Mating biology of honey bees (Apis mellifera)

I purchased the Koeniger book at the Tri-County meeting a couple weeks back. I've been aware of the Koeniger's work involving DCA's for quite some time. However, since I don't speak German there wasn't any need to acquire any of their research papers. Through [the efforts of Wicwas Press] their work is now instantly available to one and all. This is a major contribution to the mass of practical information [Wicwas Press has] already provided. I thank you for the great work! --Roy, Satisfied Customer
