Huber’s Amazing “New Observations”

1. Huber’s Amazing “New Observations”

2. Presentations online • Before you take copious notes, all these presentations are online here: • http://www.bushfarms.com/beespresentations.htm

3. Who was Huber? Francis Huber 1750-1831 Born in Switzerland Started losing his sight at 15 Proved virtually every practical fact we know about bees.

4. The two volumes • Volume I is mostly about raising queens, mating queens, drone laying queens, laying workers and the formation of swarms. It was first published in 1792 in French • Volume II is about the production of wax, the architecture of the bees, respiration etc, and was first published in 1814 in French

5. How does a blind man make observations? • “I am much more certain,” said he one day to me smiling, “of what I taste than you are, for you publish what your own eyes only have seen, while I take the mean among many witnesses.” --Memoir of Huber by Professor De Candolle

6. A true scientist • Took much of the speculation of his day and constructed experiments to prove or disprove them. • Made repeatable experiments so others could verify his discoveries • Invented devices and hives to allow the appropriate observations • Measured things carefully • Carefully distinguished his actual observations from his assumptions

7. His collaborators • Francis Burnens (his servant) • Pierre Huber (his son) • Maria Aimée Lullin Huber (his wife) • Jean Senebier (a chemist) • Charles Bonnet (a naturalist) • Christine Jurine (a naturalist/artist/dissector) • John Hunter (a naturalist)

8. His discoveries • Details of the mating of the queen • Details of the forming of swarms • Details of the making of emergency queens • Details on drone laying queens • Details on laying workers • Details on the production of wax • Details of the construction of comb • Details of the respiration and ventilation of the colony • Details of the way bees guard their hives

9. Proofs • Proved that queens mate with drones (which was still in dispute) • Proved that the queen mates outside the hive • Proved that there are drone laying queens • Proved that there are laying workers • Proved that bees breath (which was still in dispute) • Proved how they ventilate the hive • Proved that wax is NOT made from pollen

10. Proofs (cont.) • Proved that nectar is the needed ingredient for wax • Proved that bees secrete wax scales from nectar • Proved that the scales are not true beeswax but are the primary ingredient • Proved that propolis comes from poplar buds • Proved that comb is reinforced with propolis and other secretions of the bees

11. Proofs (cont.) • Proved that bees need contact with the queen to know that she is there (was on the verge of proving pheromones and QMP transfer by trophalaxis) • Proved that bees can smell • Proved that they need their antennae for many things • Proved that all workers are female • Proved that combs have a “beespace” between them

12. Inventions • Invented the movable comb hive. • Invented many different observation hives to observe many different things including the construction of comb
