Abstract:
The ovary of Haemaphysalis bispinosa was of panoistic type with asynchronous
development of oocytes. The wall of the ovary was composed of a layer of epithelial cells to
which the oocytes were attached by means of pedicel cells with elongated nucleus. The
oocytes were classified into stages I to V based on morphologic characteristics like size and
shape, presence / absence of germ vesicle, cytoplasmic appearance, presence or absence of
yolk granules and presence of chorion. Day wise changes were in the form of occurrence of
oogonia from partially fed upto day zero of engorgement, presence of all stages of oocytes on
day one and two after engorgement and onset of degenerative changes in oocytes from day
three onwards. Degeneration was complete on day eight with the appearance of polymorphism,
vacuolation, cytoplasmic blebbing and autophagic activity in oocytes.
