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

Five strains of Rhipicephalus (Boophilus) microplus collected from Tamaulipas Mexico were tested for resistance against several classes of acaricides commonly used. All were resistant to fipronil. Four of five were co-resistant to permethrin and coumaphos in addition to being resistant to fipronil. ...

Abstract

Background: Rhipicephalus (Boophilus) microplus is a highly-invasive tick that transmits the cattle parasites (Babesia bovis and B. bigemina) that cause cattle fever. R. microplus and Babesia are endemic in Mexico and ticks persist in the United States inside a narrow tick eradication quarantine...

AbstractFull Text

Ticks and tick-borne diseases cause many problems to the cattle industry worldwide. This study investigated the prevalence of strains of Rhipicephalus microplus resistant to different acaricides on cattle farms in the tropical region of Tecpan of Galeana, Guerrero, Mexico, and risk factors related...

AbstractFull Text

Ticks and the diseases they transmit cause great economic losses to livestock in tropical countries. Non-chemical control alternatives include the use of resistant cattle breeds, biological control and vaccines. However, the most widely used method is the application of different chemical classes...

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

A field survey was conducted to evaluate susceptibility of Rhipicephalus (Boophilus) microplus to cypermethrin on 49 farms in three areas of Yucatan, Mexico. The modified larval packet test was used to evaluate larval mortality at different cypermethrin concentrations. Dose-mortality regressions,...

Abstract

A study was conducted to evaluate the efficacy of cypermethrin, amitraz, and piperonyl butoxide (PBO) mixtures, through in vitro laboratory bioassays and in vivo on-animal efficacy trials, for the control of resistant Rhipicephalus (Boophilus) microplus on cattle in the Mexican tropics. Also, to...

Abstract

The aim of the present study was to evaluate the ixodicide efficacy of the experimental compound 712-BF-016 against Rhipicephalus (Boophilus) microplus ticks in vitro and in cattle. The in vitro efficacy was initially tested against R. Boophilus microplus larvae using the Larval Packet Test (LPT)....
