Malathion is an organophosphate insecticide which acts as an acetylcholinesterase inhibitor. In the USSR , it was known as carbophos , in New Zealand and Australia as maldison and in South Africa as mercaptothion .

Organophosphate and carbamate insecticides, e.g. malathion and bendiocarb, respectively, are more expensive than DDT per kilogram and are applied at roughly the same dosage. Pyrethroids such as deltamethrin are also more expensive than DDT, but are applied more sparingly (0.02–0.3 g/m 2 vs 1–2 g/m 2 ), so the net cost per house per ...
The former is a precursor to malathion. In the Michalski reaction , a thiophosphate reacts with chlorine gas to give a diorganylphosphorylsulfenyl chloride: [ 5 ] (RO) 3 PS + Cl 2 → (RO) 2 P(O)SCl + RCl
Isomalathion is an impurity found in some batches of malathion. Whereas the structure of malation is, generically, RSP(S)(OCH 3) 2, the connectivity of isomalathion is RSPO(SCH 3)(OCH 3). It arises by heating malathion. Being significantly more toxic to humans than malathion, it has resulted in human poisonings. [1]
The victim's stomach contents and body fat were examined and found to have contained malathion. The fly larvae of Chrysomya megacephala and Chrysomya rufifacies were also present at the scene on the body and were tested for malathion. Both of these species did contain malathion, but there had been no previous record of organophosphates in their ...
Malathion is an organophosphate parasympathomimetic which binds irreversibly to cholinesterase. Malathion is an insecticide of relatively low human toxicity. In the former USSR, it was known as carbophos, in New Zealand and Australia as maldison and in South Africa as mercaptothion.[3] Suggested replacement text. Malathion is an insecticide.
Symptoms of exposure to this type of compound include cholinesterase inhibition, miosis, frontal headache, increased bronchial secretion, nausea, vomiting, sweating, abdominal cramps, diarrhea, lacrimation, increased salivation, bradycardia, cyanosis and muscular twitching of the eyelids, tongue, face and neck, possibly progressing to convulsions.
