Abstract : Proteins are complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen and usually sulphur and are composed of one or more chains of amino acids. These are fundamental components of all living cells and include many substances, such as enzymes, hormones and antibodies that are necessary for proper functioning of an organism. Various aspects of protein metabolism in insect development, such as the pattern of free amino acid pool, the intermediary pathway of individual amino acids and their derivatives, qualitative and quantitative changes in
haemolymph and whole body protein synthesis and activity of specific enzymes have been studied by many insect’s biochemists.1-7 It is well known fact that the copper sulphate is an important hazardous water pollutant. The effect of which can be felt at all bio-chemical parameters of an aquatic life. The bio-assay experiment in the present investigation, it was realized that Copper Sulphate badly affected the protein metabolism at different levels in mature females of H. olivaceous. Copper sulphate act as major toxicants which affect all body actions directly or indirectly of all aquatic organisms. Almost all heavy metals are toxic at higher concentration and some are severely poisonous even at low concentration. In present investigation on mature female Hydrophilous olivaceous, it was observed that copper sulphate had an initial protein lowering effect and latter elevating trend on the haemolymph, fatbody and ovary of female insect. Overall initial decline of the protein content in haemolymph, fatbody and ovary were observed in insect exposed to sublethal concentration of copper sulphate.
