Abstract

Cytological investigations combined with cytophotometric DNA determinations on Feulgen stained squash preparations of ovarioles from third and fourth instar nymphs of Carausius morosus revealed that during meiotic prophase a largely despiralized stage follows pachytene and that in this stage an extra reduplication of the nuclear DNA takes place (“pachyreduplication phase”). Meiotic prophase then proceeds with “tetrapachytene”, a pachytene-like stage with twice the amount of DNA as compared to oocyte nuclei in earlier meiotic stages, and with more than half the somatic number of elements, being probably autobivalents.
