Abstract

The surface fine structures of Ixodes persulcatus (Schulze, 1930) male and female specimens were observed by means of a scanning electron microscope. A brief review on the biology of the ticks and their disease relationships was also presented. The sexual dimorphism of the specimen was marked; the male was quite smaller than the female. The genital groove was well developed and deep, the anal groove was distinct and characteristically extending anteriorly around the anus. The 4th article was much reduced and situated on the top of the 3rd article ventrally. The hypostome dentition was usually 3/3. The bottom of the basis capitulum of the male specimen was strictly straight in shape. This species was regarded as one of the most important vectors for infectious diseases of migrating birds.
