Abstract : While studying the effect of repellents on different ecological types of ixodid ticks it was demonstrated that repellents are characteristically perceived by contact chemoreceptors in I. persulcatus and by olfactory chemoreceptors in Hyalomma asiaticum. Dissimilarities in the perception of repellents in these tick species is explained by their mode of living and manner of attacking prey. I. ricinus and I. persulcatus ticks have a better developed contact chemoreception than H. asiaticum, therefore it is advisable to apply repellents of low volatility for impregnation of cloth. Since distance chemoreception in H. asiaticum is particularly well developed, in comparison to ticks with a similar type of chemoreception, it is advantageous to apply repellents with high volatility. The reason for a well developed distance chemoreception in H. asiaticum may be its desert mode of living, and particularly the active manner of attacking the prey. The 'waylaying' type of questing for hosts of I. persulcatus in the forest chiefly depends on development of contact chemoreception.
