Honey bee (Apis mellifera L.) tolerance to
Varroa jacobsoni Oud.
Those groups had an average increase in
varroa mite prevalence during the four-week period.
But according to a recent study, one threat stands well above the others, a parasitic mite,
Varroa destructor, which specialises in attacking honey bees.
Outre l'exposition, des communications etaient egalement au menu du programme traitant du

The Africanized honey bee is not free from the effects of parasites such as
Varroa destructor Anderson & Trueman 2000 (Mesostigmata: Varroidae).
The apiary had 24 Langstroth standard colonies of Apis mellifera naturally infested with
Varroa destructor.
The mite
Varroa destructor is responsible for widespread losses of honey bee colonies, particularly in North America [1-4].
Among these, the
Varroa mite (
Varroa destructor) has been shown to have a critical effect on honeybee populations, both by its direct parasitic effects and through the transmission of pathogenic viruses such as deformed wing virus (2).
The aptly named
Varroa destructor (commonly the
varroa mite) is an external parasitic mite that, like a tiny tick, attaches itself to the bee's exterior and sucks its blood (bees' yellowish blood, or hemolymph, doesn't carry oxygen, a job performed by the tracheal system, and so doesn't contain the red pigment hemoglobin).
None of the busy little winged bearers of pollen and nectar will get by without inspection: The prime suspect--an eight-legged, pinhead-sized parasite called the
Varroa mite--seems to be sneaking into the hives on the bees' bodies.
