Abstract : Grasshopper (Hieroglyphus banian), an orthopteran species is considered to be a serious pest of rice plant in India. The biology an life cycle of this pest is largely governed by the type of neuroendocrine system as well as the neurosecretory cells responsible for secretion of important neurosecretory materials & hormones. In the present investigations 3 types of NSC have been found to exist in different ganglionic mass & the brain. These types I,II and III have been identified on the basis of their specific staining reactions and cellular morphology.
