Conteúdo: 	Parasitic instars of B.microplus phosphorus-resistant were collected and imersed, for 15 seconds in water in dilutions of commercial preparation of Ethion. Amitraz and Sodium Arsenite. The data were recorded every 24 hrs. The emulsion of the active ingredient (a.l.) of Ethion  0,12% showed a lethal action of 98,75% for infestive larvae and of 100% for neandros and gonandros and it showed less intensity of action the other insta4rs. The emulsion of Amitraz 0,025% (a.i.) did not show lethal action to the infestive larvae but showed only a slight lethal action to nenadors and gonandros, which had respectively 77,5% and 68,75% lethality. It was concluded that this technique offers good information about the action of acaricides, except for parasitic larvae and ninphs because of their low survival rate oustside the host's body. It was also observed a strong variation of susceptibility among the parasite instars of given strain and in genetal the young instars showed less sensitivity to the action of the acaricides.
