TLDR
The number of days from emergence to the onset of oviposition in 7 groups of queens was 10·33 ± 0·68, and naturally mated queens started laying eggs earlier than the instrumentally inseminated queens.Abstract:
SummaryThe number of days from emergence to the onset of oviposition in 7 groups of queens was as follows: naturally mated queens, 10·33 ± 0·68; free-flying queens treated with CO2, 11·00 ± 0·36; queens instrumentally inseminated by the Mackensen technique, 13·8 ± 1·94; virgin queens treated with CO2, 14·00 ± 0·77; queens instrumentally inseminated, using the washing technique, 14·58 ± 0·53; queens injected with washing fluid, 15·82 ± 1·42; queens injected with Kiev solution, 17·77 ± 1·24. The number of spermatozoa in the spermatheca of naturally mated queens, of queens inseminated by the Mackensen technique, and of queens inseminated by the washing technique, was 4·54 ± 0·7, 3·83 ± 0·47, and 3·02 ± 0·52 millions, respectively. Naturally mated queens started laying eggs earlier than the instrumentally inseminated queens.read more

Aging and development in social insects with emphasis on the honey bee, Apis mellifera L
TL;DR: For example, the developmental trajectory of a female larva from worker into a queen can be determined as late as the third day of larval development, after this time the developmental pathway is fixed for a worker phenotype.

Comparison studies of instrumentally inseminated and naturally mated honey bee queens and factors affecting their performance
TL;DR: The collective results of the data demonstrate that the different methodologies used, in the treatment of queens, has a significant affect on performance rather than the insemination procedure.

Effects of insemination quantity on honey bee queen physiology.
TL;DR: It is demonstrated for the first time that insemination quantity significantly affects mandibular gland chemical profiles, queen-worker interactions, and brain gene expression in honey bee queens.

TL;DR: Genotypic differences in rates of worker behavioral development can influence the phenotype of a honey bee colony in a variety of ways, and there was a positive correlation between rate of individual behavioral development and the intensity of colony flight activity.

Queen reproductive state modulates pheromone production and queen-worker interactions in honeybees
TL;DR: These studies suggest that the queen pheromone blend is modulated by the reproductive status of the queens, and workers can detect these subtle differences and are more responsive to queens with higher reproductive potential.

TL;DR: A simple and fast method for collecting honeybee semen in large quantity is described, and there was a delay before oviposition by all the instrumentally inseminated queens, which was greatest for queens inSEminated with semen col...

Relation of Semen Volume to Success in Artificial Insemination of Queen Honey Bees
TL;DR: As amount of semen was increased, the number of sperm reaching the spermatheca increased, but the percentage decreased; but with higher amounts (20-36 μl) the death rate increased and oviposition was sometimes much reduced.

Effects of Carbon Dioxide on Vitellogenin Metabolism in Unmated Queen Honeybees
TL;DR: It is concluded that there was social conditioning of the queen's vitellogenin metabolism, which resulted in a slight decline in the viteLLogenin content of the haemolymph, and also an increase of about 50% in the body weight.

TL;DR: Queen honeybees instrumentally inseminated with 8 μl semen during narcotization with one application of 50, 60, 70, 80, 90, or 100% CO2 or low temperature, contained a mean of 2·05 and 4·64 million sperm, respectively, whereas naturally mated queens had 47middot;96 million.
