Abstract

The persistent efficacy of 3.15% ivermectin (3.15% IVM) and 10% moxidectin (10% MOX) against natural Rhipicephalus (Boophilus) microplus infestations in cattle in the Mexican tropics was evaluated. Thirty three (33) female cattle were distributed among three treatment groups (n=11), (a) 3.15% IVM...

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 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 objective of the present study was to determine simultaneously the status of resistance against ivermectin (IVM) in gastrointestinal nematodes (GIN) and Rhipicephalus microplus (Canestrini, 1888) ticks in 12 cattle farms where IVM was used for the control of GIN in the Mexican tropics. Six...

Abstract

Rhipicephalus microplus is the most economically important cattle tick in the Mexican tropics. Wild ungulate species, including red deer (Cervus elaphus), are gaining popularity in diversified livestock ranching operations in Mexico. However, there is no information available on the susceptibility...

Abstract

Engorged females of Rhipicephalus microplus were collected from 30 cattle farms in Yucatan, Mexico to evaluate ivermectin resistance. The larval progeny of each tick sample were produced in laboratory and evaluated using the larval immersion test to obtain the larval mortality....

Abstract

The efficacy and persistence of ivermectin-3.15% (IVM-3.15%) and moxidectin-10% (MOX-10%) against natural infections of gastrointestinal nematodes (GIN) in cattle in the Mexican tropics were evaluated. Thirty-three heifers were divided into three groups of 11 animals each, receiving the following...

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

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...
