The ability of this poison to inhibit cholinesterase enzyme in the nervous system of animals. Acetylcholine acts as a neurotransmitter in the inter-synaptic space and stimulates the next axon. Fenitrothion causes accumulation in the synapse in the insect's body, and as a consequence, the subsequent stimulation of the lateral nerves continue, as the required cholinesterase enzyme for acetylcholine decomposition in the inter-synaptic space and the removal of this continuous stimulation are blocked by fenitrothion.
