BACKGROUND: Today ticks usually develop resistance to pesticides, it is therefore necessary to search for alternatives to those currently available. In the meantime the active principles of plants with acaricidal properties are a promising alternative for the control of ticks and other arthropods. OBJECTIVES: The main aim of this work was evaluation of the effect of Matricaria Chamommila extract on larval and adult stages and mortality rate of Argas persicus and determination of the tick sensitivity to this plant extract. METHODS: In this study immersion method was used in order to determine of efficacy of extract on larval stage and mortality of ticks. To determine the lethal concentration, 3 suspensions 8%,2%,0.5% and 60% ethanol as control group was used from this extract. Tick immobility after turning them on their back was used as a viable or non-viable criterion. RESULTS: This extract showed considerable pesticide effects in comparison with control group (p<0.05%). Mentioned extract showed 60% mortality in 0.5 % concentration and 100% mortality in other used concentrations while the effect of extract was 0% in adult ticks. CONCLUSIONS: Our result showed that extract of Chamomile has considerable pesticide effect on larval stage of Argas, while against adult tick has no effect.
