Water hyacinth growth is kept under control by the week eating weevils, Neochetina eichhornae (Warner) and N. bruchi (Hustache). Water hyacinth is generally considered an aquatic weed because it clogs waterways, although it has recently been evaluated as a potential biological filter for sewage effluents. Water hyacinth plants are continuously subjected to contamination by mercury and other heavy metals from industrial effluents and fertilizer impurities. Little is known about the interaction of heavy metals/plants/insects. Aminotransferases are generally considered as indices for metabolic disturbances during Hg exposure. These enzymes are key enzymes for transamination, i.e., transfer of amino group from amino acid to keto acids which are ubiquitous in insects. The objective of the present study was to examine the bioaccumulation of mercury through the food chain in Neochetina eichhornae and its impact on protein metabolism.
