Leonovich, V. Belozerov] Amputation of legs in nymphs of ticks, obtained from the first laboratory generation, resulted in regeneration of the legs after moulting to adults. Haller's sensory organ on the upper surface of each foreleg tarsus was significantly modified following regeneration. Haller's organ in non-amputated legs of the experimental ticks remained unchanged, being comparable to controls. Pored olfactory sensilla in the anterior pit, in a capsule and on a distal knoll usually increased in number, as well as grooved, thin and conical sensilla. Bordering gustatory and double-walled postcapsular sensilla either decreased or increased in number. All additional sensilla were consistent in their location. Form of the anterior pit and capsule's aperture also deeply changed after the regeneration. The authors distinguish this changes as atavistic. No correlation between changes in different parts of the organ were found. A phenomenon of induction was discovered in our study: if a distal part of tick's gnathosoma was amputated together with the left foreleg, Haller's organ in the right, untreated leg possessed the same changes after moulting as the regenerated organ in the previously amputated left foreleg.
