Formamidines are unique insecticides and acaricides that elicit multiple effects in controlling insects. Here, we tested two formamidines, amitraz, and chlordimeform, for their synergistic actions on type II pyrethroids and neonicotinoids to increase their larvicidal actions on the fourth instars of Aedes aegypti L. An organophosphate insecticide was used as a negative control. After 24 h, the ...

The southern cattle tick (Rhipicephalus (Boophilus) microplus) is a hematophagous external parasite that vectors the causative agents of bovine babesiosis or cattle tick fever, Babesia bovis and B. bigemina, and anaplasmosis, Anaplasma marginale. The southern cattle tick is a threat to the livestock industry in many locations throughout the world. Control methods include the use of chemical aca...

The efficacy of the treatment with Certifect ® (containing fipronil 6.26% w/v, amitraz 7.48% w/v, (S)-methoprene 5.63% w/v) applied topically was assessed in 18 dogs diagnosed with clinical generalized demodicosis. Three treatment regimens were compared over a 3-month period. Starting at Day 0, dogs were treated monthly (group 1) or every two weeks (group 2) with the combination of fipronil, am...

The resistance status of Rhipicephalus (Boophilus) microplus collected from SBS Nagar, Punjab, was evaluated against amitraz by Adult Immersion Test (AIT). The regression graph of probit mortality of ticks plotted against log values of progressively increasing concentrations of amitraz revealed the slope of mortality (95% CI) as 2.36 ± 0.61 (0.38 to 4.33). The LC50 (95% CI) and LC95 (95% CI) va...

South African canine babesiosis caused by Babesia canis rossi is a common clinical disease in dogs in South Africa and remains a significant cause of domestic dog mortality. To determine whether tick-repellent, 9% amitraz-impregnated tick collars (Preventic-Virbac) could prevent tick-borne exposure to B. canis rossi, 50 dogs were assigned to two groups. Group 1 (20 dogs), polymerase chain react...

The health and survival of managed honey bee (Apis mellifera) colonies are affected by multiple factors, one of the most important being the interaction between viral pathogens and infestations of the ectoparasitic mite Varroa destructor. Currently, the only effective strategy available for mitigating the impact of viral infections is the chemical control of mite populations. Unfortunately, the...

Amitraz is an insecticide that frequently used as a pesticide in the world and our country. poisoning rare usually occurs pediatric age groups. Central nervous system respiratory depression, hypotension, bradycardia hyperglycemia are mainly observed poisoned patients. There no specific antidote treatment includes symptomatic measures. Herein, we report 38-year-old male patient who ingested glas...

The evaluation of the efficacy of three commonly used acaricides viz. cypermethrin, deltamethrin (0.05, 0.1 and 0.2% concentrations) and amitraz (0.1, 0.2 and 0.3% concentrations) was conducted against the cattle tick Boophilus microplus. Three in vitro methods viz. Tea bag method, filter paper impregnation method and immersion method were used to evaluate the efficacy of the acaricides. Adult ...
