Amitraz (Varroaset) is an acaricide applied against Varroa destructor Anderson & Trueman (Acarina: Varroidae) infestations on honeybees (Apis mellifera L.) (Hymenoptera: Apidae). Amitraz residue in honey was determined by HPLC in Ankara, Turkey. Honey samples were collected from beekeepers during the harvesting period in AyaĢ, Kızılcahamam and Polatlı towns in Ankara. Amitraz residue was found ...

The control of the southern cattle tick, Boophilus microplus (Canestrini), in Mexico and many other countries relies on chemical acaricides. Boophilus microplus has developed resistance to all major classes of acaricides in recent years. To gain a better understanding of the resistance and to develop resistance management strategies that benefit both Mexican ranchers and USDA's cattle fever tic...

The initial clinical presentation of amitraz and organophosphate poisoning may be similar. Reduced serum pseudocholinesterase supports a diagnosis of organophosphate toxicity, but there is no similar laboratory test for amitraz poisoning. A 'mothball-like' odour associated with poisoned patients may have diagnostic potential. In a blinded controlled trial, 83% (95% confidence interval, 63% to 9...

background: to determine the atmospheric contamination by pesticides, conducting laboratory studies is necessary before operating field studies. the aim of this research study was to develop an analytical method to sample and simultaneously determine airborne amitraz and its metabolite. methods: a modified fritted impinger with acetonitrile as the liquid sorbent was used in order to study the a...

Amitraz is an insecticide/acaricide of formamidine pesticides used worldwide to control ectoparasites in animals. Amitraz poisoning is a rare disorder characterized by central nervous system (CNS) and respiratory depression, bradycardia, hypotension, hypothermia, hyperglycemia,nausea and vomiting. Poisoning may occur either by oral inhalation and dermal route. In this study, we present seven pe...

In the asymmetric unit of the title compound {systematic name: N'-(2,4-di-methyl-phen-yl)-N-[N-(2,4-di-methyl-phen-yl)carbox-imido-yl]-N-methyl-methanimidamide}, C19H23N3, which is a formamidine pesticide, there are two independent and conformationally similar mol-ecules, with the dihedral angle between the mean planes of the 2,4-di-methylbenzene rings in each mol-ecule being 41.63 (6) and 42.0...

In order to determine the extent of acaricide resistance in the eastern region of the Eastern Cape Province 1-, 2- and 3-host ticks were collected from cattle at 59 dip-tanks over a period of 2 years. These ticks were tested for resistance against 3 compounds, namely amitraz, cypermethrin and chlorfenvinphos. The Shaw Larval Immersion Test detected emerging resistance to amitraz in Rhipicephalu...

This study investigated the effects of sub-chronic administration of sub-lethal doses of amitraz on some testicular parameters of Albino rats. Twenty-four adult male Albino rats (100 ± 10 g) randomly assigned into four groups were used for the study. Groups A, B and C received 10.0, 2.0 and 0.4 mg/kg amitraz in 10 ml/kg water while group D received equivalent volume of water orally and daily fo...

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...
