The neurosecretory cells of pars intercerebralis, the corpus cardiacum and the corpus allatum are examined in histological sections of Lyperosia exigua females, fixed at daily interval during first cycle of egg maturation. The median neurosecretory A cells exhibit secretory activity by undergoing cyclical changes of synthesis and release with the advancing age and egg maturation. Similarly, a single corpus allatum also undergoes cyclical changes in volume and histological appearance in accordance with the yolk deposition in the developing oocyte.
