THE QUALITY OF HONEY BEE QUEENS FROM QUEEN CELLS INCUBATED AT DIFFERENT TEMPERATURES
Journal Title: Acta Scientiarum Polonorum Zootechnica - Year 2015, Vol 14, Issue 4
Abstract
The effect of capped queen cell incubation temperature on the quality of honey bee queens was examined. It was shown that the period of pre-imaginal development in the queen bees from queen cells incubated at 32°C was longer by 1 day and 3 hours when compared to those being incubated at 34.5°C, for which this period amounted to 16 days and 1 hour. On the other hand, the quality of queens from cells incubated at 32°C and 34.5°C was similar, they did not differ in body weight, spermathecal volume, ovariole number in both ovaries, or onset of oviposition.
