Acrida anatolica and Parapholidoptera
spinulosa are two different species of migratory caterpiller in the same
family and both are threats to agriculture. They areharmful, they migrate and
spread wide areas. Herbivorous Acrida
anatolicahas strong chewy mouth part, mandibula is considered to be the
basic insect mouth type. Parapholidoptera
spinulosa a carnivorous species, has a strong chewing gut. The purpose of
this study is to compare the structures of the digestive tracts of these species.
The digestive tract is divided into three parts, the foregut, midgut, and the
hindgut. The prismatic epithelium, external circular and longitudinal muscles,
connective tissue, granular structures and peritrophic membrane are the parts
of the foregut. The caeceum is also found in this portion.The grasshoppers were
collected from the Ondokuz Mayis University Campus and kept in special containers
and fed with wheat grass, fresh grass and with different insects. During the
dissection process, the digestive tracts were removed and tissues were fixed
with 10% buffered neutral formalin solution for 24 hours. After routine
histological procedures, the sections were stained withhematoxylin-eosin (H-E).
Foregut, midgut and hindgut were comparatively examined in terms of peritrophic
membrane, epithelial tissue, cell size, nucleus size, circular and longitudinal
muscles, connective tissue, regenerative cells and cellular diversity.

            The knowledge of grasshopper histology and embryology
will contribute to the development of more efficient fighting with grasshoppers
and the development of agricultural plant protection products.
