Abstract

This paper reviews the current status and mechanisms of resistance to commonly used acaricides in Mexican strains of the southern cattle tick, B. microplus. Resistance to organophosphates (OPs) and pyrethroids was measured using the FAO Laval Packet Test (LPT), and a modification of the FAO-LPT was ...

Abstract

A cross-sectional study was carried out in order to investigate the association between management risk factors and the prevalence of organophosphate (OP) and synthetic pyrethroid (SP) resistance in Boophilus microplus ticks in Yucatan State, Mexico. Ninety-eight cattle ranches were randomly...

Abstract

The objective of this study was to document the first case in Mexico of amitraz resistance in Boophilus microplus taken from cattle. Samples of B. microplus were obtained from the municipality of Emiliano Zapata, Tabasco, where there had been reports of lack of control with amitraz. The tick strain ...

Abstract

The cattle tick Boophilus microplus causes significant economic losses in cattle in the tropical areas of Central and South America. Acaricides are widely used to control tick infestations, with the consequent selection of tolerant and resistant subpopulations. Detoxifying enzymes, and esterases in ...

Abstract

Twenty four Hereford heifers free of anaplasmosis were allotted into three groups of eight animals each and inoculated three times with adjuvant in Puck saline as control or 50 µg and 100 µg of total protein of Anaplasma marginale initial bodies from three Mexican strains which share the same...

Abstract

The suitability of white-tailed deer (Odocoileus virginianus) as hosts for the cattle ticks Rhipicephalus (Boophilus) microplus and Rhipicephalus (Boophilus) annulatus, has been well documented. These ticks have a wide host range, and both transmit Babesia bovis and Babesia bigemina, the agents...

Abstract

A population of Rhipicephalus (Boophilus) microplus (Canestrini) (Acari: Ixodidae), designated Coatzacoalcos, sampled from a ranch near Veracruz, Mexico, was found to possess a high level of resistance to pyrethroid-based acaricides. Bioassay and biochemical and molecular analysis had previously...

Abstract

A study was conducted to determine the optimal dose of a combined, frozen immunogen containing in vitro culture-derived strains of Babesia bovis and B. bigemina. 24 14-month-old Bos taurus steers from a Boophilus microplus-free area in Northern Mexico were used in this experiment. Cattle were...

Abstract

Mexican strains of Boophilus microplus that are highly resistant to coumaphos, an organophosphate pesticide, constitute a major threat to the U.S. Cattle industry. The most resistant strain studied to date has been demonstrated to survive the dipping procedure used at the border as part of an...

Abstract

Aim: Climate change has the potential to have an impact on the distribution of ticks and tick-borne diseases. This paper identifies the changes in climate suitability for the tick Rhipicephalus (Boophilus) microplus in the Americas by analysing climate data for the period 1950-99. Location: The...
