About the pest

Varroa and tropilaelaps mites

  • external parasitic mites that feed on the haemolymph of both drone and worker bee larvae, pupae and adult bees
  • detection possible by close examination of brood or testing of adult bees
  • symptoms include deformed pupae and adults (stunting, damaged wings, legs and abdomens), parasitic mite syndrome and colony decline
  • varroa and tropilaelaps mites can also spread viruses, further affecting the colony’s health and disease susceptibility

Tracheal mites

  • internal parasite of the honey bee respiratory system
  • affects the honey bee’s capacity to breathe, resulting in weakened and sick honey bees which have a reduced lifespan
  • symptoms include population drop, bees crawling on the ground and bees holding their wings at odd angles (‘K wing’)
  • accurate identification requires dissection and microscopic examination of trachea
