18.104.22.168. 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.
