Worker sampling

  • Identify at least 10 colonies headed by locally mated queens.
  • Collect freshly emerged workers (ideally between 12-24 workers per colony) directly from brood combs upon opening of the hives in order to avoid sampling workers that drifted from a foreign colony into the sample hive.
    Using this approach, failing to detect some fathers in a colony would be equivalent to failing to sample some drones at a DCA.
