Abstract
|
|
|
Ultrastructural changes of the testis in Pieris rapae L. observed under the electron microscope during the metamorphosis from prepupa to pupa. The peritoneal sheath, epithelium of the follicle and cucticle have the maximum thickness at prepupa stage and afterthen gradually they began to degenerate. The epithelium of the follicle which formed by invagination of the peritoneal sheath is differently differentiationed from the peritoneal sheath and it is similar to the adult¡¯s from the pupa 2 days. The cell organelles begin to increase in the cytoplasm of the cyst cell enclosed the sperm bundles at pupa 3 hrs. The electron densed granules which observed in the peritoneal sheath and epithelium of the follicle at prepupa seem to be related with fusion of the testis.
