The midgut plays a major role in digestion and absorption of nutrients in insects, and contains endocrine cells throughout the epithelial layer that express neuropeptides, including crustacean cardioactive peptide (CCAP). In the present study, we demonstrate regulation of digestive enzyme activities by CCAP in response to nutrient ingestion in the cockroach, Periplaneta americana. The midgut of the cockroach exhibits maximal alpha-amylase and protease activities 3 h after intake of either… CONTINUE READING
