine the lethal concentration, three suspensions 1%, 10% and 100% from this extract and distilled water as a control group were used. This extract showed pesticide effects in comparison with the control group on the larval stage of tick (p < 0.05%). It showed 100% mortality with minimum concentration for larvae. According to the results and the abundance of this plant, it is suggested that more work must be done on the effect of the <em>C.</em> <em>orientalis</em> extract on the different life stages of hard and soft ticks.  https://www.persianacarology.org/article_239345_f152d2465d4f817721501dc776c5dabc.pdf
