Ektoparasiten (Zecken) an Testudo graeca ibera auf der Insel Kos, Griechenland

Ectoparasites (ticks) on Testudo graeca ibera on the island of Kos, Greece



Abstract

During a herpetological survey on the island of Kos, the authors observed Testudo graeca ibera. Data about quantity and position of any ticks found on the tortoises were collected. These ticks belonged to the species Hyalomma aegyptium and were mainly found around the hind limbs and tail. Sub-adult tortoises were significantly less infested by ticks than adults. A significant proportion of juvenile tortoises (measuring 3 to 13cm) had no ticks at all. Infection with ticks appeared to occur on tortoises which were were bigger than 13 cm. Similar observations and results were made by one of the authors during surveys on Testudo graeca ibera in Turkey. Possible reasons why only adult tortoises become infested by these parasites are discussed. A photo of Hyalomma aegyptium and its eggs is also presented.
