Background and Objective: Hard ticks (Acari: Ixodidae) are one of the most important obligate ectoparasites of vertebrates, belonging to class Arachnida, which transmit a wide range of pathological agents such as viruses, bacteria, and parasites to humans and animals in Iran and around the world. Identifying the distribution of hard ticks in a region is important to monitor their control program, and thereby prevent disease transmission.
Materials and Methods: In this cross-sectional descriptive study, sampling was carried out from different parts of the livestock body during four seasons in four geographical directions and five villages of Famenin County, Hamadan Province, Iran, during 2015-2016. The ticks were initially stimulated by using chloroform solution and then separated from domestic ruminants by forceps. The collected ticks were sent to a laboratory, and then their sex and species were identified by using valid diagnostic keys.
Results: We studied 800 domestic ruminants, including cattle, sheep, and goats, and found 150 (18.7%) cases of infestation. A total of 274 ticks were collected, 259 of which were hard ticks including four genera of Hyalomma, Dermacentor, Repicephlus, and Haemaphysalis. The greatest diversity
of species, including Hyalomma scopens (Hy. deteritum), Hyalomma asiaticum, Hyalomma marginatum, and Hyalomma anatolicum belonged to the genus Hyalomma. The frequency rates of Hyalomma, Dermacentor, Rhipicephalus, and Hemaphysalis genera were 73.74%, 15.05%, 10.03%, and 1.15 %, respectively. The highest abundance of ticks was observed in spring (152).
Conclusion: The results of this study indicate the diversity of hard ticks in the region and the highest abundance of ticks in spring. Considering the importance of ticks in disease transmission among humans and domestic ruminants, health authorities and respective organizations should take appropriate health measures to control and combat these external parasites
