Hello Gentlepeople With snow on the ground and the bees all clustered up for winter.I'm taking on a project and have had a hard time finding some information. I would appreciate information on any research which determined a mean level of (E_)-9-Hydroxy-decenoic acid (9-HDA) and (E_)-9-oxo-2-decenoic acid (9-ODA) in queen bees.I want to quantify the levels so new queens may be tested for 9-ODA and 9-HDA.If any researcher has used this to determine the acceptability of a new queen to a hive. I have read many papers and have not found much more than the queen has the compounds and uses them to control different behaviors of the workers. Its much more complex than just two compounds.In Bee Genetics and Breeding By Dr. Rinderer 1986,he has me looking at what genetic variability we have in our queens, that controls there pheromone level. Thank you for your time. Roy Nettlebeck Tahuya River Apiaries Tahuya Wash. 98588
