BACKGROUND Chemical analysis shows that honey bees (Apis mellifera) and hive products contain many pesticides derived from various sources. The most abundant pesticides are acaricides applied by beekeepers to control Varroa destructor. Beekeepers also apply antimicrobial drugs to control bacterial and microsporidial diseases. Fungicides may enter the hive when applied to nearby flowering crops....

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)....

Control While many intervention techniques have been developed and applied with varying degrees of success, it remains clear that a comprehensive method for tick control still needs to be realised, especially for resource­constrained farmers. Conventional methods involve the use of commercial acaricides under intense dipping program­ mes. In Zimbabwe, the Department of Veterinary Services (DVS)...

OBJECTIVE To evaluate hypersensitivity to Dermatophagoides pteronyssinus (D. pteronyssinus) and Dermatophagoides farinae (D. farinae) in pediatric patients with asthma, and the use of acaricides. METHODS This is a randomized controlled trial in 82 asthmatic children. They were recruited and evaluated for severity and chronicity according to the Global Initiative for Asthma Guidelines. The s...

Rapid resistance detection is necessary for the adaptive management of acaricide-resistant populations of Tetranychus urticae. Detection of phenotypic and genotypic resistance was conducted by employing residual contact vial bioassay (RCV) and quantitative sequencing (QS) methods, respectively. RCV was useful for detecting the acaricide resistance levels of T. urticae, particularly for on-site ...

Toward the end of the nineteenth century a complex of problems related to ticks and tick-borne diseases of cattle created a demand for methods to control ticks and reduce losses of cattle. The discovery and use of arsenical solutions in dipping vats for treating cattle to protect them against ticks revolutionized tick and tick-borne disease control programmes. Arsenic dips for cattle were used ...

In Switzerland the acaricides Folbex VA (bromopropylate, BP), Perizin (coumaphos, CM), Apistan (fluvalinate, FV) Bayvarol (flumethrine, FM) are used for varroa control. We studied the contamination level of BP,CM and FV in brood and honey combs, sugar feed, honey after field trials. In samples of recycled pure beeswax and propolis, gathered by beekeepers we examined the level of all four acaric...

Population abundance of red spider mite, Tetranychus urticae Koch., was studied in cucmber, ribbed gourd, bitter gourd, snake gourd, aroids and teasle gourd and efficacy of four new acaricides were tested against this pest in brinjal at the farmer’s field of Norsingdi during 2009-2010. At the same time, the spatial distribution of this pest in brinjal crop was also studied. Results indicated th...

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 ...

OBJECTIVE To evaluate hypersensitivity to Dermatophagoides pteronyssinus (D. pteronyssinus) and D. farinae in pediatric patients with atopic dermatitis (AD), and to assess the therapeutic value of using acaricides with other environmental anti house dust mites (HDM) measures. METHODS Ninety-eight children with AD were chosen randomly from the Pediatric Allergy Clinic in Al-Noor Hospital, Khal...
