Is the pamphlet on queen rearing? Buschhausen publish
Aufzucht und Verwendung von Königinnen and
Selektion bei der honigbiene. They do an annual Appendix which has useful stuff in (stockbook, etc) - all in German, of course. I once posted a copy of the pamphlet that came with the
IWF Instrumental Insemination video on here. Like most of my books, the good ones are "well read" and get a bit tatty after a while. One of these is "
Breeding techniques and selection for breeding of the honeybee" by Ruttner (translated by Ashleigh & Eric Milner) - I have read this so many times that it's falling apart!
I used to know quite a few of the BIBBA people. Not so anymore - so I can't help you identify the beekeeper you mentioned.
