Number of spermatozoa in the spermatheca of instrumentally inseminated queen honeybees



Number of spermatozoa in the spermatheca of instrumentally inseminated queen honeybees



Biroekteren 92(3): 41-48



Six tables present results of comparisons between effects of various factors in determining the number of spermatozoa that reach the queen's spermatheca (N). Semen stored for some days could be used, but N was lower than with fresh semen. N should be 3 X 106, but was more than 2 X 106 only with queens 7 days or older. Conditions of storage of queens was important. Trouble could occur with semen left in the oviducts, but 2 or 3 inseminations each with less semen avoided this.
