According to Sue Cobey:
Mackensen (1964) recommended two inseminations of 3 ěL and Harbo
(1986a) recommended 2 or 3 inseminations of 2 to 4 ěL of semen, given
a day apart. However, Woyke (1989c) stated that the difference between
single and multiple inseminations, of up to 8 ěL, were not
statistically different. Multiple inseminations require extra labor
and handling of queens, and may increase the risk of injury and
infection. Currently, the standard practice is to give each queen one
large semen dose.
The ability to pool and homogenized sperm cells from *hundreds* of
drones and inseminate a portion to a queen or batch of queens enables
unique mating system designs and simplifies stock maintenance
The demonstrated reliability of instrumental insemination as a tool
for selective breeding should encourage increased use of this
technique in bee breeding and stock maintenance programs. Many factors
affect queen performance. Beekeeping management practices and the
treatment of queens appear to have a more significant effect on queen
performance, than the actual insemination procedure.
