Onset of oviposition in honeybee queens kept in boxes with non-free flying bees

The aim of the paper was to examine the start of egg lying by instrumentally inseminated queens kept both before and after insemination with non-free flying bees in closed boxes in a room without air-conditioning.
The experiment was carried out on queens reared from 1-day-old larvae in June and July. Sealed queen cells were introduced 1-2 days before queens emerging to boxes 130×115×70 mm settled with about 50 bees. Each box was provided with a comb, candy and a syringe with water. Queens were instrumentally inseminated twice at the age of the 7th and 9th day with 4 μl of semen. After the first insemination they were introduced to new boxes with about 250 bees and candy containing 5% pollen. Control group consisted of queens kept in trapezoid mating nuclei with about 400 bees. These queens were also instrumentally inseminated twice at the same age and with the same dose of semen.
It was found that queens kept in boxes started egg lying. However, insemination efficiency was worse than that in queens kept in nuclei. Queens in nuclei started egg lying on average 10 days after the first insemination, whereas those in boxes about 1.5 times later.
