通过荧光染色整个封片以及南瓜制备物来检查蟋蟀Gryllus bimaculatus的受精和早期胚胎有丝分裂。卵细胞减数分裂发生在卵细胞的腹面附近，而精子在背侧的细胞质岛中转化为精子原核。在减数分裂后，卵原核穿过卵向岛上的精子原核移动，在那里这些核发生结合。第一次卵裂有丝分裂是gonomeric的，如在Pyrrhocoris，Drosophila和Pyrrhox中。第三次卵裂后，核分裂的同步性丧失，沉积后12 h，分裂的核遍布整个卵。J. Morphol. 254：266-271，2002.© 2002 Wiley利斯公司
Fertilization and early embryonic mitoses of the cricket Gryllus bimaculatus were examined by fluorescence staining of whole‐mount as well as squash preparations. Egg meiosis occurs near the ventral surface of the egg, while sperm transforms into a sperm pronucleus in the cytoplasmic island on the dorsal side. After meiosis, the egg pronucleus moves across the egg toward the sperm pronucleus in the island, where union of these nuclei occurs. The first cleavage mitosis is gonomeric, as in insects such as Pyrrhocoris, Drosophila, and Bombyx. After the third cleavage the synchrony of nuclear division is lost and the dividing nuclei are distributed all over the egg by 12 h after deposition. J.
