[Visual potentialities of the tick Hyalomma asiaticum asiaticum (Ixodidae)].
Ethological experiments with the desert tick Hyalomma asiaticum asiaticum are conducted. It is shown that tick inhabiting open landscapes discovers his host using his eyes. Since the eyes of this species have a poor resolving possibility, black objects with white strips drawn on it are less attractive for the tick. When the tick scans an area looking for host, the principal optical axis of his eyes is directed not higher than 20 degrees. In allows the tick to discover objects having angular sizes of 5 degrees and greater.
