  • Title: Pathways of regeneration of Haller's sensory organ during the life cycle of the tick Hyalomma asiaticum.
    Author: Belozerov VN, Leonovich SA.
    Journal: J Exp Zool; 1995 Feb 15; 271(3):196-204. PubMed ID: 7699360.
    Abstract:
    A study of regeneration in nymphs and adults of the Asiatic desert tick, Hyalomma asiaticum, from which forelegs had been amputated during the previous instar, revealed that regenerated Haller's sensory organs exhibited significant changes in structure. Adult regenerates possessed atavistic features in terms of the number and topography of different sensillar types. Regularity in these changes was similar to that demonstrated in regenerates of Ixodes ricinus (Leonovich and Belozerov [1992] Exp. Appl. Acarol., 15:59-79). Nymphal regenerates, by contrast, had larval features of the parent species. An hypothesis is presented about the ontogenesis of the complete, peripheral, polymodal sensory organ as a process in which the initial cell differentiation of cells begins at different starting points.
