Acaricides against Boophilus microplus (Canestrini) on Holstein cattle in Trinidad


, : Acaricides against Boophilus microplus (Canestrini) on Holstein cattle in Trinidad. PANS 21(2): 158-161

Small-scale field tests were carried out in Trinidad in November 1971 to compare the toxicity and residual activity on Holstein cattle of seven acaricides against Boophilus microplus (Can.). The acaricides were a wettable-powder formulation of carbaryl (which was used as a standard of comparison) and emulsion concentrates of ethion, crotoxyphos, pyrimithate (O,O-diethyl O-(2-dimethylamino-4-methylpyrimid-6-yl) phosphorothioate), dioxathion, chlorfenvinphos or chlorpyrifos.

Retinoid X receptor (RXR) agonists are interesting candidates for the treatment of metabolic syndrome. 9-Cis-retinoic acid (9cRA: 1) is a natural RXR agonist, that also works as a retinoic acid receptor (RAR) agonist. This fact prompted us to stud...
