A total of 3655 samples collected from people applied to the hospitals with a complaint of tick bite between February 2007 and November 2008 in Aydin Province (Turkey) were examined in the present study. The samples were evaluated in respect to species, sex, development periods, host speciality and seasonal distribution. Of 3655 samples, 14,49 % (n=530) were not ticks. On the other hand, 12,33 % (n=462) of examined samples were comminuted and therefore could not be identified on the basis of genus or species. Results indicated that 9 out of 2664 ticks (0,3%) were Argasidae, while 2655 of them (99,7%) were Ixodidae. Evaluation of the developmental periods of ticks and the distribution of tick species indicated that the majority of the ticks were the nymph of Hyalomma spp. (n=1718), constituting 64,71% of all samples. Results obtained from the present study further indicated Hyalomma marginatum (n=409, 15,40%) as the most common tick species among adult ticks within the Hyalomma spp.
