Free sugars in the reproductive system and haemolymph of the bedbug

  • Hari V. Rao


Using chromatographic procedures, two free sugars glucose and trehalose have been detected in the reproductive tissues and the haemolymph ofCimex. The seminal fluid and not the sperm has been found to possess trehalase activity. A novel feature of the metabolism of the active sperm is enzymic hydrolysis of trehalose, followed by oxidative utilisation of the hexose thus formed. The process is termed here “trehalolysis”. The depletion of the sugars has been demonstrated semiquantitatively by paper chromatography.
