Abstract: Carbohydrate metabolism in insects follows a more or less similar pattern as in vertebrates. In insects, like other animals, glucose has a central place in carbohydrate metabolism. But in majority of insect’s species, the amount of free glucose is quite small. The most prominent sugar of haemolymph and other body tissues of insect is trehalose, a disaccharide of glucose. It has a glycocidic linkage between anomeric carbon atoms of both glucose molecules. It is a non reducing sugar. In most cases, the sugar contents in the haemolymph is relatively low level of glucose along with higher trehalose contents. In the present investigation on male Hydrophilous olivaceous it was observed that the copper sulphate had an initial carbohydrate lowering effect and latter elevating trend on the haemolymph, fat body, and testis of and male insects. Overall initial decline of the carbohydrate content in haemolymph, fat body, ovary and testes were observed in insects exposed to sub-lethal concentrations of copper sulphate.
