NOMENCLATURE: Common name Amitraz IUPAC name N-methylbis(2,4-xylyliminomethyl)amine Chemical Abstracts name N'-(2,4-dimethylphenyl)-N-[[(2,4-dimethylphenyl)imino]methyl]-N-methylmethanimidamide CAS RN [33089-61-1] EEC no. 251-375-4


Amitraz (development code BTS27419) is a non-systemic acaricide and insecticide. It was first synthesized by the Boots Co. in England in 1969. Amitraz has been found to have an insect repellent effect, works as an insecticide and also as a pesticide synergist.

It's effectiveness is traced back on alpha-adrenergic agonist activity, interaction with octopamine receptors of the central nervous system and inhibition of monoamine oxidases and prostaglandin synthesis. Therefore it leads to overexcitation and consequently paralysis and death in insects. Because amitraz is less harmful to mammals, amitraz is among many other purposes best known as insecticide against mite- or tick-infestation of dogs.


Biochemistry Mode of action probably involves an interaction with octopamine receptors in the tick nervous system, causing an increase in nervous activity. Mode of action Non-systemic, with contact and respiratory action. Expellent action causes ticks to withdraw mouthparts rapidly and fall off the host animal.

Control of all stages of tetranychid and eriophyid mites, pear suckers, scale insects, mealybugs, whitefly, aphids, and eggs and first instar larvae of Lepidoptera on pome fruit, citrus fruit, cotton, stone fruit, bush fruit, strawberries, hops, cucurbits, aubergines, capsicums, tomatoes, ornamentals, and some other crops. Also used as an animal ectoparasiticide to control ticks, mites and lice on cattle, dogs, goats, pigs and sheep.
