title: Control of psoroptic scabies of cattle with fenvalerate.
abstract: Fenvalerate [Cyano(3-phenoxyphenyl)methyl-4-chloro-alpha-(1-methylethyl) benzene acetate] was evaluated as a one- or two-dip treatment at two different concentrations against cattle infested with Psoroptes ovis (Hering). One or two dips at 0.025% or one dip at 0.05% failed to eliminate P. ovis; two dips in fenvalerate at 0.05% provided complete elimination of all mites. Fenvalerate was equally effective against male, female, and immature mites, but did not exhibit ovicidal properties.
