Host associations, feeding, and dispersal

  • All stages live in beehives inside capped brood cells, where they parasitize developing bees by feeding on their hemolymph.
  • Mite females disperse on adult bees and feed during phoresy.


The biology of the two species in this genus is summarized after Sammataro et al., 2000. Euvarroa sinhai is a parasite of Apis florea, occurring in Asia from Iran through India to Sri Lanka. The mite develops naturally on the capped drone brood but has been reared in the laboratory on A. mellifera worker brood. Development requires less than one week, and each female produces four to five offspring. Drones as well as workers are used for dispersal. The female mite overwinters in the colony, probably feeding on the clustering bees. Colony infestation by E. sinhai is somewhat hindered by the construction of queen cells, and its population growth is inhibited in the presence of Tropilaelaps clareae and Varroa destructor. Transfer experiments confirmed that E. sinhai may survive on A. mellifera and A. cerana, emphasizing its ability to cross-infest exotic hosts.

Euvarroa wongsirii parasitizes drone brood of Apis andreniformis in Thailand and Malaysia. Its biology appears similar to E. sinhai, and it can live for at least 50 days on worker bees outside the nest.
