AbstractGross morphology of feeding canal, and salivary apparatus, protein content, enzyme profiles of Catamirus brevipennis Servile (Hemiptera: Reduviidae) salivary gland and alimentary canal were investigated. C. brevipennis has two each maxillary stylets inside and mandibular stylets outside. Maxillary stylets bear barbs where as mandibular stylets composed of filtering structures. Salivary gland is organized into larger multilobed principle gland (anterior and posterior lobes) and a shorter vesicular accessory gland. Posterior lobe of principle gland further constructed in to multilobes. At junction of anterior and posterior principle lobes of the principle gland shows a well-developed hilus. Short foregut (2.26Â±0.05 mm) was followed by very long midgut (6.02Â±0.06 mm) and hindgut (7.38Â±0.05 mm). Digestive enzymes like amylase, lipase and protease were found in both salivary gland and alimentary canal. Significantly low level of amylase and acid phosphatase and high level of protease was observed in the principle gland. Lipase activity was almost similar in both principle and accessory gland. Fore, mid and hindgut showed lipase and amylase activities. However, midgut and hindgut showed higher level of protease and acid phosphatase activity. This predatory bug is equipped purely for zoophagy by its functional morphological features and physiological nature.
