Abstract

The objectives of this study were: (1) to determine the prevalence and factors associated with Rhipicephalus microplus, resistant to cypermethrin and amitraz, from cattle farms in Veracruz, Mexico, and (2) to determine in vitro mortality percentages of field populations of R. microplus exposed to...

Abstract

In the Neotropics the control of tick infestations in red deer (Cervus elaphus) is achieved primarily through the use of acaricides and macrocyclic lactones. In Mexico, resistance to one or multiple classes of acaricides has been reported in Rhipicephalus microplus infesting cattle, but information ...

Abstract

The study was conducted to determine the level of resistance of Boophilus microplus field strains to cypermethrin from 31 cattle farms in the state of Yucatán, Mexico. The larval package technique was used and the Probit analysis was applied in order to obtain both lethal concentrations of 50 and...
