Abstract
Kakuda, H., T. Hirooka, T. Mori and S. Shiraishi, 1997. Ultrastructure of the lobular accessory glands in Haemaphysalis longicornis(Acari:Ixodidae). J. Acarol. Soc. Jpn., 6(1): 17-24.
The lobular accessory glands in female Haemaphysalis longicornis are derived from the epithelial lining of the vestibular vagina. As feeding proceeds, the epithelium increases in volume and becomes glandular. The apical region of the developing epithelium detaches from the vestibular cuticle, and the vestibular sinus is formed. Secretions from the epithelial cells are discharged into the sinal lumen and released into the genital tract through the vestibular cuticle.Well-developed microvilli, intercellular spaces and infoldings of the basal plasma membrane associated with mitochondria found in ovipositing females indicate transporting epithelia. The fact that secretory activity of the glands occurs during oviposition suggests that secretions from the lobular accessory glands are involved in the passing of eggs through the genital tract.
