“…Reduced carbohydrate levels during pupation may, however, have consequences for normal development. For example, the sperm of drones parasitised by V. destructor can fail to mature properly and this has been attributed to a lack of surface glycoproteins that are important in cellcell recognition and sperm-egg fusion (DelCacho et al 1996).…”

Wet weight, dry weight and water contents of emerging honeybees (Apis mellifera L. [Hymenoptera: Apidae]) infested with the ectoparasitic mite Varroa destructor (Anderson) (Acari: Varroidae) were all negatively correlated with increasing numbers of mites. It was estimated that for every female mite present during the bees' development, the host would lose three percent of its body water. Parasitised bees also emerged with lower head and abdomen concentrations of protein and with lower abdominal carbohydrate concentrations. Lipid concentrations were not detectably affected by V. destructor infestation. The losses of metabolic reserves were not, however, judged to be serious enough to be directly responsible for the high bee mortality and ultimate colony collapse that are associated with the arrival of Varroa in a hive. Some 8.5% of the emerging bees exhibited morphological deformities and deformity was positively correlated with increasing numbers of mites in brood cells. Deformed bees were, however, found in all categories of parasitosis, suggesting that other factors, such as infectious agents, may be involved. Mites that fed on either live or dead U14C‐ labelled bees acquired the label within 24 h and it was calculated that an adult female mite consumes 0.67 μl haemolymph 24 h−1. It was also demonstrated that 14C was transmitted to a previously non‐radio‐labelled bee when a mite that had been feeding on a labelled bee changed hosts. The level of transfer was above that which could have arisen through contamination of the mites' mouthparts and supports the suggestion that Varroa is an important vector of pathogens such as viruses.

“…If so, intense selection on drones would accelerate selection even though infestation of worker bees may be insufficient to kill the colony. V. destructor kills many infested drones and many adult drones surviving infestation suffer severe reproductive impairment (Weinberg and Madel, 1985;Del Cacho et al, 1996;Rinderer et al, 1999a). Also, since drones are haploid, (Woyke, 1986) selection among drones is effectively at the gametic level, unencumbered by genetic conditions arising from heterozygosity.…”

Resistance to the parasitic mite Varroa destructor in honey bees from far-eastern Russia

et al. 2001

International audienceVarroa destructor is a parasitic mite of the Asian honey bee, Apis cerana. Owing to host range expansion, it now plagues Apis mellifera, the world's principal crop pollinator and honey producer. Evidence from A. mellifera in far-eastern Russia, Primorsky (P) originating from honey bees imported in the mid 1800's, suggested that many colonies were resistant to V. destructor. A controlled field study of the development of populations of V. destructor shows that P colonies have a strong, genetically based resistance to the parasite. As control colonies (D) were dying with infestations of ca. 10000 mites, P colonies were surviving with infestations of ca. 4000 mites. Several characteristics of the P bees contributed to suppressing the number of mites parasitizing their colonies

“…The prime victim of parasitism by Varroa mites is the drone population (Fuchs, 1990). Varroa infestation during the pupal stage hampers the life expectancy and flight abilities of drones (Schneider et al, 1988;Duay et al, 2002;Bubalo et al, 2005), as well as the development of spermatozoa (Schneider and Drescher, 1987;Schneider et al, 1988;Del Cacho et al, 1996;Duay et al, 2002Duay et al, , 2003.…”
