摘要:

In newly hatched larvae ofBacillus rossius(Insecta Phasmatodea) viewed with light and electron microscopes, ovarioles appear as bag-like structures; during the first instar they initially assume a bell-shaped appearance. Afterwards, they begin to elongate and their vitellarium essentially consists of a row of oocytes with a clear growth gradient. This typical ovariole morphology becomes more evident in the subsequent instars up to the fourth.
