Abstract : Experiments were carried out to find the effect of three pesticides cypermethrin (pyrethroid), malathion (organophosphate) and biosal (phytopesticide) on wildlife species of reptile Calotes versicolor. Two different concentrations i.e. 0.1 and 1% for cypermethrin and malathion and 25 and 50% for biosal were used. It was observed that cholinesterase activity decreased upto 27 and 54% in kidney and 20 and 35% in liver under the effect of cypermethrin. Under the effect of malathion cholinesterase decreased upto 58.46 and 65.09% in kidney and 30.27 and 66.97% in liver while under treatment of biosal cholinesterase activity decreased upto 13.06 and 18% in kidney and 39.52 and 52.61% in liver, respectively. The results are compared with those reported in the literature todate. , Experiments were carried out to find the effect of three pesticides cypermethrin (pyrethroid), malathion (organophosphate) and biosal (phytopesticide) on wildlife species of reptile Calotes versicolor.
