Resistencia de la garrapata Boophilus microplus a los ixodicidas

Abstract

The tick is a major problem for cattle producers in subtropical and tropical areas where ticks, especially Boophilus microplus, and the disease agents that they transmit, are a constraint to cost-effective production. The aim of the present review is to present the most important findings of acaricide resistance in the B. microplus tick. The definition, development, evolution and diagnosis of tick resistance are presented. The distribution of tick resistance in the world, especially in Mexico is also presented. It is concluded that tick resistance is an important problem for cattle production and strategies need to be developed to reduce the impact on cattle. © 2006 Facultad de Ciencias Veterinarias, Universidad Austral de Chile.
