The objective of this study was to document the first case in Mexico of Amitraz resistance in B. microplus ticks. A sample of B. microplus ticks was obtained in the municipality of Emiliano Zapata, Tabasco, where there had been reports of lack of control with this ixodicide. The tick strain was named ",,San Alfonso",, and (F 1 ) larvae were used from the parental generation of adult engorged females. These were tested with a discriminate dose of Amitraz 0.0002%, (Taktic®) in a emulsifiable…

Detection and Characterization of Amitraz Resistance in the Southern Cattle Tick, Boophilus microplus (Acari: Ixodidae)
TLDR
A survey to measure the levels of resistance to amitraz in 15 strains of B. microplus from four major cattle-producing states in Mexico found high resistance to pyrethroids and moderate resistance to organophosphates, and multiple resistance shown in this strain and other B.microplus strains from Mexico poses a significant challenge to the management of the species.
Diagnosis of amitraz resistance in Brazilian populations of Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) with larval immersion test
TLDR
The results suggest that the test procedure by LIT is sensitive and adequate for detection and monitoring of amitraz resistance in cattle tick, and suggests that the chemical control with acaricides is still the most efficient method available to control ticks.
Evaluation of acaricide resistance in the cattle tick, 'Rhipicephalus (Boophilus) microplus', using a new in vitro test and molecular tools
TLDR
The Larval Tarsal Test is a suitable test for the assessment of the level of resistance of R. microplus and is very promising to evaluate the resistance profile of field strains and is also suitable to test other ixodid species.
Resistance of Rhipicephalus microplus to Amitraz and Cypermethrin in Tropical Cattle Farms in Veracruz, Mexico
TLDR
There is a high prevalence of R. microplus populations on cattle farms in Veracruz, Mexico that are both resistant to cypermethrin and amitraz and co-resistant to both acaricides.

A method for measuring the acaricide-susceptibility of the cattle tick Boophilus microplus (Can.)
TLDR
There was a slight increase in susceptibility of non-resistant larvae to DDT with increasing age between 7 and 28 days for fresh packets but not for re-used packets, and re-use packets were significantly more toxic to susceptible larvae than fresh packets.

TLDR
The results suggest that resistance to one or more organophosphorus insecticides will not necessarily prevent the use of other members of this wide and diverse group for tick control, and several of the insecticides shown here to be subject to low-order non-specific resistance are known to be effective tick dips.
Tests of acaricides for control of Boophilus annulatus and B. microplus.
TLDR
In laboratory tests, 4 strains of the southern cattle tick, Boophilus Microplus (Canestrini), were not resistant to 9 commonly used acaricides, and “Solubilized” formulations of both chlorpyrifos and Compound 4072 were as effective as emulsifiable formulations.
Characterization of Acaricide Resistance in Rhipicephalus sanguineus (Latreille) (Acari: Ixodidae) Collected from the Corozal Army Veterinary Quarantine Center, Panama
TLDR
T ticks collected from the Corozal Army Veterinary Quarantine Center in Panama and characterized for resistance to five classes of acaricides were highly resistant to permethrin, DDT, and coumaphos; moderately resistant to amitraz; and not resistant to fipronil when compared with susceptible strains.
Insecticides and acaricides: resistance and environmental impact.
TLDR
New chemicals are available for the control of resistant ectoparasites, but there are concerns over resistance and residues problems, which prompt the authors to discuss new pest management strategies.
