The ixodid tick species are the most abundant tick parasites infesting ruminants in Iran. The current study reports ixodid ticks diversity and their seasonal distribution in the natural habitat of domestic ruminants in north and south of Iran from March 2007 to February 2008. A total number of 3900 cattle. 5444 sheep and 2825 goats in our stages (seasons) were randomly selected front both regions. Of those animals. 38.1% in the north and 21.1% in the south were infested with a total of 3409 and 2297 ticks. respectively. The prevalence of tick in differed significantly between two regions. The highest number of the ticks was collected from sheep in the regions. There was no significant difference between an gender and tick's infestation rate. A number of six genera and 12 species of ticks were identified in both regions. In north. Boophilus annulatus (56.16 %. 410/730), Ixodes resinus (31.15%, 148/475) and Hyalomma ascaticuni asciaticum (50%. 67/134) had the highest prevalence in cattle. sheep and goats. respectively. While in the south. predominant infesting tick was Hyalomma anatulicum anaatulicum with the infestation rate of 48.61% (88/181) in cattle. 46.47% (145/312) in sheep and 77.16% (152/197) in goats. Seasonal distribution of the ticks showed different patterns in two regions. Prevalence was correlated with temperature and humidity in both regions. The results revealed that the distribution of ixodid ticks species and their prevalence differed between two regions. mostly depending on the macro and microclimate conditions.
