| Summary: | The present study entails the description of the anatomy and histology of the alimentary canal
of praying mantis, Hierodula coarctata Saussure (Mantodea: Mantidae), a predatory insect.
The alimentary canal was isolated, processed and analysed anatomically and histologically by
using stereomicroscope and light microscope. The alimentary canal of H. coarctata is
classically divisible into foregut, midgut, and hindgut. The foregut has the pharynx,
oesophagus, crop and proventriculus which has histological layers intima, epithelium,
basement membrane and outer muscularia. The midgut is short with eight gastric caeca
anteriorly has a single layer of columnar epithelial cells show merocrine secretion and nidi
cell groups at regular intervals lined by lamellate peritrophic membrane internally and
muscular coat externally. The hindgut consists of the ileum, colon, and rectum with
histological layers viz. intima, epithelium, and muscles. The results of the present
investigation revealed that the alimentary tract of the carnivorous insect H. coarctata was
structurally and functionally adapted to digest and absorb protein-rich diet. |
