.  So while Apis mellifera mellifera can cross with Apis mellifera ligustica
and produce fertile drones and queens, a cross between, say, Apis florea and
Apis dorsata, even if done in a laboratory, won't work.

I have been told apis cerana drones will mate with apis mellifera queens but
only the mating occurs.
occurs quite often in areas both exist.

I have never heard of a mellifera drone mating with a cerana queen.

I have been told apis cerana and apis mellifera will not cross even if done
in a lab.

I could look up as I refer to the book Asian beekeeping at times. Very
interesting book.

is the above true?
