پراکندگی و تنوع زیستی کنه های سخت (Acarina: Ixodidae) در استان گلستان
Authors
Abstract:
Background and Aims: Ticks are external parasites that can be vectors of several diseases agents. A survey was carried out to determine distribution and biological diversity of hard tick species in Maraveh Tapeh County, Golestan Province in spring 2016. Materials and methods: In 10 selected villages in study area, About 29 cattle, 99 sheep, 62 goats and 11 camels were inspected for tick infestation. Separated ticks were preserved in 70% alcohol and were identified. The Margalef, Shannon-wiener, Simpson and Evenness indicators were used to measure the biodiversity. Results: The overall 476 ticks were collected. Two genus (Hyalomma, Rhipicephalus) and twelve hard tick 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. R. sanguineus was the most abundant species in the study area. Hy. asiaticum was the most abundant tick in plateau areas, as well as R. sanguineus in the both hillside and mountainous areas. Based on Margalef indicator, Species richness was higher in foothill areas and in the goat's host was less than the other hosts. And Based on Shannon-wiener indicator, Species diversity was higher in plateau areas and in the sheep's host was less than the other hosts. Conclusion: population dynamic studies and calculating biodiversity indices are helpful in understanding the status of vectors and the landscape of the vector-borne disease.

مقدمه و هدف: کنه های سخت گروهی از بندپایان انگلی هستند که با خونخواری از مهره داران، در انتقال انواع عوامل عفونی (باکتری، ویروس وتک یاخته)، ایجاد مسمومیت و کاهش تولیدات دامی، نقش کلیدی دارند. این بندپایان در چرخه‌ی زندگی خود، نه تنها حیوانات اهلی، بلکه طیف گسترده‌ای از حیات وحش را نیز آلوده ساخته و همراه با این حیوانات، از منطقه‌ای به منطقه دیگر گسترش می یابند. جوجه تیغی برنت(Hemiechinus...

Background : Hard ticks ( Ixodidae family) transmit Arboviruses, bacteria and parasites to human and animals. One of the most important viruses that ticks transmit from animals to human is Crimean-Congo haemorhagic fever virus, the fact that its importance has been proved. So the study of fauna of ticks in the area, for the control and prevention of the mentioned disease, is of great importan...
