Abstract

A SURVEY of literature shows that Ioffe1 was the first to investigate in detail the distribution of neurosecretory cells in the ganglionic mass of hard ticks. He observed eighteen groups of cells distributed in different parts of the ganglionic mass of Dermacentor pictus Herm. and compared them with those in Ixodes ricinus (Linnaeus) and Hyalomma asiaticum Schulze and Schlottke. During the present investigation similar results were obtained in the ganglionic mass of Hyalomma dromedarii Koch (Acarina: Ixodidae) sectioned after staining with paraldehyde–fuchsin2, using a modified technique3.
