Description

The surface structure of silkworm egg has been investigated by means of scanning electron microscope and differential interferencecontrast microscope. The matured eggs used in these experiments were taken out of oviduct in the adult moth of two silkworm strains, N124 and C124. With the evidences in the experiment, it was expected to describe the further fine structure of micropylar apparatus and the characteristics between strains.<br>The radiating gathers adhering were observed on the surface of central area in the petallike pattern of which micropylar apparatus was composed. Such gathers were not found in the outer area and the area was protruded as a knob which may envelop the other part of egg shell. This subtilized surface structure of the central area could indicate that the central area is not covered with outer layer of egg shell.<br>Small cavities found in the center of micropylar apparatus in N124 were polygone with 3-4 vertical angles, while the cavities in C124 were stellated struacute with 3-6 vertical angles. The significant difference in structure of small cavities between strains may be considered as a strain specificity.
