The effect of an organophosphorus (OP) insecticide, methyl parathion on the behaviour of a freshwater air breathing teleost fish, the Climbing perch, Anabas testudineus was studied. The breathing rate, rate of feeding, performance of sustained swimming behaviour against water current and the learning ability were severely curtailed in the fish exposed to 5 mg/L of methyl parathion.

Oral administration of the insecticide endosulfan (2 mg/kg per day) for 90 days in immature male rats resulted in an inhibition of pole-climbing escape response to electric shock (unconditioned) and avoidance response to buzzer (conditioned). These responses reflect respectively their learning and memory processes.
