Regenerative modifications in the external structure of Haller's organ in nymphs of Ixodes ricinus L. (Acari: Ixodidae)
Acarina 7 (1), 29-33
Abstract: The structural modifications in regenerated Haller's sensory organ in nymphs of Ixodes (Ixodes) ricinus from which forelegs have been amputated at larval stage, are similar with those in nymphs of another prostriate tick, I. (Afrixodes) rubicundus. In both cases the nymphal regenerates re-establish larval features through a reduction of some sensilla in two compartments of the organ (on the distal knoll and in the post-capsular area). This juvenilization of Haller's organ is explained as a result of peculiarities in regenerative processes under hormonal condition during larval-nymphal metamorphosis (high juvenile hormone content).
