Tick infestations (Acari: Ixodidae) on three lizard species from Seraidi (Annaba District), northeastern Algeria.

Parasitism of Ixodes ricinus on three species of lizards (Psammodromus algirus, Podarcis vaucheri and Timon pater) in northeastern Algeria was studied. Psammodromus algirus was the most preferred host, T. pater was least preferred. Nymphs of I. ricinus were found attached to lizards from March to August in various numbers. Most nymphs were collected during March, April and June for P. algirus, and most larvae from April until August. Larval stages were found to be mostly associated with P. vaucheri during the study period, with the highest number of recovered larvae in June.
