The anticholinesterase (antiCHE) insecticides, a large family of pesticides used extensively throughout the world, inhibit serine hydrolases by carbamylating or phosphorylating a serine residue at the catalytic site.
The order of potency for T cell inhibition was carbaryl = dichlorvos > methiocarb > carbofuran > paraoxon > mevinphos > aldicarb = monocrotophos.

We conclude that the progressive accumulation of acetylcholine over time induced by a direct inhibition of Mev on cholinesterase in the NRVL may be responsible for the phasic changes in cardiovascular events over the course of acute Mev intoxication.

Evidence is given that the organo-phosphates mevinphos and malathion perturb the retinal functioning of the white mouse by acting 1. directly on the photoreceptors; 2. by a synaptolytic effect due to the inhibition of cholinesterases; 3. likely by a damage of the bipolar and/or the ganglion neurones.
