BACKGROUND
Ticks are hematophagous arthropod belonging to the Class of Arachnids. Ticks are also one of the major vectors of pathogens to animal and human. This study was conducted to determine tick infestation rate of sheep in Abdanan during 2007-2008.
METHODS
Sampling was performed seasonally in 19 villages during spring 2007 until winter 2008. A total of 1095 sheep were selected and tested for tick infestation. After collection, all ticks were transported to laboratory of Medical Entomology and were identified with appropriate identification keys.
RESULTS
Totally, 864 hard ticks were collected. The ticks were classified into two genera and 5 species including: Hyalomma marginatum (44.67%), Hy. anatolicum (43.17%), Hy.asiaticum (6.37%), Hy. dromedarii (5.55%), Heamaphysalis sulcata (0.24%). The highest seasonal activity was observed in spring (36.46 %) and the lowest seasonal was in winter (11.57%). The rate of tick frequency in mountainous region was 48.15% and it was 51.85% in plateau regions. In this study, tick infestation of sheep was 11.41%.
CONCLUSION
Hy.marginatum has the more frequent density in the study area.
背景
蜱是属于蛛形纲的吸血节肢动物。蜱也是动物和人类病原体的主要传播媒介之一。本研究旨在确定2007 - 2008年期间阿卜达南地区绵羊的蜱感染率。
方法
在2007年春季至2008年冬季期间，对19个村庄进行季节性采样。共选取1095只绵羊进行蜱感染检测。采集后，所有蜱被运至医学昆虫学实验室，并用适当的鉴定方法进行鉴定。
结果
共采集到864只硬蜱。这些蜱被分为2个属和5个种，包括：边缘璃眼蜱（44.67%）、安纳托利亚璃眼蜱（43.17%）、亚洲璃眼蜱（6.37%）、单峰驼璃眼蜱（5.55%）、苏氏血蜱（0.24%）。春季观察到最高的季节性活动（36.46%），冬季最低（11.57%）。山区的蜱感染率为48.15%，高原地区为51.85%。在本研究中，绵羊的蜱感染率为11.41%。
结论
在研究区域，边缘璃眼蜱的密度更为常见。
