Selection pressure with the acaricide, amitraz was applied to a strain of Rhipicephalus (Boophilus) microplus (Canestrini) in 13 out of 18 generations, resulting in a 28.7-fold increase in resistance, indicating a shift in the phenotypic composition of the ticks, from a heterogenous mixture of both susceptible and resistant ticks when selection began to a homogenous composition of predominantly...

Amitraz is a triazapentadiene, an α2 adrenergic agonist and a member of the amidine chemical family. A limited number of human intoxication cases have been published in the literature. Lack of a clear and specific protocol for the therapy of amitraz intoxication may make its successfully managed case reports useful and valuable for other clinical practitioners in poisoning departments. The case...

BACKGROUND Amitraz is a pharmaceutical, veterinary, and agricultural product which is used worldwide under numerous generic names as an acaricide and insecticide. Because of its widespread use amitraz poisoning has come emerged as a cause of childhood poisoning during the past decade, particularly more in certain countries such as Turkey. AIMS AND METHODS To report the clinical features, the ...

This paper describes the validation of method for analysis of the acaricide amitraz in honey using nhexane/acetone extraction, cleanup in cartridge of solid phase extraction (SPE) and analysis by gas chromatography with nitrogen-phosphorus detector (GC -TSD). The method can be used to monitor the presence of the pesticide amitraz in honey because of its good analytical parameters, precision (CV...

The distribution constants of amitraz and its three main metabolites (DMFF, DMF, DMA) for water–organic solvent (n-hexane, toluene, dichloromethane, chloroform) extraction systems were estimated. Based on the analysis substances in studied systems, it was established that dichloromethane is optimal choice liquid-liquid method development their simultaneous determination honey. Amitraz stability...

Very few cases have been reported with Amitraz as a suicidal agent from India. Here we present such a case treated successfully with atropine sulphate.

Since Varroa mites may cause devastating losses of honey bees through direct feeding, transmitting diseases, and increasing pathogen susceptibility, chemical and mechanical practices commonly are used to reduce mite infestation. While miticide applications are typically the most consistent and efficacious Varroa mite management method, miticide-induced insecticide synergism in honey bees, and t...

The present study was conducted to obtain information on the effects of amitraz on reproductive and developmental parameters in rats. The test chemical was administered via the drinking water containing 0, 40, 120, and 360 ppm to male rats from 2 weeks before mating to the end of 14-day mating period and to females from 2 weeks before mating, throughout mating, gestation and up to lactational d...
