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...

The common pistachio psylla, Agonoscena pistaciae (Homoptera: Psyllidae) is known as the key pest of pistachio trees in Iran. This study was carried out during three years to test the effect of dish washing detergent (Rika ® ) against this pest in a randomized complete block design with five treatments and four replicates. The treatments were including: 13500ml dish washing detergent per 1000 l...

amitraz is one of the pesticides which is used in a vast area for controlling of the common pistachio psyllid, agonoscena pistaciae (hem.: aphalaridae). in this study the synergistic effect of piperonyl butoxide (pbo) on the toxicity of amitraz on adults of rafsanjan population of common pistachio psyllid was evaluated by residual contact vial (rcv) in laboratory conditions. the results showed ...

Four acaricides (amitraz, cyfluthrin, permethrin, and pyrethrins) were studied for their efficacy in the rapid killing of Amblyomma americanum, A. cajennense, and A. maculatum (Acari: Ixodidae) and eight acaricides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, fipronil, permethrin, pyrethrins, and selamectin) for their efficacy in the rapid killing of Rhipicephalus sanguineus (Acari: Ixodidae)....

The effects of amitraz, a formamidine derivative on isolation-induced aggression were studied in mice. Results show that amitraz increased the latency to the first attack and increased not only the fight duration but also the frequencies of attacks and tail (lickings. These results suggested that pesticide effects on aggressive behavior could be a consequence of it’s inhibitory effects on monoa...

The efficacy of an amitraz/cypermethrin pour-on preparation (1% w/v each) was tested against natural tick infestations of buffaloes, eland and blesbok in three separate trials. The eland were also treated with a 0.02% abamectin (w/v) acaricidal pour-on preparation. The amitraz/cypermethrin pour-on was effective against Amblyomma hebraeum, Rhipicephalus evertsi evertsi, Rhipicephalus appendicula...

The effects of epidurally amitraz (0.4mg/kg), xylazine (0.05mg/kg) or 10% dimethyl sulfoxide (5.0ml) over heart rate (HR), systolic arterial pressure (SAP), respiratory rate (RR), ruminal motility (RM), rectal temperature (RT), head height (HH), and latency to heat-evoked reflexes (LSPR – skin of perineal region; LHWR – hoof withdrawal reflex) were evaluated in cows. HR and RM decreased in amit...
