31. It is then emptied directly into the alimentary canal, at the junction between the midgut and hindgut. 32. It was isolated from the midgut of the malaria mosquito " Anopheles arabiensis " from Kenya. 33. The midgut bacteria of susceptible larvae may be required for " B . thuringiensis " insecticidal activity. 34. As stated, in development a loop of midgut herniates outside of the abdominal cavity into the umbilical cord. 35. After ingestion, the microfilariae migrate from the midgut through the hemocoel to the thoracic muscles of the arthropod. 36. The NPV which enters the insect gut, lyses in the alkaline environment of the midgut , releasing virions. 37. The solubilized toxin proteins are cleaved by midgut proteases to smaller toxic polypeptides that attack the gut epithelial cells. 38. Concentrating enzymes and food substrate within the endoperitrophic space significantly decreases the time required for digestion in the midgut . 39. During fetal life, the primitive gut is gradually patterned into three segments : foregut, midgut , and hindgut. 40. It is produced in the midgut glands and secreted into the haemolymph, whence it is transported to the eggs.
