Abstract
This survey was done to investigate the geographical distribution of ticks (Hard and Soft) in the towns of Amol, Babol and Noor in Mazandaran province, north of Iran. The study, conducted from January 2000 to October 2001, covered mostly rural districts and a total of 15 operational fields.
Ticks were collected from domestic fowl nests, stables (animal shelters, floors and other places), animal bodies and rodent holes. A total number of 3897 ticks from two families (Argasidae and Ixodidae) were collected. Ticks from the Argasidae Family totaled 2049 and belonged to 2 genera: Argas and Ornithodorus). The proportions of different species were as follows: Argas persicus 35.95%, A. reflexus 0.97% and O.lahorensis 15.65%. Hard ticks collected in the area belonged to 6 genera and included 8 species: Boophilus (B. annulatus 8.34%) Haemaphysalis (Hae. Sulcata 5%), Hyaloma (Hy. marginatum 1.66%), Dermacentor genus and Hyschulza (0.75%).
Hy. anatolicum (1.33%) De. marginatus (1.72%), the genus Rhipicephalus (Rh. Sanginues 1.18%) were collected from animal bodies (cow, sheep, goat) and animal shelters.

Abstract
Background and Aims: Ticks are external parasites that can be vectors of several disease agents. This survey was carried out to determine distribution and biological diversity of hard tick species in Maraveh Tapeh County, Golestan Province, Iran in spring 2016.
Materials and methods: In 10 selected villages in the study area, about 29 cattle, 99 sheep, 62 goats and 11 camels were inspected for tick infestation. The ticks isolated were preserved in a solution of 70% alcohol and identified. The Margalef, Shannon-Wiener, Simpson and Evenness indices were used to measure the biodiversity.
Results: A total of 476 ticks were collected. Two hard tick genera (Hyalomma and Rhipicephalus) and twelve species were identified including Hyalomma anatolicum, Hy. scupense, Hy. aegyptium, Hy. marginatum, Hy. dromedarii, Hy. rufipes, Hy. asiaticum, Hy. excavatum, Hy. detritum, Rhipicephalus turanicus, R. bursa and R. sanguineus. Further analysis of the data showed that R. sanguineus and Hy. asiaticum were the most abundant species in the whole area and plateau areas, respectively, while R. sanguineus was most abundant in both hillside and mountainous areas. Based on the Margalef index, the species diversity was higher in foothill areas and it was lower in the goat host than other hosts, while based on the Shannon-Wiener index, the species diversity was higher in plateau areas and in the sheep host it was less than in other hosts.
Conclusion: Ticks population dynamic studies and calculating their biodiversity indices are helpful in understanding the situation of vectors and the future situation of vector-borne diseases.

Abstract
Background and Aim: Ixodidae (hard ticks) are obligate blood-feeders of vertebrates with majorroles in transmission of pathogenic microorganisms including theileriosis, babesiosis and CCHF virus, as well as relapsing fever, to domestic animals and humans. This study was conducted to determine the distribution of ixodidae species, vectors of Crimean-Congo hemorrhagic fever (CCHF), in the border areas in North West of Iran.
Materials and Methods: This was a descriptive cross-sectional study conducted in Ahar and Kaliybar Counties, East Azarbaijan Province, Iran. Randomized cluster sampling was done in villages in the forest and mountainous regions. Ticks were isolated by forceps from the animals, kept in sampling tubes and transferred to the laboratory. Then the tick samples were identified using taxonomical keys.
Results: A total of 2022 hard ticks were isolated from 1400 head of livestock (1000, 200, 180 and 20 head of sheep, goat, cow and buffalo, respectively). On the average, the infestation rate was 1.44 per head of cattle ─ 0.11% in goats, 0.32% in sheep, 0.90% in buffaloes, 9.25% cows. Out of the ticks isolated, 498 (24.63%) were male, 741 (36.65%) were female and 782 (38.67%) nymph, plus one larva. The ticks belonged to the lxodidae family, including four genera: Hyalomma (88.82%, with the following three species: Hyalommaanatolicum (39.22%), Hyalommamarginatum (9.15%) and Hyalommaasiaticum (0.69%)); Rhipicephalus (8.8%); Dermasentor (1.58%); and Haemaphisalis (0.8%). The others identified were Hyalomma nymph (38.67%), Hyalomma sp. (1.04%) and Hyalomma larva (0.05%), Rhipicephalus bursa (5.19%), Rhipicephalussanguineus (3.61%), Dermasentor marinates(1.58%), Haemaphisalissulcata (0.59%), and Haemaphisalispunctata (0.15%), as well as Haemaphisalisconcinae (0.05%). Hyalommaanatolicum was the dominant species.
Conclusion: The dominant tick species in the regions studied was Hyalommaanatolicum, a tick having a major role in transmission of many disease vectors including CCHF, ovin babesiosis, theileriosis, anaplasmosis, ehrlichiosis, etc. It is essential that the provincial Contagious Disease Center and Veterinary Department take appropriate action with the collaboration of other relevant departments to combat the tick.
