Abstract

The aim of the study was to develop a simulation program in spreadsheets using Excel® to estimate the economic thresholds of acaricides used in the Rhipicephalus microplus tick control. The economic threshold is the population density of the parasite with which the decision is made to initiate a...

Abstract

The objective of this study was to isolate, clone, and characterize a fragment of the vitellogenin (Vg) gene from a B. microplus tick strain from Mexico. Using cDNA and specific primers, an 1800-bp fragment was amplified, cloned, and transformed in into E. coli, and then sequenced. Comparative...

Abstract

The influence of host presence on the percentage of Boophilus microplus larvae recovery from experimentally infested plots with 3 grass species was examined in a trial carried out in Jiutepec, Morelos, Mexico, during autumn 1999 and winter 1999-2000. Four sampling methods were compared: human...

Abstract

The aim of this study was to describe the genetics of amitraz resistance evolution and to obtain the independent genes number involved. Three Mexican R. microplus tick strains were used, one susceptible to all acaricides and two amitraz-resistant. Larvae were reared on isolated naïve-heifers and...

Abstract

The objective of this work was to study the reproductive behavior of two strains of R. (B.) microplus, one wild-caught (Native) and one reference strain (Media Joya) for two years, measuring the reproductive efficiency index (REI) and reproductive aptitude index (RAI). Engorged ticks from each...

Abstract

The purpose of this study was to determine the effect of amitraz selection pressure on the development of resistance in field populations of Boophilus microplus in the Mexican tropics. Three farms (FA1, FA2 and FA3) in Yucatan, Mexico, were selected in this study. Amitraz was applied as a whole...

Abstract

A substitution (Phe→Ile) within the sodium channel gene sequence has been associated with pyrethroid resistance in Boophilus microplus[Rhipicephalus microplus]. The aim of the present study was to analyse the inheritance of pyrethroid resistance and the mutant allele, on reciprocal crosses of a...

Abstract

This manuscript provides a summary of the results presented at a symposium organized to accumulate information on factors that influence the prevalence of acaricide resistance and tick-borne diseases. This symposium was part of the 19th International Conference of the World Association for the...

Abstract

Dialelic crosses and backcrosses of pyrethroid resistant (RR) and susceptible (SS) Rhipicephalus (Boophilus) microplus tick strains were carried out and the substitution (Phe-Ile) within the sodium channel gene was monitored in order to analyze the effects of the genotype on the pyrethroid...

Abstract

The acaricidal activity of crude extracts and fractions from stems and leaves of Petiveria alliacea (Phytolaccaceae) was carried out on larvae and adults of the cattle tick Rhipicephalus (Boophilus) microplus using the larval immersion test (LIT) and adult immersion test (AIT), respectively....
