Prey Influence on the Salivary Gland and Gut Enzymes Qualitative Profile of Rhynocoris marginatus (Fab.) And Catamiarus brevipennis (Serville) (Heteropetera: Reduviidae)

Abstract:
Rhynocoris marginatus (Fab.) was reared on two natural lepidopteron pests [Spodoptera litura (Fabricius) and Pericallia ricini (Fab.)] and a factitious host (Corcyra cephalonica Stainton). Whereas Catamiarus brevipennis (Serville) reared on C. cephalonica, S. litura and Thunberg. Impact of these preys on the total body, midgut, hindgut and entire salivary gland weight, their enzymes qualitative profile was recorded. Total carbohydrates and lipids and more amount of proteins were observed in S. litura fed R. marginatus showed maximum total body, midgut, hindgut and salivary gland weights. Presence of more amount of total lipids and carbohydrates in M. pustulata favours the body, gut and salivary gland weight of C. brevipennis. Amylase, invertase, lipase, protease, trypsin and pepsin activities were well pronounced in the midgut than the hindgut of both reduviids. R. marginatus and C. brevipennis salivary gland expressed more amylase, invertase, protease and lipase activities.
