New Viruses from the Ectoparasite Mite Varroa destructor Infesting Apis mellifera and Apis cerana

open access: yesViruses, 2019
Varroa destructor is an ectoparasitic mite of Asian or Eastern honeybees Apis cerana (A. cerana) which has become a serious threat to European subspecies of Western honeybees Apis mellifera (A. mellifera) within the last century. V.

Genetic markers for the resistance of honey bee to Varroa destructor

open access: yesВавиловский журнал генетики и селекции, 2020
In the mid-20th century, the first case of infection of European bees Apis mellifera L. with the ectoparasite mite Varroa destructor was recorded. The original host of this mite is the Asian bee Apis cerana. The mite V.

Field efficacy of acaricides against Varroa destructor

open access: yesPLOS ONE, 2017
Field trials were conducted in Northeast Spain (Aragón) to evaluate the effectiveness of two acaricides against Varroa destructor. These experiments took into account the season of the year, apiary, colony, and developmental state and strength of the colony. The acaricides used were a synthetic (amitraz, Apivar®) and a natural (formulated from Api Life

EFFICIENCY OF FORMING NUCLEUS COLONIES IN ORDER TO DECREASE POPULATION OF Varroa destructor (ANDRESON AND TRUEMAN, 2000) IN BEEHIVES [PDF]

open access: yesPoljoprivreda, 2003
Forming of nucleus colonies is efficient method in growth control of Varroa destructor population. Its goal is to decrease parasite’s pressure on bee colony. The advantage of this bio-technical measurement lays in its implement during vegetation season

Strategy for ecologic control in fighting Varroa destructor [PDF]

open access: yesVeterinarski Glasnik, 2007
The ectoparasite Varroa destructor is one of the most wide-spread parasites of the honey bee, which is increasing its resistence to traditional synthetic acaricides more and more with each year.

Identification of broadly expressed nervous system‐related genes as effective RNAi targets in the brown marmorated stink bug, Halyomorpha halys

open access: yesPest Management Science, EarlyView.
Broadly expressed genes outperformed brain‐enriched neural targets as RNAi candidates in Halyomorpha halys. Microinjection of dsRNA targeting alpha‐soluble NSF attachment protein (Asnap) or Ras opposite protein (Rop) caused strong feeding suppression and near‐complete mortality, identifying them as promising targets for future oral or spray‐based RNAi ...

Dose‐dependent efficacy of a novel dsRNA‐based solution containing vadescana for Varroa destructor control

open access: yesPest Management Science, EarlyView.
Vadescana is a novel dsRNA‐based product that targets Varroa fecundity. Vadescana applied at 4 g/brood box in one application was most effective at reducing Varroa populations for up to 18 weeks. Abstract BACKGROUND A novel dsRNA‐based product, containing a molecule called vadescana, interferes with Varroa destructor (Anderson and Trueman) fecundity ...

Visual Diagnosis of the Varroa Destructor Parasitic Mite in Honeybees Using Object Detector Techniques

open access: yesSensors, 2021
The Varroa destructor mite is one of the most dangerous Honey Bee (Apis mellifera) parasites worldwide and the bee colonies have to be regularly monitored in order to control its spread. In this paper we present an object detector based method for health

Effect of Varroa destructor, Wounding and Varroa Homogenate on Gene Expression in Brood and Adult Honey Bees. [PDF]

open access: yesPLoS ONE, 2017
Honey bee (Apis mellifera) gene expression related to immunity for hymenoptaecin (AmHym) and defensin-1 (AmDef-1), longevity for vitellogenin (AmVit2) and stem cell proliferation for poly U binding factor 68 kDa (AmPuf68) was compared following Varroa ...
