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.

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

Why rotation and mixture fail: treatment history and the declining acaricide efficacy in Varroa destructor

open access: yesPest Management Science, EarlyView.
The effect of IRM strategies (rotation, mixture), one additional year under acaricide treatment (Years treated (+1 year)), and one year without acaricide treatment (Years off treatment (+1 year) on mite mortality relative to an approximately 17% baseline.

Comparison of nonchemical, organic and synthetic Varroa destructor control strategies in honey bee colonies: effects on parasite load, colony strength and health

open access: yesPest Management Science, EarlyView.
Combining intensive drone‐brood removal with brood interruption provided the most effective and consistent seasonal Varroa control. Abstract BACKGROUND Varroa destructor remains the most significant biotic threat to honey bee colonies, and increasing resistance to synthetic acaricides necessitates alternative control strategies.

Reproduction of Varroa destructor in sealed worker bee brood cells of Apis mellifera carnica and Apis mellifera syriaca in Jordan [PDF]

open access: yes, 2008
The reproduction of the honey bee mite, Varroa destructor in sealed worker bee brood cells represents an important factor for the population development of this parasite in honey bee colonies.

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 ...

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Infestation levels of Varroa destructor in local honey bees of Jordan [PDF]

open access: yes, 2008
To determine Varroa mite infestation levels in Jordan, a survey covering 180 colonies of two bee types (Apis m. syriaca and Apis m. syriaca hybrids) from six locations of 4 climatic zones was conducted during August, 8 month after the last treatment ...

On the front line: quantitative virus dynamics in honeybee (Apis mellifera L.) colonies along a new expansion front of the parasite Varroa destructor.

open access: yesPLoS Pathogens, 2014
Over the past fifty years, annual honeybee (Apis mellifera) colony losses have been steadily increasing worldwide. These losses have occurred in parallel with the global spread of the honeybee parasite Varroa destructor.
