Effect of Sapindus mukorossi on biochemical and physiological parameters of crab, Paratelphusa jacquemontii (Rathbun).

Crab, Paratelphusa jacquemontii (Rathbun), is important food as well as pest in the paddy field and cause destruction in Canals, dam and water reservoirs. In present investigation, toxicity of Sapindus mukorossi plant leaves was evaluated and variationsin glucose and protein content were demonstrated at 10 ppm and 20 ppm concentration for 24 and 48 hrs. Simultaneously oxygen consumption was also determined to know mode of toxicity of Sapindus mukorossi extract. Where decrease in glucose and proteins were noted while oxygen consumption was increased. This may be due to the stress, increased energy demand lead increased metabolic pathways like Glycogenolysis, and Gluconeogenesis resulted in alterations of oxygen consumption. Sapindus mukorossi extract cause toxicity and alteration of physiological state.
