The epithelium of the mid-gut of Blattella germanica L. classified cockroaches was observed with light microscope.
1. The mid-gut structure was composed of peritrophic membrane, epithelium cell, basement membrane and muscles.
2. The epithelium of mid-gut was composed of columnar, goblet and regenerative cells.
3. A regenerative cell was taken the place of epithelium cellsecration enzyme by destrctive metabolism.
4. Mid-gut structure does not change during the metamorphosis.
