Honey bee (Apis mellifera L.) tolerance to Varroa
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 varroa

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
The mite Varroa
destructor is responsible for widespread losses of honey bee colonies, particularly in North America [1-4].
Among these, the 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.
