Chlorpyrifos affects the nervous system by inhibiting the breakdown of acetylcholine (ACh), a neurotransmitter. When insects are exposed, chlorpyrifos binds to the active site of the cholinesterase (ChE) enzyme, which prevents breakdown of ACh in the synaptic cleft. The resulting accumulation of ACh in the synaptic cleft causes overstimulation of the neuronal cells, which leads to neurotoxicity and eventually death. On other hand, Cypermethrin is a composite non-systemic pyrethroid, a broad spectrum, non-cumulative insecticide and a fast-acting neurotoxin with good contact and stomach action.
Environmental toxicity: The main mechanisms of action is to cause neurotoxic long-term effects and developmental toxicity. When they applied together, the organophosphates enhance pyrethroids toxicity. Pyrethroids like cypermethrin are broken down by esterases enzymes and the same enzymes are phosphorylated and therefore made dysfunctional by organophosphate. Hence, the conclusion is that two kinds of insecticides are in synergism and the toxicity of cypermethrin in combination with an organophosphate insecticide is greater than the toxicity of either insecticide alone.
The combination is highly toxic for fishes like Rainbow trout and Carp.
The combination is also toxic for bees.
