Which class of insecticides acts as cholinesterase inhibitors?

Organophosphates are a class of insecticides that function as cholinesterase inhibitors. Cholinesterase is an enzyme that breaks down acetylcholine, a neurotransmitter involved in transmitting nerve impulses. When organophosphates inhibit cholinesterase, it leads to the accumulation of acetylcholine at synapses, resulting in continuous stimulation of muscles, glands, and the central nervous system. This can ultimately cause paralysis and death in pests, making organophosphates effective for controlling various insect populations.

Understanding the mechanism of action of organophosphates is crucial for their safe and effective use, as well as for recognizing potential risks to non-target organisms, including humans. This understanding highlights the importance of proper application and adherence to safety protocols when using these insecticides.
