Esterases of Varroa destructor (Acari: Varroidae), parasitic mite of the honeybee

Experimental and Applied Acarology, 2013
Varroa destructor is an ectoparasite that causes serious damage to the population of the honeybee. Increasing resistance of the parasite to acaricides is related, among others, to metabolic adaptations of its esterases to facilitate decomposition of the chemicals used.

Evaluation of Three Concentrations of Tebufenpyrad for the Control of Varroa destructor (Acari: Varroidae)

Journal of Economic Entomology, 2003
We evaluated three concentrations of tebufenpyrad (17.5, 15 and 12.5%) in strip formulations for controlling varroa mites, Varroa destructor Anderson and Trueman (2000), in honey bee colonies. We also included colonies treated with Apistan, CheckMite+, and untreated colonies in our evaluation.

Morphotype and haplotype identification of Varroa destructor (Acari: Varroidae), and its importance for apiculture in Nicaragua

Experimental and Applied Acarology, 2021
The ectoparasite Varroa (Acari: Varroidae) is considered to be the main pest of honey bees (Apis mellifera L.) in Nicaragua. The aim of this study was to determine morphotypes and mitochondrial haplotypes of the Varroa mites, related to infestation levels in A. mellifera hives in Nicaragua in a cross-sectional study (2013-2016). Samples were taken from

Anatomical organization of the tracheal system ofVarroa jacobsoni (Acari: Varroidae)

Experimental & Applied Acarology, 1990
The respiratory apparatus of the femaleVarroa jacobsoni parasite of bees appears typically tracheal, as those of the Insecta and other Arachnida. The description is realized by means of S.E.M. (peritreme, stigma, tracheal trunk) and by means of optical microscopy after injection of cobalt naphthenat through the stigma.

Bioactivity of propolis from different geographical origins on Varroa destructor (Acari: Varroidae)

Parasitology Research, 2010
Varroa destructor is an ectoparasitic mite that affects colonies of honey bee Apis mellifera worldwide. In the last years, substances of botanical origin have emerged as natural alternative acaricides to diminish the population levels of the mite. In the present work, the bioactivity of propolis from different geographical locations of Pampean region ...

Laboratory evaluation of some plant essences to control Varroa destructor (Acari: Varroidae)

Experimental & Applied Acarology, 2002
This research was conducted to evaluate acaricidal effects of some plant essences on Varroa mites and the possibility of their usage for Varroa control. First, live Varroa mites were obtained from adult honeybees with CO2 in a newly designed apparatus. Thyme, savory, rosemary, marjoram, dillsun and lavender essences at concentrations of 2 and 1 g/100 g

Using Surrogate Insects in Acid Bioassays for Development of New Controls for Varroa destructor (Arachnida: Varroidae)

Journal of Economic Entomology, 2022
Abstract Resistance to traditional synthetic compounds by Varroa destructor Anderson and Trueman and shortcomings of the organic acid class of acaracides commonly used in varroa management requires continual development of new controls. V. destructor, however, are difficult to obtain for use in control bioassays because they are obligate

Morphological identification of the Varroa species (Acari: Varroidae) colonizing Tunisian apiaries

Systematic and Applied Acarology, 2003
The mite that attacks Tunisian honeybees (Apis mellifera intermissa L.), previously known as Varroa jacobsoni Oudemans 1904 (Acari: Varroidae), is identified as Varroa destructor Anderson & Trueman 2000, by a morphological study of many females collected throughout the country.
