Abstract：Trehalose is a nonreducing disaccharide in which the two glucose units are linked in an A, A-1, 1- glycosidic linkage. As the main blood sugar in insects, trehalose plays an important role in metabolism and stress resistance in insects. The paper reviewed the discovery of trehalose and its chemical properties, physiological function and catabolism pathways of trehalose in insects as well. The further research of trehalose was prospected in the end of the paper.
