Amitraz

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. Its 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.

Use

Amitraz is particularly effective against acarids, but it is used as a pesticide in many different fields. Therefore, amitraz is available in many different forms, such as a wettable powder, an emulsifiable concentrate, a soluble concentrate/liquid, and an impregnated collar (for dogs). It is characterized as an insect repellent, insecticide, and pesticide synergist. These are the properties which make it especially useful as a pesticide:
