Summary
In vitro spermatogenesis of isolated single spermatocyte cysts of Drosophila hydei was studied by microscopic observations and time-lapse cinematography. Cysts of spermatocytes isolated during diplotene develop as far as the coiling stage of spermatid differentiation. The existence of an interphase between meiosis I and meiosis II is, for the first time, documented. Meiosis, Nebenkern formation, and elongation of spermatids occur just as in D. melanogaster; however, an individualization cone, as described for D. melanogaster, can not be detected.
