The results of the determinating the activity of the CA in vitro showed that the CA of the water—fed individuals were in activing statics after eclosion. Because of the apperence of the Vg in haemolymph and the deposition of the vitellin in oocytes in the unfed females, it was shown that the CA in such individuals were in activiting statics, too. Again because in the water—fed females which did not lack the feeding action the activity of the CA showed dropping tendency gradually still, it could be said that the activiting of the CA was possibly effected by the nutrition but it was never related to the adult feeding action. In another respect, the brain of the female adult had not significant effect on the activiting CA. The oocytes could depositing vitellin in individuals removed brain tissue on the day of eclosion, which showed that the activting of CA was not concerned with brain.

Both the proteins components contained in haemolymph, fat body and ovary and the kenetics of the vitellogenin in haemolymph and ovary were analyzed by SDS—polyacrylamid electrophoresis, Ouchterlony plate tests and Rocket—immuno—electrophoresis. The results showed that the vitellogenesis initiated in adult stage and the Vg in haemolymph was detected firstly at 48h after eclosion. The titer of Vg in haemolymph raised rapidly in following 3 days and almost at the same time the vitellin appeared in oocytes. It was taken about 4—7 days after eclosion for the first eggs to grow up to the matured statics and to be laid out.
